True bottom

Second bottom

Manual range setting

Example of a second bottom signal. Unit is in 30 feet of water, with range set at 80 feet and sensitivity set at 87 percent.
2. Next, take the transducer out of the water and place it in the water in the sump of the boat, face down. (The transducer face is shown in the figure on the following page.) Notice how the signal strength decreases. The second bottom signal will probably disappear and the bottom signal intensity will likely decrease. 22
3. Now move the transducer around to find the best location with the strongest possible bottom signal. If you find a spot with an acceptable bottom signal, mark the location and move on to step 4. If you can't get an acceptable bottom signal, try turning up the sensitivity by three or five keystrokes and then move the transducer around once more. If you find a spot that works, mark it and move on to step 4. If you have to turn up sensitivity by more than five keystrokes to get a good signal, the transducer should be mounted on the outside of the hull. This is especially true if you have to turn sensitivity all the way up to get a decent bottom signal. 4. Most people can get good results by following steps 1 through 3, so this step is optional. If you want to make an extra effort to be absolutely sure that your selected location will work under all conditions, make a test run with the boat on plane and observe the bottom signal. You'll need to figure some way to prop the transducer into position while you make your test run. (A brick or two might be sufficient to hold it in place.) 5. When you're satisfied with a location, mark it and proceed with the installation. Shoot-thru-hull Installation If you are installing the transducer on a hull with floatation material sandwiched within the hull, refer to the text "Hulls With Flotation Materials" beginning on page 20. 1. Make sure the area is clean, dry and free of oil or grease, then sand both the inside surface of the hull and the face of the transducer with 100 grit sandpaper. The sanded hull area should be about 1-1/2 times the diameter of the transducer. The surface of the hull must be flat so the entire transducer face is in contact with the hull prior to bonding. After sanding, clean the hull and transducer with rubbing alcohol to remove any sanding debris.

Spread epoxy here

Sand this surface (unit's face) 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 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. 24
Speed/Temperature Sensors
Optional Speed Sensor Installation If you wish to purchase an optional or additional speed sensor for your unit, visit our website, www.lowrance.com, or 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, 7/8" 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 above- or below-waterline sealant. 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 sealant to seal the screws. Make sure the sensor is flush with the bottom of the hull and tighten the screws.

To NMEA 2000 network port To sonar unit's Network socket Lowrance unit direct connection to NMEA 2000 buss.
As soon as the unit is connected to the network, it will begin receiving shared information. Please note the buss must be powered to operate. (See instructions in this section for more on powering NMEA 2000 buss.) NMEA 0183 Wiring (Data cable) To exchange NMEA 0183 data, this unit has one NMEA 0183 version 2.0 communication port. Com port one (Com-1) can be used to receive NMEA format GPS data. The com port can also transmit NMEA format GPS data to another device. 32
The four wires for the com port are combined with the Power Supply cable and NMEA 2000 Power cable to form the power/data cable (shown earlier). Com-1 uses the yellow wire to transmit, the orange wire to receive and the shield wire for signal ground. Your unit does not use the blue wire.

Mounting the Unit: Bracket or In-Dash
You can install the unit on top of a dash with the gimbal bracket. It can also be installed in the dash or mounted on a portable power supply. 34
If you use the supplied bracket, you may be interested in the optional R-A-M bracket mounting system. This converts the unit's gimbal bracket to a swivel mount, which can be used on the dash or overhead mounting positions.
Optional R-A-M mounting system.
Bracket Installation Mount the unit in any convenient location, provided there is clearance behind the unit when it's tilted for the best viewing angle. You should also make sure there is enough room behind the unit to attach the power, transducer and GPS antenna/receiver module cables. (A drawing on the next page shows the dimensions of a gimbal-mounted unit.) Holes in the bracket's base allow wood screw or through-bolt mounting. You may need to place a piece of plywood on the back side of thin fiberglass panels to reinforce the panel and secure the mounting hardware.

Frequency (Change Transducer Frequency)
A dual-frequency transducer operates with both 200 kHz and 50 kHz. The 200 kHz frequency has a 12 cone angle and the 50 kHz frequency has a 35 cone angle. The default frequency is 200 kHz, which is best for use in shallow water (about 300 feet or less). This frequency is the best choice for about 80 percent of the fresh and salt water sport fishing applications. When you get into very deep salt water, 300 to 500 feet or deeper, the 50 kHz frequency is the best choice. The 200 kHz transducer will give you better detail and definition, but less depth penetration. The 50 kHz transducer will give you greater depth penetration, but a little less detail and less definition. (Remember, all sonar units typically read deeper in fresh water than in salt water.) There is a common exception to these rules of thumb. Some fishermen on freshwater lakes (or the ocean) using downriggers like to see them 69

on the sonar. In many of those cases, you'll see a 50 kHz transducer frequency in use because the wider cone angle lets them watch the bait.

The Satellite Status Page shows the quality and accuracy of the current satellite lock-on and position calculation. WARNING: Do not begin navigating with this unit until the numbers have stopped flashing!
The Satellite Status Page.
This screen shows a graphical illustration of the satellites that are in view. Each satellite is shown on the circular chart relative to your position. The point in the center of the chart is directly overhead. The small inner ring represents 45 above the horizon and the large ring represents the horizon. North is at the top of the screen. You can use this to see which satellites are obstructed by obstacles in your immediate area if the unit is facing north. The GPS receiver is tracking satellites represented by a blue bar. The receiver hasn't locked onto a satellite if the number is a lighter shade, therefore it isn't being used to solve the position. Beneath the circular graph are the bar graphs, one for each satellite in view. Since the unit has twelve channels, it can dedicate one channel per visible satellite. The taller the bar on the graph, the better the unit is receiving the signals from the satellite. The "Estimated Position Error" (horizontal position error) shown in the upper left corner of the screen is the expected error from a benchmark location. In other words, if the EPE shows 50 feet, then the position shown by the unit is estimated to be within 50 feet of the actual location. This also gives you an indicator of the fix quality the unit currently has. The smaller the position error number, the better (and more accurate) the fix is. 99

Navigate To a Waypoint

You can select any waypoint visible on the Map Page with the cursor, then use the Navigate to Cursor command, which will be covered later in this section.

Set Man Overboard (MOB) Waypoint
One of boating's most terrifying events is having a friend or family member fall overboard. It's particularly dangerous at night or if you're out of sight of land. Of course, the first thing to do is remain calm and use all standard safety procedures to rescue the person. This unit has a man overboard feature that shows navigation data to the location where the feature was activated. To activate it, press the ZOUT and ZIN keys at the same time. Your position at the time these keys are pressed is used as the man overboard position. Caution: Saving a new "Man Overboard" waypoint will erase the previous "Man Overboard" waypoint.
Navigate Back to MOB Waypoint
Find your way back to the accident position with the Navigation Page or Map Page. When MOB is activated, the Navigation Page automatically shows the compass rose with its bearing arrow pointing toward the man overboard position, and the destination name says "Going To Man Overboard." The Map Page displays a Man Overboard waypoint, represented by a human figure, and the steering arrow points where to steer to reach that position.
The cursor is redirected toward the Man Overboard position on the Map Page. The victim is astern of the vessel. The GPS shows which direction to steer for the rescue.
The man overboard position is also stored in the waypoint list for future reference. It can be edited the same as any other waypoint. To cancel navigation to MOB, press MENU|MENU| to CANCEL NAVIGATION|ENT| to YES|ENT. The unit stops showing navigation information.
Navigate to Cursor Position on Map
The GO TO CURSOR command navigates to the current cursor position on the map. It's a quick and handy way to navigate to anything you can see on the map display. 1. Use the cursor (controlled by the arrow keys) with the zoom in and zoom out keys to maneuver around the map until you find a location you'd like to visit. 2. Center the cursor over the location to select it. See the example in the following figure. Many map items such as waypoints, Points of Interest, towns, etc. can be "selected," and appear "highlighted" with a pop-up box. Other features, such as a river or a street intersection will not appear "highlighted," but the cursor will take you to those locations just the same.

Create and Save a Route You have the option of creating and editing a route in the unit, or you can make a route on your computer with our MapCreate 6 software.

PC-created Routes

MapCreate is the easiest method for preparing a route, simply because your PC's larger screen, keyboard and mouse are easier to manipulate than the gimbal-mounted unit. To load a MapCreate route into the unit, follow the instructions in MapCreate's manual for creating and saving a route as part of a GPS Data File (file format *.usr). Copy the GPS Data File to an MMC and insert the MMC in the unit. (See Sec. 2 for instructions on installing MMCs. To load the GPS Data File into the Unit memory, see the entry on Transfer Custom Maps & GPS Data Files in Sec. 6, Basic GPS Operations.
Routes Created in the Unit
You can create a route by selecting saved waypoints from the waypoint list or you can set a series of route waypoints on the map with cursor arrows and the ENT key. In this example, we'll create a route from the map. 1. From the NAVIGATION PAGE (WITH DIGITAL DATA), press MENU|ENT or from the MAP PAGE, press MENU|MENU| to ROUTE PLANNING|ENT.
