The transmitter emits an electrical impulse, which the transducer converts into a sound wave and sends into the water. (The sound frequency can't be heard by humans or fish.) The sound wave strikes an object (fish, structure, bottom) and bounces back to the transducer, which converts the sound back into an electrical signal. The receiver amplifies this return signal, or echo, and sends it to the display, where an image of the object appears on the scrolling sonar chart. The sonar's microprocessor calculates the time lapse between the transmitted signal and echo return to determine the distance to the object. The whole process repeats itself several times each second.

Transducer Installation

Preparations
The following shows the recommended sequence for installing the transducer: CAUTION: You should read over this entire installation section before drilling any holes in your vehicle or vessel! 1. Determine the approximate location for the sonar unit, so you can plan how and where to route the cables for the transducer and power. This will help you make sure you have enough cable length for the desired configuration. 2. Determine the approximate location for the transducer and its cable route. 3. Determine the location of your battery or other power connection, along with the power cable route. 4. Install the transducer and route the transducer cable to the sonar unit. 5. Route the power cable from the unit's location to an appropriate power source and connect it there. 6. Connect the transducer/power cable to the unit and mount the sonar unit on the bracket.

Installation

These instructions will help you install your Skimmer transducer on a transom, on a trolling motor or inside a hull. Please read all instructions before proceeding with any installation. Your Skimmer transducer typically comes packaged with a one-piece stainless steel bracket for mounting it to the transom of your boat. The 5
trolling motor mount uses a one-piece plastic bracket with an adjustable strap. These are all "kick-up" mounting brackets. They help prevent damage if the transducer strikes an object while the boat is moving. If the transducer does "kick-up," the bracket can easily be pushed back into place without tools. Depending on your sonar unit's connectors, your transducer cable may also have the sonar unit's power cable attached to it. If that is the case, be sure to install the transducer first, before connecting the power cable to a power source. See the instructions later in this manual for connecting the power cable to a battery or other power supply. Read these instructions carefully before attempting the installation. Determine which of the mounting positions is right for your boat. Use extreme care if mounting the transducer inside the hull, because once it is epoxied into position, the transducer usually cannot be removed. Remember, the transducer installation is the most critical part of a sonar installation. Recommended Tools and supplies If you prefer the option of routing the cable through the transom, you will need a 5/8" drill bit. Each transom mount requires use of a high quality, marine grade above- or below-waterline caulking compound. NOTE: The following installation types also call for these recommended tools and required supplies (supplies are not included):

CAUTION: Clamp the transducer cable to transom near the transducer. This will help prevent the transducer from entering the boat if it is knocked off at high speed. Good location
Poor location Good location Good location Poor angle Good and poor transducer locations.
How low should you go? For most situations, you should install your Skimmer transducer so that its centerline is level with the bottom of the boat hull. This will usually give you the best combination of smooth water flow and protection from bangs and bumps.
Transducer centerline Transom
Hull bottom Align transducer centerline with hull bottom.
However, there are times when you may need to adjust the transducer slightly higher or lower. (The slots in the mounting brackets allow you to loosen the screws and slide the transducer up or down.) If you frequently lose bottom signal lock while running at high speed, the transducer may be coming out of the water as you cross waves or wakes. Move the transducer a little lower to help prevent this. If you cruise or fish around lots of structure and cover, your transducer may be frequently kicking up from object strikes. If you wish, you may move the transducer a little higher for more protection. There are two extremes you should avoid. Never let the edge of the mounting bracket extend below the bottom of the hull. Never let the bottom the face of the transducer rise above the bottom of the hull. Shoot-Thru-Hull vs. Transom Mounting In a shoot-thru-hull installation, the transducer is bonded to the inside of the hull with epoxy. The sonar "ping" signal actually passes through the hull and into the water. This differs from a bolt-thru-hull installa9
tion (often called simply "thru-hull"). In that case, a hole is cut in the hull and a specially designed transducer is mounted through the hull with a threaded shaft and nut. This puts the transducer in direct contact with the water. Typically, shoot-thru-hull installations give excellent high speed operation and good to excellent depth capability. There is no possibility of damage from floating objects. It can't be knocked off when docking or loading on the trailer. However, the shoot-thru-hull installation does have its drawbacks. First, some loss of sensitivity does occur, even on the best hulls. This varies from hull to hull, even from different installations on the same hull. This is caused by differences in hull lay-up and construction. Second, the transducer angle cannot be adjusted for the best fish arches. This can be a problem on hulls that sit with the bow high when at rest or at slow trolling speeds. Third, a transducer CAN NOT shoot through wood and metal hulls. Those hulls require either a transom mount or a thru-hull installation. Fourth, a Skimmer transducer with a built-in temp sensor will show only the temperature of the bilge, not the water surface temp. Follow the procedure listed in the shoot-thru-hull installation section at the end of this lesson to determine if you can satisfactorily shoot through the hull. Transom Transducer Assembly and Mounting The best way to install these transducers is to loosely assemble all of the parts first, place the transducer's bracket against the transom and see if you can move the transducer so that it's parallel with the ground. 1. Assembling the bracket. Press the two small plastic ratchets into the sides of the metal bracket as shown in the following illustration. Notice there are letters molded into each ratchet. Place each ratchet into the bracket with the letter "A" aligned with the dot stamped into 10

Orient the Skimmer with the nose facing the bow of the boat. To bow Epoxy transducer to hull.
WARNING: Use only the epoxy available from LEI. It has been formulated to work with these installation procedures. Other epoxy types may be too thin or may not cure to the right consistency for optimum transducer performance. 2. The epoxy consists of the epoxy itself and a hardener. Remove the two compounds from the package and place them on the paper plate. Thoroughly stir the two compounds together until the mixture has a uniform color and consistency. Do not mix too fast or bubbles will form in the epoxy. After mixing, you have 20 minutes to complete the installation before the epoxy becomes unworkable. Spread a thin layer of epoxy (about 1/16" or 1.5 mm thick) on the face of the transducer as shown in the previous figure. Make sure there are no 23
air pockets in the epoxy layer! Then, apply the remaining epoxy to the sanded area on the hull. 3. Press the transducer into the epoxy, twisting and turning it to force any air bubbles out from under the transducer face. Stop pressing when you bottom out on the hull. When you're finished, the face of the transducer should be parallel with the hull, with a minimum amount of epoxy between the hull and transducer. 4. Apply a weight, such as a brick, to hold the transducer in place while the epoxy cures. Be careful not to bump the transducer while the epoxy is wet. Leave the weight in place for a minimum of three hours. Allow the epoxy to cure for 24 hours before moving the boat. 5. After the epoxy has cured, route the cable to the sonar unit and it's ready to use.
The FishEasy 240 family can accept as many as two temperature sensors, which can be used to monitor the temperature of surface water, a live well or some other location. These units can accept an optional speed sensor for showing speed and distance traveled. However, you can only use one accessory at a time. If you would like to use a speed sensor and a temperature sensor at the same time, you will need a combination device. NOTE: The FishEasy 240 and FishEasy 240 Portable are packed with transducers containing built-in temp sensors. If you want a speed sensor or an additional temp sensor, see the Accessory Ordering Information in the back of this manual. If a second temp sensor is used, it must be the model TS-2U. This model has a fixed electronic "address" which designates it as the second of two temp sensors. Dual temperatures are displayed only on the Full Chart page. The Large Digital page will display only the primary temperature sensor.

Power connections for the FishEasy 240 sonar unit (direct battery connection shown).
If possible, keep the power cable away from other boat wiring, especially the engine's wires. This will provide the best isolation from electrical noise. The power cable has two wires, red and black. Red is the positive lead, black is negative or ground. Make sure to attach the inline fuse holder to the red lead as close to the power source as possible. For example, if you have to extend the power cable to the battery or power buss, attach one end of the fuse holder directly to the battery or power buss. This will protect both the unit and the power cable in the event of a short. It uses a 3-amp fuse. Caution: Do not use this product without a 3-amp fuse wired into the power cable! Failure to use a 3-amp fuse will void your warranty. This unit has reverse polarity protection. No damage will occur if the power wires are reversed. However, the unit will not work until the wires are attached correctly. Mounting the Sonar Unit: In-Dash, Bracket or Portable You can install the sonar unit on the top of a dash with the supplied bracket. This unit can be installed in a dash with the optional FM-6 indash adapter kit. The FM-6 kit includes an instruction sheet, part 9880147-631, which contains a template for cutting out the mounting hole. This document can be downloaded free from the www.eaglesonar.com web site. Bracket Installation Recommended tools for this job include: drill, 1" (25.4 mm) drill bit, screwdriver. Required supplies for this job include: high quality, marine grade above- or below-waterline caulking compound, three #10 stainless steel screws. Screw length and type should be suitable for the material on which you intend to mount the bracket. 32
Mount the unit in any convenient location, provided there is clearance when its tilted for the best viewing angle. You should also make sure there is enough room behind the unit to attach the power/transducer cable. (See the following drawings, which show the dimensions of a gimbal-mounted FishEasy 240 sonar unit.) Holes in the brackets base allow wood screw or through-bolt mounting. You may need to place a piece of plywood on the back side of thin panels to reinforce the panel and secure the mounting hardware. Drill a 1" (25.4 mm) hole in the dash for the power/transducer and accessory cables. The best location for this hole is immediately under the gimbal bracket location. This way, the bracket can be installed so that it covers the hole, holds the cables in position and results in a neat installation. Some customers, however, prefer to mount the bracket to the side of the cable hole it's a matter of personal preference.

PPP-12 Portable Power Pack with FishEasy 240 stowed for transport.
Turn the sonar unit on. If it doesn't work, make sure the battery terminals are making good contact against the battery contacts. Also check the wiring connections on the battery adapter. The red wire on the power cable should be attached to the red wire on the battery adapter and the power cable's black wire should be connected to the black wire on the battery adapter. If it still doesn't work, check the battery voltage. Most of the complaints we receive about portable units result from stale batteries. Make sure the ones you buy are fresh. In cold weather the efficiency of dry cell batteries drops with the temperature. We find it a good idea to have the sonar unit good and warm along with the batteries before we leave home. If the batteries do lose a charge, you can sometimes restore them by placing them in a warm room or car interior. A better way is to replace them with batteries that have been kept warm. WARNING: Never heat the batteries over an open flame or direct hot air onto them. A fire or explosion could result. 38
Portable Transducer Assembly Recommended tools for installation include a slotted screw driver and two adjustable wrenches. Assemble the transducer and bracket as shown in the following figure. Attach the transducer to the bracket with the supplied hardware. Make sure there is one washer on each side of the transducer, inside the bracket. Slide the other washer over the end of the bolt and thread the nut onto it. Screw the suction cup onto the bracket using the supplied screw and flat washer. Tie the nylon cord through the hole in the top of the bracket. When using this transducer, tie the other end of the nylon cord to the boat. This will help prevent the loss of the transducer if it comes off the boat.
Tie nylon cord here Suction cup Nut Washer Transducer Portable transducer assembly: rear view (left) and side view (right.) Screw

Clean the chosen area of the hull before attaching the suction cup. Locate the transducer on the hull as shown in the following figure. Don't 39
allow the bracket to extend below the hull, because water pressure against it can cause the suction cup to come off at speed. Moisten the cup, then press it onto the hull as firmly as possible. Tie the nylon cord to the boat and route the transducer cable to the sonar unit. Your portable sonar is now ready for use.

NOTE: You must hold the PWR key down for a countdown of five in order to turn the unit off. 2. MENU UP (menu up) 41
3. MENU DOWN (menu down) These keys appears in the manual text as MENU UP or MENU DOWN. Most of the time, the instructions require you to press either menu key, so the text simply uses the word MENU. Usually, when we say MENU, you can simply press the MENU UP key for consistency. This sonar unit has many features that are accessed with the menu keys. The MENU UP key moves up or forward through the menus, the MENU DOWN key moves down or backward. To see the first menu, simply press either MENU key. To see the other menus, press a MENU key repeatedly to cycle through the menu list. 4. UP and DOWN ARROWS These keys appear in the manual text as DOWN ARROW or UP ARROW. Use these keys to adjust virtually every feature and function on the sonar unit.

Memory

This unit has permanent memory that saves all user settings, even when power is removed. It does not require, nor does it use an internal backup battery, so you never have to worry about replacement batteries.
This unit uses menus to guide you through the various functions and features. Menu names and settings appear in the manual text as small capital letters like SENSITIVITY, which represents the Sensitivity menu. The menu keys access these features, allowing you to customize the unit to your particular needs and water conditions. All you have to do to leave one menu and enter another is press MENU repeatedly. If you ever get lost in the menus, simply press the PWR key. This clears the menus from the screen. Menus change depending on the mode the unit is in. Messages may appear in menu boxes or new menus can appear, depending on previous selections. 42

This screen shows a typical menu, the Scroll Speed menu.

Screen Display Modes or Pages
The FishEasy 240 has three screen display modes, or "Pages:" Full Chart page, Split Chart page and Large Digital page.
The FishEasy 240 Page menu lets you select among the display modes, or pages.
To switch from one page to another page, press MENU until the PAGE menu appears. Press UP ARROW or DOWN ARROW to select the desired 45
page. (The screen changes as you move through the menu.) When the page you want is selected, press PWR to clear the menu. Full Chart This shows all echoes scrolling across the full screen. This is the default page. The bottom signal scrolls across the screen from right to left. Depth scales on the right side of the screen make it easy to determine the depth of fish, structure, and other targets. The line at the top of the screen represents the surface. The bottom depth (as determined by the digital sonar) shows in the upper left corner.

Important Tip:

Your unit has the handy ability to quickly zoom in on any portion of the water column with just the touch of an arrow key. The Zoom Pan feature lets you rapidly move the zoomed area up and down to different depths. By "pointing" your zoom at different portions of the chart as it scrolls, you can get a good, close-up look at structure or cover below you. To use Zoom Pan, switch to a manual depth Range setting (see page 33) and turn on 2X or 4X Zoom. Then, simply press the UP ARROW or DOWN ARROW to pan up and down the water column. 49

Fig. 1

Fig. 2

Fig. 3

In 34 feet of water, with the Range set manually at 60 feet, the unit shows the entire water column in Fig. 1. To get a closer look, turn around and follow your wake to troll over the structure again. With the unit in 4X zoom, press the down arrow key to look at the six fish along the ledge, then press the up arrow to pan up the water column to see four game fish threatening a school of forage fish.
NOTE: Using the Zoom command while in auto Range mode will always enlarge the echoes near the bottom, because auto Range always keeps the bottom displayed in the lower portion of the screen. When you Zoom in manual Range mode, echoes are enlarged near the middle of the displayed range. For example, with a manual depth Range of 100 feet, your screen shows the water column from zero at the top of the screen to 50 feet in the middle to 100 feet at the bottom of the screen. Select 2X Zoom and the screen will show the water column from zero to 50 feet, with 25 feet shown in the middle of the screen. Select 4X Zoom and the screen shows the water column from 13 feet to about 39 feet, with 25 feet still in the middle of the screen. 50

Sensitivity

Sensitivity controls the unit's ability to pick up echoes. If you want to see more detail, try increasing the sensitivity, a little at a time. There are situations when too much clutter appears on the screen. Decreasing the sensitivity can reduce the clutter and show the strongest fish echoes, if fish are present. As you change the sensitivity setting, you can see the difference on the chart as it scrolls.

These figures show results of different sensitivity levels on the same location. Fig. 1: Sensitivity at 87 percent, determined by Auto Sensitivity. Typical of full auto mode. Fig. 2: Sensitivity set at 50 percent. Fig. 3: Sensitivity set at 20 percent. Fig. 4: Sensitivity set at 100 percent.

To change the Grayline level, press MENU until the GRAYLINE menu appears. Press UP ARROW to increase the level or press DOWN ARROW to decrease it. The percentage of Grayline in use shows in this menu. Echoes scrolling onto the screen will also show the effects of the Grayline change. If you reach the maximum or minimum level, a tone sounds alerting you to the limits. Press PWR to clear the menu.

Fish I.D.

The Fish I.D. feature identifies targets that meet certain conditions as fish. The microcomputer analyses all echoes and eliminates surface clutter, thermoclines and other signals that are undesirable. In most instances, remaining targets are fish. The Fish I.D. feature displays symbols on the screen in place of the actual fish echoes. There are three symbol sizes: small, medium, and large. These show the relative size between targets. In other words, it 55
displays a small fish symbol when it thinks a target is a small fish, a medium fish symbol on a larger target and so forth.

Fish I.D. symbol

Fish arches
Fish I.D. is an easier way for a sonar novice to recognize a fishy signal return when he sees it. However, locating fish by symbol only has some limitations. Your sonar unit's microcomputer is sophisticated, but it can be fooled. It can't distinguish between fish and other suspended objects such as trotlines, turtles, submerged floats, air bubbles, etc. Individual tree limbs extending outward from a group of limbs are the hardest objects for the Fish I.D. feature to distinguish from fish. To see what's under your boat in maximum detail, we recommend you turn off Fish I.D. and begin learning to interpret fish arches. You may see Fish I.D. symbols on the screen when actually, there are no fish. The reverse is also true Fish I.D. can actually miss fish that are present. Does that mean Fish I.D. is broken? No the feature is simply interpreting sonar returns in a specific way to help take some of the work 56

out of reading the screen. Remember: Fish I.D. is one of the many tools we provide so you can analyze your sonar returns for maximum fish finding information. This and other features can help you successfully "see" beneath the boat under varied water and fishing conditions. So, practice with the unit in both the Fish I.D. mode and without to become more familiar with the feature. The default for Fish I.D. is off. Fish I.D. is most handy when you're in another part of the boat or performing some task that prevents you from watching the sonar screen. Then, you can turn on Fish I.D. and the audible fish alarm. When that lunker swims under your boat, you'll hear it! Fish I.D. can also be useful when you want to screen out some of the sonar detail gathered by your unit. For example, it can help cut through the clutter of suspended bubbles caused by wave action or boat wakes. To turn Fish I.D. on, press MENU until the FISH ID menu appears. Press UP ARROW to select ON, then press PWR. To turn it back off, repeat the above steps, but press DOWN ARROW to select OFF.

Alarms

The sonar unit has two different types of alarms, fish and depth. Fish Alarm The Fish Alarm sounds a tone when a fish symbol appears on the screen. The default setting is on, but the Fish I.D. feature must be turned on for fish alarms to work. To turn Fish I.D. on, press MENU until the FISH ID menu appears. Press UP ARROW to select ON, then press PWR. To turn off the fish alarm without turning off fish symbols, press MENU DOWN until FISH ALARM appears. Press DOWN ARROW to select OFF, then press PWR to clear the menu. Repeat the above steps to turn the alarm back on, but press UP ARROW to select ON before clearing the menu.

Fish Alarm menu.

Depth Alarms The depth alarms are triggered only by the bottom signal. No other echoes will activate these alarms. The depth alarms consist of a shallow and a deep alarm. The shallow alarm sounds an alarm tone when the bottom goes shallower than the alarm's setting. The deep alarm sounds a tone when the bottom goes deeper than its setting. Both alarms adjust the same way, although through different menus. 63
Shallow Alarm To set the shallow alarm depth, press MENU DOWN repeatedly until SHALLOW ALARM appears.

Press UP ARROW to silence the alarm. This turns the alarm sound off until the shallow alarm is triggered again. To turn the alarm off, press MENU DOWN repeatedly until SHALLOW ALARM appears. Press DOWN ARROW until the words OFF FEET appear, then press PWR to clear the menu. Deep Alarm To set the deep alarm depth, press MENU DOWN repeatedly until DEEP ALARM appears. Press UP ARROW to increase the deep alarm's depth setting or press DOWN ARROW to decrease it. The number in the deep alarms menu box 64
shows the current deep alarm setting. When the number reaches the desired setting, press PWR to clear the menu. When the bottom depth goes deeper than the alarms setting, an alarm tone sounds and a message box appears on the screen.

Limit Search
The Limit Search command helps you maintain maximum chart detail when you are moving fast in deep water (about 200 feet). When turned on, Limit Search prevents the digital sonar from over-riding the sonar chart's depth range setting. Limit Search does this by preventing the digital sonar from slowing down the ping speed as it automatically searches for and tracks the bottom. The default setting is off, and this should fit most freshwater fishing situations. High boat speed and slow ping speed (caused by the deeper bottom) can reduce the screen refresh rate. This in turn can reduce the amount of detail seen on the sonar chart. Try this command only if you are in deep water, traveling at high speed, and notice a reduction in detail on the sonar chart. When Limit Search is turned on, the digital sonar will limit its search for the bottom to the depth range you have set for the sonar chart. NOTE: Turning Limit Search on can cause the digital sonar to lose the bottom in some situations. The digital depth will flash if that occurs. 73
The sonar chart must be in manual depth range mode to use the Limit Search command. To switch from auto depth range to manual, press MENU until the RANGE menu appears. Use the arrow keys to select the desired range. When you're finished, press PWR to clear the menu from the display. Next, press MENU DOWN until the CHART SETUP menu appears, then press UP ARROW to enter the list of Chart Setup commands, where the LIMIT SEARCH menu appears. Press UP ARROW to turn it on and press PWR to clear the menu.

Introduction

Thank you for buying an Eagle sonar! Your unit is a high-quality sonar designed for both professional and novice fishermen. All Eagle sonars have an automatic mode that finds and displays the bottom, fish, underwater structure and more right out of the box. All you have to do is press the on (PWR) key. However, if you want to fine-tune your unit, press the MENU UP key. The FishEasy 2 family has several powerful features you can control by scrolling through easy-to-use menus with the arrow and menu keys. To get started with your Eagle sonar, first read the installation section. It contains instructions for mounting the sonar unit, the transducer and any optional accessories, such as a speed sensor. Following recommended installation practices will pay off in optimum performance of your Eagle sonar. Improper installation can cause problems down the road, especially if the transducer is badly mounted. After you've read the installation instructions, install the unit and accessories. Then, read the rest of the manual. The more you know about your sonar, the better it will work for you. Take advantage of the Simulator feature. It allows you to practice operating your sonar before you get it in the water. And when you finally head for your favorite fishing hole, take this manual along for reference.

Tools: two adjustable wrenches, drill, #20 (0.161") drill bit, flat-head screwdriver (for mounting screws and their pilot holes). Supplies: four, 1" long, #12 stainless steel slotted wood screws.
Single-frequency trolling motor installations
Tools: two adjustable wrenches, flat-head screwdriver. Supplies: plastic cable ties.
Shoot-through hull installations
Tools: these will vary depending on your hull's composition. Consult your boat dealer or manufacturer. Supplies: 100 grit sandpaper, good quality epoxy adhesive. Selecting a Transducer Location 1. The transducer must be placed in a location that has a smooth flow of water at all times. If the transducer is to be mounted inside the hull, then the chosen location must be in the water at all times. If the transducer is not placed in a smooth flow of water, interference caused by bubbles and turbulence will show on the sonar's display in the form of random lines or dots whenever the boat is moving. NOTE: Some aluminum boats with strakes or ribs on the outside of the hull create large amounts of turbulence at high speed. These boats typically have large outboard motors capable of propelling the boat at speeds faster than 35 mph. Typically, a good location on aluminum boats is between the ribs closest to the engine. 2. The transducer should be installed with its face pointing straight down, if possible. 3. If the transducer is mounted on the transom, make sure it doesn't interfere with the trailer or hauling of the boat. Also, don't mount it closer than approximately one foot from the engine's lower unit. This will prevent cavitation (bubble) interference with propeller operation. 4. If possible, route the transducer cable away from other wiring on the boat. Electrical noise from engine wiring, bilge pumps and aerators can be displayed on the sonar's screen. Use caution when routing the transducer cable around these wires. 4
CAUTION: Clamp the transducer cable to transom near the transducer. This will help prevent the transducer from entering the boat if it is knocked off at high speed.

Good location

Poor location Good location
Good location Poor angle Good and poor transducer locations.
How low should you go? For most situations, you should install your Skimmer transducer so that its centerline is level with the bottom of the boat hull. This will usually give you the best combination of smooth water flow and protection from bangs and bumps.

Transom Transom

Transducer centerline

Hull bottom

Align transducer centerline with hull bottom. A dual frequency transducer is shown at left and a single frequency transducer at right.

However, there are times when you may need to adjust the transducer slightly higher or lower. (The slots in the mounting brackets allow you to loosen the screws and slide the transducer up or down.) If you frequently lose bottom signal lock while running at high speed, the transducer may be coming out of the water as you cross waves or wakes. Move the transducer a little lower to help prevent this. If you cruise or fish around lots of structure and cover, your transducer may be frequently kicking up from object strikes. If you wish, you may move the transducer a little higher for more protection. 5
There are two extremes you should avoid. Never let the edge of the mounting bracket extend below the bottom of the hull. Never let the bottom the face of the transducer rise above the bottom of the hull. Shoot-thru-hull vs. Transom Mounting Typically, shoot-thru-hull installations give excellent high speed operation and good to excellent depth capability. There is no possibility of damage from floating objects. It can't be knocked off when docking or loading on the trailer. However, the shoot-thru-hull installation does have its drawbacks. First, some loss of sensitivity does occur, even on the best hulls. This varies from hull to hull, even from different installations on the same hull. This is caused by differences in hull lay-up and construction. Second, the transducer angle cannot be adjusted for the best fish arches. This can be a problem on some hulls that sit with the bow high when at rest or at slow trolling speeds. Follow the procedure listed in the shoot-thru-hull installation section at the end of this lesson to determine if you can satisfactorily shoot through the hull. TRANSOM TRANSDUCER ASSEMBLY AND MOUNTING The best way to install these transducers is to loosely assemble all of the parts first, place the transducer's bracket against the transom and see if you can move the transducer so that it's parallel with the ground. The following instructions sometimes vary depending on the mounting bracket that came with your transducer. Single frequency Skimmers come with a one-piece stainless steel bracket, while dual frequency Skimmers come with a two-piece plastic mounting bracket. Use the set of instructions that fits your model. 1. Assembling the bracket. A. One-piece bracket: Press the two small plastic ratchets into the sides of the metal bracket as shown in the following illustration. Notice there are letters molded into each ratchet. Place each ratchet into the bracket with the letter "A" aligned with the dot stamped into the metal bracket. This position sets the transducer's coarse angle adjustment for a 14 transom. Most outboard and stern-drive transoms have a 14 angle.

Align plastic ratchets in bracket.
B. Two-piece bracket: Locate the four plastic ratchets in the transducer's hardware package. Press two ratchets into the sides of the plastic bracket and two on either side of the transducer as shown in the following illustrations. Notice there are letters molded into each ratchet. Place the ratchets into the bracket with the letter "A" aligned with the alignment mark molded into the bracket. Place the ratchets onto the transducer with the letter "A" aligned with the 12 o'clock position on the transducer stem. These positions set the transducer's coarse angle adjustment for a 14 transom. Most outboard and stern-drive transoms have a 14 angle.

2. Aligning the transducer on the transom. A. One-piece bracket: Slide the transducer between the two ratchets. Temporarily slide the bolt though the transducer assembly and hold it against the transom. Looking at the transducer from the side, check to see if it will adjust so that its face is parallel to the ground. If it does, then the "A" position is correct for your hull. If the transducer's face isn't parallel with the ground, remove the transducer and ratchets from the bracket. Place the ratchets into the holes in the bracket with the letter "B" aligned with the dot stamped in the bracket. Reassemble the transducer and bracket and place them against the transom. Again, check to see if you can move the transducer so it's parallel with the ground. If you can, then go to step 3A. If it doesn't, repeat step 2A, but use a different alignment letter until you can place the transducer on the transom correctly.

Ratchets

Insert bolt and check transducer position on transom.
B. Two-piece bracket: Assemble the transducer and bracket as shown in the following figure. Temporarily slide the bolt though the transducer assembly but don't tighten the nut at this time. Hold the assembled transducer and bracket against the transom. Looking at the transducer from the side, check to see if it will adjust so that its face is parallel to the ground. If it does, then the "A" positions are correct for your hull. If the transducer's face isn't parallel with the ground, remove and disassemble the transducer and ratchets. Place the ratchets into the bracket holes with the letter "B" aligned with the bracket alignment mark. Place them on the transducer aligned with the 12 o'clock position on the transducer stem. Reassemble the transducer and bracket and place them against the transom. Again, check to see if you can move the transducer so it's

parallel with the ground. If you can, then go to step 3B. If it doesn't, repeat step 2B, but use a different alignment letter until you can place the transducer on the transom correctly.

B. Two-piece bracket: Once you determine the correct position for the ratchets, assemble the transducer as shown in the figure in step 2B. Don't tighten the lock nut at this time. 4. Drilling mounting holes. Hold the transducer and bracket assembly against the transom. The transducer should be roughly parallel to the ground. The transducer's centerline should be in line with the bottom of the hull. Don't let the bracket extend below the hull! 9
Mark the center of each slot for the mounting screw pilot holes. You will drill one hole in the center of each slot. Drill the holes. For the one-piece bracket, use the #29 bit (for the #10 screws). For the two-piece bracket, use the #20 bit (for the #12 screws).

Transom

5. Attaching transducer to transom. A. One-piece bracket: Remove the transducer from the bracket and re-assemble it with the cable passing through the bracket over the bolt as shown in the following figures.
For single frequency Skimmer, route cable over bolt and through bracket. Side view shown at left and seen from above at right.
Both bracket types: Attach the transducer to the transom. Slide the transducer up or down until it's aligned properly with the bottom of the hull as shown in the preceding and following figures. Tighten the bracket's mounting screws, sealing them with the caulking compound. Adjust the transducer so that it's parallel to the ground and tighten the nut until it touches the outer washer, then add 1/4 turn. Don't over tighten the lock nut! If you do, the transducer won't "kick-up" if it strikes an object in the water.

Speed Sensor Installation If you wish to purchase an optional sensor for your unit, refer to the accessory ordering information inside the back cover of this manual. The following instructions describe how to install the speed sensor. Recommended tools for this job include: drill, 5/8"drill bit, 1/8" drill bit for pilot holes, screwdriver. Required supplies for this job include: four #8 stainless steel wood screws (3/4" long), high quality, marine grade aboveor below-waterline caulking compound. First find a location on the boat's transom where the water flow is smoothest. Don't mount the sensor behind strakes or ribs. These will disturb the water flow to the speed sensor. Make sure the sensor will remain in the water when the boat is on plane. Also make sure the location doesn't interfere with the boat's trailer. Typically, the sensor is mounted about one foot to the side of the transom's centerline. Once you've determined the proper location for the unit, place the sensor on the transom. The bottom of the bracket should be flush with the hull's bottom. Using the sensor as a template, mark the hull for the screws' pilot holes. Drill four 1/8" holes, one in each end of the slots. Mount the sensor to the hull using #8 stainless steel wood screws (not included). Use a high quality, marine grade above- or below-waterline caulking compound to seal the screws. Make sure the sensor is flush with the bottom of the hull and tighten the screws.

Bottom of hull Speed sensor mounting configuration: side view (left) and rear view (right.)
If the base of the transom has a radius, fill the gap between the transom and the sensor with the caulking compound. This will help ensure a smooth water flow. Route the sensor's cable through or over the transom to the sonar unit. If you need to drill a hole in the transom to pass the connector through, the required hole size is 5/8". Caution: If you drill a hole in the transom for the cable, make sure it is located above the waterline. After installation, be sure to seal the hole with the same marine grade above- or below-waterline sealant used for the screws. The sensor is now ready for use. Connect the sensor to the accessory socket on the back of the unit. If you have any questions concerning the installation of the sensor, please contact your local boat dealer. POWER CONNECTIONS (permanent mount units only) The unit works from a 12-volt battery system. You can attach the power cable to your boat's accessory or power buss (or directly to the battery). If you use an accessory buss but have problems with electrical interference, attach the power cable directly to the battery. If the cable is not long enough, splice #18 gauge wire onto it.

Power connections for the FishEasy 2 family sonar units (direct battery connection shown).
If possible, keep the power cable away from other boat wiring, especially the engine's wires. This will provide the best isolation from electrical noise. The power cable has two wires, red and black. Red is the positive lead, black is negative or ground. Make sure to attach the inline fuse holder to the red lead as close to the power source as possible. For example, if you have to extend the power cable to the battery or power buss, attach one end of the fuse holder directly to the battery or 20
power buss. This will protect both the unit and the power cable in the event of a short. It uses a 3-amp fuse. CAUTION: Do not use this product without a 3-amp fuse wired into the power cable! Failure to use a 3-amp fuse will void your warranty. This unit has reverse polarity protection. No damage will occur if the power wires are reversed. However, the unit will not work until the wires are attached correctly. MOUNTING THE SONAR UNIT: In-Dash, Bracket or Portable You can install the sonar unit on the top of a dash with the supplied bracket. It can also be installed in the dash with an optional FM-4 mounting kit. In-Dash Installation The following figure shows dimensions for in-dash mounting. The indash adapter kit includes a template for cutting the mounting hole and complete installation directions on instruction sheet 988-0147-44.

If you use the supplied gimbal bracket, you may be interested in the optional GBSA-1 swivel bracket kit. This converts the unit's gimbal bracket to a swivel mount which can be used on the dash or overhead 21
mounting positions. Installation instructions for the in-dash and swivel mounting kits are supplied with the adapter kits. Bracket Installation Mount the unit in any convenient location, provided there is clearance when its tilted for the best viewing angle.

It may be necessary to place a piece of plywood on the back side of thin panels to reinforce the panel. Make sure there is enough room behind the unit to attach the power and transducer cables. Drill a 1-inch (25.4 mm) hole in the dash for the power and transducer cables. The best location for this hole is immediately under the gimbal bracket location. This way, the bracket can be installed so that it covers the hole, holds the cables in position and results in a neat installation. Some customers, however, prefer to mount the bracket to the side of the cable hole it's a matter of personal preference. After drilling the hole, pass the transducer connector up through the hole from under the dash. Drop the power cable's bare-wire end down though the hole from the top. If you wish, you can fill in the hole around the cables with a good marine caulking compound. (Some marine dealers stock cable hole covers to conceal the opening.) No matter what type of installation you prefer, 22
be sure to leave enough slack in the cables to allow tilting or swiveling the unit. If you choose to fill in the hole, be sure to position the cables against the rear edge of the hole as you apply the fill material. Before positioning the bracket, be sure to hold the cables against the rear edge of the hole. Then, slide the bracket over the hole and butt the rear of the bracket base firmly against the cables, thus pinning them in place against the side of the hole. Finally, fasten the bracket to the dash. Attach the unit to the gimbal bracket using the supplied gimbal knobs and washers. Slide the rubber washers onto the gimbal knobs then loosely screw the knobs into their sockets. Slide the unit into the bracket with the rubber washers to the outside of the bracket arms. Tilt the unit to the desired viewing angle and tighten the knobs finger tight Portable Sonar Installation Like many Eagle products, the FishEasy 2 sonar family is capable of portable operation by using the optional PPP-13 portable power pack. In fact, the FishEasy 2 Portable package includes the PPP-13 and the transducer necessary for portable use. The power pack and portable or floating transducers expand the uses for your sonar. You can use your FishEasy 2 or FishEasy 2 Portable on your boat or take it to the dock, on a float tube, on an ice fishing trip or use it as a second sonar in a friend's boat. The PPP-13 package includes the power pack, battery adapter and a portable transducer. Batteries are not included. The power pack has a storage compartment for the portable transducer. The pack can be used with eight "D" cell alkaline batteries or an optional sealed, rechargeable battery. To use the portable power pack, you simply install the batteries and then attach the sonar unit to the power pack's bracket. Plug in the power and transducer cables and you're ready to fish. Attach the sonar unit to the bracket with the supplied washers and knobs. Installing the Power Pack Recommended tools for installation include a slotted screw driver and two adjustable wrenches. The following figure shows the proper arrangement for the washers.

For a secure portable mount, attach the unit to the portable power pack's gimbal bracket using the supplied gimbal knobs and washers as shown above.
Installing the Batteries Release the latch on the front of the battery case. Open the compartment and install either an optional rechargeable battery or eight "D" cell batteries into the adapter. For the longest life, we recommend you use alkaline batteries. After installing the batteries, close the case and plug the sonar unit's power cable into the socket on the battery case. Turn the sonar unit on. If it doesn't work, make sure the battery terminals are making good contact against the battery contacts. Also check the wiring connections on the D-cell battery adapter. The red wire on the power cable should be attached to the red wire on the D-cell battery adapter and the power cable's black wire should be connected to the black wire on the D-cell battery adapter. If it still doesn't work, check the battery voltage. Most of the complaints we receive about portable units result from stale batteries. Make sure the ones you buy are fresh. Always remove batteries from the battery compartment before storing the unit because dead batteries can leak and corrode the contacts.
"D" cell battery
Install batteries in power case battery adapter.
In cold weather the efficiency of dry cell batteries drops with the temperature. We find it a good idea to have the sonar unit good and warm along with the batteries before we leave home. If the batteries do lose a charge, you can sometimes restore them by placing them in a warm room or car interior. A better way is to replace them with batteries that have been kept warm. WARNING: Never heat the batteries over an open flame or direct hot air onto them. A fire or explosion could result. Portable Transducer Assembly Assemble the transducer and bracket as shown in the following figure. Attach the transducer to the bracket with the supplied hardware. Make sure there is one washer on each side of the transducer, inside the bracket. Slide the other washer over the end of the bolt and thread the nut onto it. Screw the suction cup onto the bracket using the supplied screw and flat washer. Tie the nylon cord through the hole in the top of the bracket. When using this transducer, tie the other end of the nylon cord to the boat. This will help prevent the loss of the transducer if it comes off the boat. 25

Your unit has the handy ability to quickly zoom in on any portion of the water column with just the touch of an arrow key. The Zoom Pan feature lets you rapidly move the zoomed area up and down to different depths. By "pointing" your zoom at different portions of the chart as it scrolls, you can get a good, close-up look at structure or cover below you. To use Zoom Pan, switch to a manual depth Range setting (see page 33) and turn on 2X or 4X Zoom. Then, simply press the UP ARROW or DOWN ARROW to pan up and down the water column.

Fig. 1 Fig. 2 Fig. 3

In 34 feet of water, with the Range set manually at 60 feet, the unit shows the entire water column in Fig. 1. To get a closer look, turn around and follow your wake to troll over the structure again. With the unit in 4X zoom, press the down arrow key to look at the six fish along the ledge, then press the up arrow to pan up the water column to see four game fish threatening a school of forage fish.
NOTE: Using the Zoom command while in auto Range mode will always enlarge the echoes near the bottom, because auto Range always keeps the bottom displayed in the lower portion of the screen. 34
When you Zoom in manual Range mode, echoes are enlarged near the middle of the displayed range. For example, with a manual depth Range of 100 feet, your screen shows the water column from zero at the top of the screen to 50 feet in the middle to 100 feet at the bottom of the screen. Select 2X Zoom and the screen will show the water column from zero to 50 feet, with 25 feet shown in the middle of the screen. Select 4X Zoom and the screen shows the water column from 13 feet to about 39 feet, with 25 feet still in the middle of the screen. SENSITIVITY Sensitivity controls the unit's ability to pick up echoes. If you want to see more detail, try increasing the sensitivity, a little at a time. There are situations when too much clutter appears on the screen. Decreasing the sensitivity can reduce the clutter and show the strongest fish echoes, if fish are present. As you change the sensitivity setting, you can see the difference on the chart as it scrolls.

These figures show results of different sensitivity levels on the same location. Fig. 1: Sensitivity at 87 percent, determined by Auto Sensitivity. Typical of full auto mode. Fig. 2: Sensitivity set at 50 percent. Fig. 3: Sensitivity set at 20 percent. Fig. 4: Sensitivity set at 100 percent.
You can change the sensitivity level whether you are in Auto Sensitivity mode or Manual Sensitivity mode. The adjustment method works the same in both modes, but it gives you slightly different results. Adjusting sensitivity in Auto Sensitivity Mode is similar to manually adjusting a car's speed with the accelerator pedal while cruise control is on. You can tell the car to run faster, but when you let off the gas the cruise control automatically keeps you from running slower than the minimum speed setting. In your unit, auto mode will let you increase sensitivity to 100 percent, but the unit will limit your minimum setting. This prevents you from turning sensitivity down too low to allow automatic bottom tracking. When you change the setting with auto turned on, the unit will continue to track the bottom and make minor adjustments to the sensitivity level, with a bias toward the setting you selected. Adjusting sensitivity in Manual Sensitivity Mode is similar to driving a car without cruise control you have complete manual control of the car's speed. In your unit, manual mode allows you to set sensitivity at 100 percent (maximum) or zero percent (minimum.) Depending on water and bottom conditions, the bottom signal may completely disappear from the screen when you reduce sensitivity to about 20 percent or less! Try adjusting sensitivity in both auto and manual modes to see how they work.

FISHREVEAL When displaying actual sonar returns, the FishReveal feature helps show fish targets hidden by surface clutter, thermoclines, weed beds and other cover with 10 levels of gray tones. Normal operation (with FishReveal turned off) shows the weakest echoes as black and the strongest in light gray. Since all weak echoes are black, fish arches show boldly against the white background. The drawback is that all weak echoes such as thermoclines are also accentuated. This can make it hard to distinguish fish signals inside thermoclines or other cover.
At left FishReveal menu screen. The feature is off and screen is in normal mode. Right, Fish Reveal is on, in standard mode.
There are two FishReveal modes: standard and inverted. In standard mode, the weakest echoes are white and the strongest echoes are black. Echoes in between vary in gray in proportion to their signal strength. In Inverted FishReveal mode, the weakest echoes are black and the strongest echoes are white. Again, echoes in between vary in gray in proportion to their signal strength. In all modes, the Grayline control determines the range for black to white.
At left, standard FishReveal mode. Right, Inverted Fish Reveal mode.
To turn FishReveal on, press MENU DOWN until CHART SETUP appears, then press UP ARROW. Press MENU DOWN until CHART MODE appears. Press DOWN ARROW to select the desired FishReveal mode. Press PWR to clear the menu. To return to normal operation, repeat the above steps, but select NORMAL before clearing the menu. CHART SCROLL SPEED and HYPERSCROLL The rate that echoes scroll across the screen is called the chart scroll speed. The default for this unit is 60 percent; we recommend that you leave the scroll speed set there for virtually all fishing conditions. However, you might consider experimenting with chart speed when you are stationary or drifting very slowly. You may sometimes achieve better images as you slow down the chart speed to match how fast you are moving across the bottom. Switching to a scroll speed faster than 60 percent can be helpful when running at high speed. Any setting greater than 60 switches the unit to HyperScroll. This feature scrolls the echoes at an extremely high rate of speed, giving you the maximum screen update. 41

Noise Reject menu.

The ASP feature has four settings Off, Low, Medium and High. When first turned on, noise rejection is set on low. If you have high noise levels, try using the medium or high ASP setting. However, if you are having trouble with noise, we suggest that you take steps to find the interference source and fix it, rather than continually using the unit with the high ASP setting. There are times when you may want to turn ASP off. This allows you to view all incoming echoes before they are processed by the ASP feature. To change the ASP setting, press MENU DOWN until NOISE REJECT appears. Use the up and down arrow keys to select the desired setting, then press PWR to clear the menu.

ALARMS

The sonar unit has two different types of alarms, fish and depth. Fish Alarm The Fish Alarm sounds a tone when a fish symbol appears on the screen. The default setting is on, but the Fish I.D. feature must be turned on for fish alarms to work. 43
To turn Fish I.D. on, press MENU until the FISH ID menu appears. Press UP ARROW to select ON, then press PWR. To turn off the fish alarm without turning off fish symbols, press MENU DOWN until FISH ALARM appears. Press DOWN ARROW to select OFF, then press PWR to clear the menu. Repeat the above steps to turn the alarm back on, but press UP ARROW to select ON before clearing the menu.

Fish Alarm menu.

Depth Alarms The depth alarms are triggered only by the bottom signal. No other echoes will activate these alarms. The depth alarms consist of a shallow and a deep alarm. The shallow alarm sounds an alarm tone when the bottom goes shallower than the alarm's setting. The deep alarm sounds a tone when the bottom goes deeper than its setting. Both alarms adjust the same way, although through different menus. Shallow Alarm To set the shallow alarm depth, press MENU DOWN repeatedly until SHALLOW ALARM appears.

Shallow Alarm menu.

Press UP ARROW to increase the shallow alarm's depth setting or press DOWN ARROW to decrease it. The number in the shallow alarms menu box shows the current shallow alarm setting. When the number reaches the desired setting, press PWR to clear the menu. When the bottom depth goes shallower than the alarms setting, an alarm tone sounds and a message box appears on the screen. Press UP ARROW to silence the alarm. This turns the alarm sound off until the shallow alarm is triggered again. To turn the alarm off, press MENU DOWN repeatedly until SHALLOW ALARM appears. Press DOWN ARROW until the words OFF FEET appear, then press PWR to clear the menu. Deep Alarm To set the deep alarm depth, press MENU DOWN repeatedly until DEEP ALARM appears. Press UP ARROW to increase the deep alarm's depth setting or press DOWN ARROW to decrease it. The number in the deep alarms menu box shows the current deep alarm setting. When the number reaches the desired setting, press PWR to clear the menu. When the bottom depth goes deeper than the alarms setting, an alarm tone sounds and a message box appears on the screen.
