Inverse is a method where weak returns are shown with dark pixels and strong returns with lighter pixels. This has the benefit of ensuring that weak signals will be clearly visible on the display.
Structure ID represents weak returns as light pixels and strong returns as dark pixels. This has the benefit of ensuring that strong returns will be clearly visible on the display.
WhiteLine highlights the strongest sonar returns in white, resulting in a distinctive outline. This has the benefit of clearly defining the bottom on the display.
Bottom Black displays all pixels below the bottom contour as black, regardless of signal strength. This has the benefit of providing a high contrast between the bottom and other sonar returns on the display. Any targets such as fish, structure and thermoclines will be shown using the Structure ID method.

Sonar Zoom View

Sonar Zoom View increases the displayed resolution to separate sonar returns that are very close together, such as those caused by fish suspended close to the bottom or within structure. In Zoom View, the display is split to show a narrow slice of the full range view on the right and the zoomed view on the left. The full range view on the right also contains the Zoom Preview Box that shows what part of the full range view is shown in zoom view on the left; the Zoom Preview Box tracks the bottom in the full range view. As the depth changes, the zoomed view updates automatically to display a magnified image of the bottom. The Zoom Preview Box shows where the zoomed view is in relation to the full range view. The Zoom Level, or magnification, is displayed in the lower left corner and can be changed to suit conditions (see Sonar X-PressTM Menu: Zoom Level). Upper and Lower Zoom Depth Range numbers indicate the depth of the water which is being viewed. Digital depth is displayed in the upper left hand corner. The digital readouts in the Sonar Zoom View cannot be customized; therefore, information such as water temperature and voltage are unavailable in the Sonar Zoom View.

A right or left arrow on a menu choice means that you can use the RIGHT or LEFT Cursor keys to make changes or to see more information.
NOTE: The Main Menu choices will vary depending on whether you are in Normal or Advanced User Mode.
User Mode (Normal or Advanced) - An Advanced Mode is provided for users who desire the highest level of control over the 300 SeriesTM Fishing System and Normal Mode for users who desire greater simplicity and fewer menu choices. Additional Advanced menu choices will be displayed throughout the menu system when you navigate to specific menus while in Advanced Mode. Any changes made while in Advanced Mode will remain in effect after you switch back to Normal Mode. See Setup Menu Tab: User Mode for specific instructions on changing to Advanced User Mode.

Sonar Tab Normal Mode

Sonar Tab Advanced Mode
Total Screen Update - when you change any menu settings that affect the Sonar View, the view will update immediately (i.e. you dont have to exit the menu to apply the change to the screen). For instance, by switching between "Inverse" and "Structure ID" from the X-PressTM menu it is possible to alternate quickly between the two viewing methods.

Start-Up Options Menu

Press the MENU key when the Title screen is displayed to access the Start-Up Options menu. Use the UP or DOWN 4-WAY Cursor keys to position the cursor, then the RIGHT Cursor key to select one of the following choices. If you wait too long, the system will default to whichever menu mode happens to be highlighted:
Normal Simulator System Status.
See the following paragraphs for more information about each of these choices.

Normal Operation

Use Normal operation for on the water operation with a transducer connected. In addition, your 300 SeriesTM Fishing System uses advanced transducer detection methods to determine if a transducer is connected. If a functioning transducer is connected, Normal operation will be selected automatically at power up and your 300 SeriesTM Fishing System can be used on the water. Exit Normal operation by powering your 300 SeriesTM Fishing System off.

Simulator

Use the Simulator to learn how to use your 300 SeriesTM Fishing System before taking your boat on the water. The Simulator is a very powerful tool that simulates on the water operation, providing a randomly-updated display. We recommend going through this manual while using the Simulator, since all of the menus function and affect the display the way they actually do when in Normal operation.

NOTE: To get the full benefit of the Simulator, it is important to select Simulator manually from the Start-Up Options menu as opposed to letting the 300 SeriesTM Fishing System enter Simulator automatically (as it will if a transducer is not connected and you do nothing during power up). Manually selecting Simulator from the Start-Up Options menu allows you to preconfigure your 300 SeriesTM Fishing System for on the water operation. Any menu changes you make will be saved for later use.
A message will appear on the display periodically to remind you that you are using the Simulator. Exit the Simulator by powering your 300 SeriesTM Fishing System off.

System Status

Use System Status to view system connections and to conduct a unit self-test. The following screens are displayed in turn when you press the VIEW button when using System Status: Self Test Accessory Test GPS Diagnostic View. Exit System Status by powering your Fishing System off.

Self Test

Self Test displays results from the internal diagnostic self test, including unit serial number, Printed Circuit Board (PCB) serial number, software revision, total hours of operation and the input voltage.

Accessory Test

Accessory Test lists the accessories connected to the system.
NOTE: The speed accessory will be detected only if the paddlewheel has moved since your 300 SeriesTM Fishing System was powered up.
System Status Accessory Test Screen

GPS Diagnostic View

GPS Diagnostic View shows a sky chart and numerical data from the GPS receiver. The sky chart shows the location of each visible GPS satellite with its satellite number and a signal strength bar. A dark grey bar indicates that the satellite is being used to determine your current position. A light gray bar indicates that the satellite is being monitored, but is not yet being used.
Sky Chart Satellite Being Used
Satellite Being Monitored
Current Latitude and Longitude
This view also reports the current position, local time and date, and other numeric information. The current GPS Fix Type is reported as No Fix, 2D Fix, 3D Fix, or Enhanced. An Enhanced fix has been augmented using information from WAAS, EGNOS, or MSAS. A 3D or Enhanced Fix is required for navigation. HDOP (the Horizontal Dilution of Precision) is a GPS system parameter which depends on the current satellite configuration. HDOP is used to calculate the Estimated Position Error.

Bottom Range

(Sonar Zoom view only when Bottom Lock is On)
Bottom Range allows you to control how much of the water column, measured up from the bottom, is shown in the Sonar Zoom View. Choose a small value to see lowlying bottom structure or details of the bottom return. Choose a larger value to see large structure in deeper water. It is possible to set the Bottom Range to be greater than the depth. In this case, you may see surface clutter in a wavy band that mirrors changes in the depth. To adjust the Bottom Range: 1. In the Sonar Zoom View, highlight Bottom Range on the Sonar X-PressTM menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Bottom Range setting. (10 - 60 feet or 3-20 meters [International Models only], Default = 15 feet)

Bottom Lock

(Sonar Zoom view only)
Bottom Lock changes the mode of the Zoomed view in the Sonar Zoom View. Bottom Lock continuously graphs the bottom at a constant point on the display regardless of changes in depth. This "flattens" out the bottom contour, but is effective at showing fish on or near the bottom. To turn on Bottom Lock: 1. In the Sonar Zoom View, highlight Bottom Lock on the Sonar X-PressTM Menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Bottom Lock setting to on. (Off, On, Default = Off)

Cancel Navigation

(only when Navigating)
Cancel Navigation discards the current route and exits Navigation Mode. This menu choice will only appear when you are currently navigating a route. This will not delete a previously-saved route. To Cancel Navigation: 1. Highlight Cancel Navigation on the Sonar X-PressTM menu. 2. Use the RIGHT 4-WAY Cursor Control key to initiate canceling navigation. 3. The Confirm dialog box will appear. To cancel navigation, press the RIGHT Cursor key once more. To avoid canceling navigation, press the LEFT Cursor key. 4. The Save Current Route dialog box will appear. Use the RIGHT 4-WAY Cursor key to save the route or the LEFT 4-WAY Cursor key to decline saving the route.

Remove Grid

(only if a Grid is Active)
Remove Grid removes the waypoint grid from the display. This menu choice will only appear when a grid has already been applied to a waypoint.
To Remove a Grid: 1. Highlight Remove Grid on the Navigation X-PressTM menu. 2. Use the RIGHT 4-WAY Cursor Control key to remove the grid.

(Combo view only)

Sonar Window sets the size of the Sonar Window in the Combo View. Sonar Window can only be accessed from the Combo View. To Set the Size of the Sonar Window in the Combo View: 1. Highlight Sonar Window on the Navigation X-PressTM menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to adjust the size of the sonar window. (Wide, Medium, Narrow, Default = Medium)
(Most recently-created waypoint)
Waypoint [Name] allows you to view the waypoints submenu for the most recently created waypoint.
NOTE: You must have pressed the MARK key at least once since you last powered up the fishfinder for this menu choice to appear.
To view the Waypoint [Name] Submenu: 1. Move the cursor to the desired position and press the MARK key once to save a waypoint. 2. Highlight Waypoint[Name] on the Navigation X-PressTM menu. 3. Use the RIGHT 4-Way Cursor Control key to view the Waypoints submenu.

Waypoint [Name] Submenu

The Waypoint Submenu contains the following menu choices: Edit allows you to edit the Name, Position (Latitude and Longitude) and select the Icon that will be used to represent the waypoint in the Chart and Combo Views. Delete allows you to delete a waypoint from the list of saved waypoints. Go To allows you to select a waypoint and start navigation toward that waypoint, or add that waypoint to the end of the current route. Target allows you to apply a target to a waypoint selected from the list of waypoints. Grid allows you to apply a trolling grid to a waypoint selected from the list of waypoints.
Press the MENU key twice to access the Main Menu System and then press the RIGHT Cursor key to select the Sonar tab.
NOTE: Menu choices will vary depending on system settings such as whether the unit is set for Advanced User mode or what transducer is currently selected.

200 kHz, Narrow Beam Shaded Fish Symbols
83 kHz, Wide Beam Hollow Fish Symbols
When Fish ID+TM is turned off, the 300 SeriesTM Fishing System shows only the raw sonar returns on the display. These returns will often result in "arches" forming on the display, indicating potential targets. Due to the transducer beam angle, the distance to a fish decreases as the fish moves into the beam, and then increases as it moves out again, creating a Fish Arch when this distance change is shown on the display. Boat speed, chart speed, and the position of the fish within the sonar beam greatly affect the shape of the arch.
Transducer Cone and Fish Arches
To turn Fish ID+TM on or off: 1. Highlight Fish ID+ on the Sonar main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to turn the Fish ID+TM setting On or Off. (Off, On, Default = Off) 50

Fish ID Sensitivity

Fish ID Sensitivity adjusts the threshold of the Fish ID+TM detection algorithms. Selecting a higher setting allows weaker returns to be displayed as fish. This is useful for identifying smaller fish species or baitfish. Selecting a lower setting displays fewer fish from weak sonar returns. This is helpful when seeking larger species of fish. Fish ID Sensitivity is used in conjunction with Fish ID+TM. Fish ID+TM must be On for Fish ID Sensitivity to affect the ability of the 300 SeriesTM Fishing System to identify sonar returns as fish. To change the Fish ID Sensitivity setting: 1. Highlight Fish ID Sensitivity on the Sonar main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Fish ID Sensitivity setting. (Low = 1, High = 10, Default = 5)
RTS Window sets the RTS Window to either Wide or Narrow, or turns it off in the Sonar View. The RTS Window always updates at the fastest rate possible and only displays returns that are within the transducer beam. (See Real Time Sonar (RTS) Window for more information.)

RTS Window (Wide)

RTS Window (Narrow)

RTS Window (Off)

To change the RTS Window setting: 1. Highlight RTS Window on the Sonar main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the RTS Window setting. (Wide, Narrow, Off, Default = Wide) 51

Units - Speed selects the units of measure for speed-related readouts, and will appear in the menu if a Temp/Speed Accessory is connected and the paddlewheel has moved at least once, or if the GPS Receiver is connected. To change the Units - Speed setting: 1. Highlight Units - Speed on the Setup menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Units - Speed setting. (kph [International Models only], mph, kts, Default = kph for International models and mph for Domestic models)

Pixels, Vertical: Vertical Pixels are a number of vertical picture elements in a single column on an LCD display. A greater number of vertical pixels provide finer resolution of targets detected by sonar. Essentially, a vertical distance (the depth), when divided by a larger number, breaks that distance into smaller samples, each representing a smaller area and thus providing more detail. In fishfinders, vertical pixels are more critical than horizontal pixels because the horizontal axis of the display represents time, or history. Sonar information on the horizontal axis can vary greatly, depending on boat speed and the Chart Speed setting. A greater number of horizontal pixels show more sonar history that the boat has passed through. On many models, Humminbird provides the most vertical pixels to provide a better display resolution. See Chart Speed and Pixels. Power Output: Power output is the amount of sound energy emitted into the water by the sonar transmitter. Power output is measured using either RMS (Root Mean Square) or P-T-P (Peak-to-Peak) measurement systems. Either method is acceptable, but it is important, when comparing power outputs, to make sure that the same measurement system is being used for both outputs, because P-T-P numbers are 8 times higher than RMS numbers. Greater power output allows the sonar signal to penetrate through weeds and thermoclines, reach deeper depths and operate more effectively in noisy environments, such as when the boat is running at high speed. Pulse Width (Pulse Length): Pulse Width is the length of time that a sonar sound burst is transmitted into the water. Shorter pulse widths provide better target separation, but cannot travel to great depths. Longer pulse widths provide better depth penetration, but result in poorer target separation. Humminbird varies pulse width based on depth to optimize both target separation and depth performance. See Target Separation. QuadraBeamTM: QuadraBeamTM is a Humminbird sonar configuration that uses four sonar beams for a more detailed bottom image. QuadraBeamTM uses the DualBeam PLUSTM configuration for downlooking, and also adds two additional beams to look to the left and right. The sonar beams pointing to the left and right provide the ability to spot fish and structure over a wide 90 area, and to identify on which side of the boat they are located. See DualBeam PLUSTM. Quick Disconnect Mount: The Quick Disconnect Mounting system is an exclusive Humminbird feature that permits the unit to be easily removed from the mounting base by pressing a release button, and re-installed by simply snapping it back into 95

How Sonar Works
Sonar technology is based on sound waves. The 300 SeriesTM Fishing System uses sonar to locate and define structure, bottom contour and composition, as well as depth directly below the transducer. Your 300 SeriesTM Fishing System sends a sound wave signal and determines distance by measuring the time between the transmission of the sound wave and when the sound wave is reflected off of an object; it then uses the reflected signal to interpret location, size, and composition of an object. Sonar is very fast. A sound wave can travel from the surface to a depth of 240 ft (70 m) and back again in less than 1/4 of a second. It is unlikely that your boat can "outrun" this sonar signal. SONAR is an acronym for SOund and NAvigation Ranging. Sonar utilizes precision sound pulses or "pings" which are emitted into the water in a teardrop-shaped beam. The sound pulses "echo" back from objects in the water such as the bottom, fish and other submerged objects. The returned echoes are displayed on the LCD screen. Each time a new echo is received, the old echoes are moved across the LCD, creating a scrolling effect.
The sound pulses are transmitted at various frequencies depending on the application. Very high frequencies (455 kHz) are used for greatest definition but the operating depth is limited. High frequencies (200 kHz) are commonly used on consumer sonar and provide a good balance between depth performance and resolution. Low frequencies (83 kHz) are typically used to achieve greater depth capability.
The power output is the amount of energy generated by the sonar transmitter. It is commonly measured using two methods: Root Mean Square (RMS) measures power output over the entire transmit cycle. Peak to Peak measures power output at the highest points. The benefits of increased power output are the ability to detect smaller targets at greater distances, ability to overcome noise, better high speed performance and enhanced depth capability.
When all the echoes are viewed side by side, an easy to interpret "graph" of the bottom, fish and structure appears.

DualBeam PLUSTM Sonar
Your 300 SeriesTM Fishing System uses a 200/83 kHz DualBeam PLUSTM sonar system with a wide (60) area of coverage. DualBeam PLUSTM sonar has a narrowly focused 20 center beam, surrounded by a second beam of 60, expanding your coverage to an area equal to your depth. In 20 feet of water, the wider beam covers an area 20 feet wide. The 20 center beam is focused on the bottom, to show you structure, weeds and cover. The 60 wide beam is hunting for fish in the wide coverage area. DualBeam PLUSTM sonar returns can be blended together, viewed separately or compared side-by-side. DualBeam PLUSTM is ideal for a wide range of conditions - from shallow to very deep water in both fresh and salt water. Depth capability is affected by such factors as boat speed, wave action, bottom hardness, water conditions and transducer installation.

Birds Eye View
Bird's Eye View - This view shows a 3-D, perspective view of the track and the charts land contour from a point above and behind the boat (the eye point). As the boat turns, the eye point moves to follow the boat. When you press the 4-WAY Cursor key in the Birds Eye View, the position of the eye point will shift. This allows you to move and turn the eye point so that you can look off to the sides, or even behind the boat. Pressing the RIGHT or LEFT arrow keys on the 4-WAY Cursor key turns the eye point right or left, while pressing the UP arrow key moves the eye point forward, and pressing the DOWN arrow key moves the eye point backward. Pressing the EXIT key moves the eye point back to its original position behind and above the boat.

Chart View

Chart View - This view shows cartography from the built-in Uni-MapTM for the area surrounding your current position. The current track (also known as the position history or breadcrumb trail) showing where the boat has been, along with saved tracks, waypoints, and the current route (when navigating), are overlaid on the chart. You can use the 4-WAY Cursor Control key to shift/pan the chart to another area. You can use the ZOOM (+/-) keys to zoom in and out. You can use the INFO key to get information on the chart objects near the cursor.

Speed of Boat

Chart Speed

Chart Speed determines the speed at which the sonar information moves across the display, and consequently the amount of detail shown. A faster speed shows more information in the Sonar Views and is preferred by most anglers; however, the sonar information moves across the display quickly. A slower speed keeps the information on the display longer, but the bottom and fish details become compressed and may be difficult to interpret. Regardless of the Chart Speed setting, the RTS Window will update at the maximum rate possible for the depth conditions. Adjust Chart Speed to your personal preference. To adjust the Chart Speed: 1. Highlight Chart Speed on the Sonar X-PressTM menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the Chart Speed setting. (1-9, Ultra, where 1 = Slow, 9 = Fast, Ultra = Fastest, Default = 5)

Bottom View

Bottom View selects the method used to represent bottom and structure on the display. Inverse represents weak returns as dark pixels and strong returns as lighter pixels. This has the benefit of ensuring that weak signals will be clearly visible on the display. Structure ID represents weak returns as light pixels and strong returns as dark pixels. This has the benefit of ensuring that strong returns will be clearly visible on the display. WhiteLine highlights the strongest sonar returns in white resulting in a distinctive outline. This has the benefit of clearly defining the bottom on the display. Bottom Black displays all pixels below the bottom contour as black, regardless of signal strength. This has the benefit of providing a high contrast between the bottom and other sonar returns on the display. Any targets such as fish, structure and thermoclines will be shown using the Structure ID method. See Bottom Presentation for more information. To adjust the Bottom View: 1. Highlight Bottom View on the Sonar X-PressTM Menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Bottom View setting. (Inverse, Structure ID, WhiteLine, Bottom Black, Default = Inverse)
To adjust the Lower Range: 1. Highlight Lower Range on the Sonar X-PressTM menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the Lower Range setting. (AUTO, 10 to 1000 feet, 3 to 330 meters [International Models only], Default = AUTO)

300 SeriesTM Doesnt Power Up
If your 300 SeriesTM Fishing System doesnt power up, use the Installation Guide that also comes with it for specific confirmation details, making sure that: The power cable is properly connected to the 300 SeriesTM Fishing System control head. The power cable is wired correctly, with red to positive battery terminal and black to negative terminal or ground. The fuse is operational. The battery voltage of the power connector is at least 10 Volts. Correct any known problems, including removing corrosion from the battery terminals or wiring, or actually replacing the battery if necessary.
When the boat moves at higher speeds, the bottom disappears or suddenly weakens, or the display contains gaps.
300 SeriesTM Defaults to Simulator with a Transducer Attached
A connected and functioning transducer will cause the newly-started 300 SeriesTM Fishing System to go into Normal operating mode automatically. If, when you power up the 300 SeriesTM Fishing System, it goes into Simulator mode automatically, even though a transducer is already connected, this means that the control head is not detecting the transducer. Perform the following troubleshooting tasks: Using the Installation Guide that also comes with your 300 SeriesTM Fishing System, check to make sure that the transducer cable is securely connected to the 300 SeriesTM Fishing System. Reconnect if necessary, and power up the 300 SeriesTM Fishing System again to see if this fixes the problem. Replace the non-functioning transducer with a known good transducer if available and power up the control head again. Check the transducer cable. Replace the transducer if the cable is damaged or corroded. 87

Finding the Cause of Noise
Electrical noise usually affects the display with many black dots at high speeds, and high sensitivity readings. One or more of the following sources can cause noise or interference: Possible Source of Noise Other electronic devices Isolation Turn off any nearby electronic devices to see if the problem goes away, then turn them on one at a time to see if the noise re-appears. To determine whether the boats engine is the source of the noise, increase the RPMs while the boat is in neutral and stationary to see if the noise increases proportionately; if noise appears when you rev the engine, the problem could be the spark plugs, alternator, or tachometer wiring. Replace the spark plugs with resistor plugs, install an alternator filter, or route the control head power and transducer cables away from the engine wiring. Turbulence created by the propeller can cause noise; make sure the transducer is mounted at least 15 (38 cm) from the propeller, and that the water flows smoothly over the face of the transducer at all times.

back into place. All cable connections are made when installing, so that no separate wiring connections are required. Additionally, the mount offers 90 tilt and 360 swivel capability to adjust the viewing angle of the unit as you move about the boat. Real Time Sonar: Real Time Sonar is a Humminbird technology that delivers ultrafast sonar transmitter/receiver operation and results in a more detailed instantaneous view of what is under the boat. The Real Time Sonar window is a vertical band at the right side of the display that shows the instantaneous sonar return from the transducer at a particular instant. The RTS Window menu option permits the user to adjust the window to show the full sonar signal return, or just a narrower band that indicates intensity using grayscale. Real Time Sonar relies on very fast Sonar Update Rate (Ping Speed). See Sonar Update Rate. Receiver: See Transmitter. Second Return: The Second Return is a term that describes the appearance of a second sonar return below the primary sonar return (bottom contour) at exactly twice the true depth. The second return is caused by the same sonar energy bouncing off the bottom once, rebounding to the water surface and then traveling back down to the bottom to be reflected again. Second returns are more common in shallow water and over hard bottoms; it is actually possible to see a third sonar return under some circumstances. The second return provides useful information to help determine bottom hardness, as areas with harder bottoms will generally create a second return. The second return can be used as a guide to set Sensitivity when in shallower water. Sensitivity: Sensitivity is a user feature that adjusts the sensitivity of the sonar system to show more or less detail in the water. Higher sensitivities are often preferred, however, when the water contains debris (silt, storm debris, etc.) and it can be difficult to pick out targets. Conversely, if sensitivity is set too low, relevant targets may be missed. SONAR: SONAR is the acronym for SOund and NAvigation Ranging. Sonar technology uses precision sound bursts transmitted underwater to determine the distance and other attributes of objects in the water. Distance can be determined because the speed of sound in water is constant, and the time for the signal to return is measured. Sound also travels very quickly underwater, making sonar a responsive, cost-effective tool. Sonar is the basic technology behind all recreational and commercial fishfinding and depthfinding devices. 96

Page 106

Transmitter: The transmitter and receiver are matched parts of the sonar system that send (transmit) and listen to (receive) the sonar signals, and work in conjunction with the transducer. Humminbird transmitters have an extremely fast cycling design that can send signals up to 60 times per second, as well as produce the varying levels of power output needed for different depths and conditions. Additionally, the transmitter has the capability to create very precise sonar pulses needed for a high degree of target separation. Humminbird receivers are extremely sensitive, but within a narrow "bandwidth" to discriminate against noise from external sources. Additionally, the receiver offers a wide "dynamic range" which provides the ability to receive very strong signals alternating with very weak signals, without the strong signal overwhelming the weak signal. See Transducer and Noise. TripLog: TripLog is a Humminbird feature that provides an on-screen counter for Elapsed Time, Average Speed and Total Distance traveled, and requires a speed input to activate the feature. TripLog appears on the Big Digits View, and can be reset to zero through the TripLog menu. TrueArch: TrueArch is a Humminbird feature that provides true fish arches, not artificial arches or symbols. Humminbird units are capable of producing fish arches due to the wide 60 sonar beam of DualBeam PLUSTM, an extremely sensitive sonar receiver. See Fish Arch. Viewing Angle: Viewing Angle is an attribute of an LCD that characterizes visibility of the display when viewing from off the central access, such as when standing to the side of the fishfinder. Wider viewing angles are better because the information remains visible even when viewing from the side. WhiteLine: WhiteLine is a Humminbird feature that highlights the strongest sonar return on the display using a very light gray band. This is preferred by some anglers who have grown accustomed to the feature on paper graph chart recorders. WideSide: WideSide is a Humminbird sonar configuration used in an optional transducer. WideSide uses three sonar beams pointing to the left, right and down. Beams pointing to the left and right are effective for spotting fish and structure near the surface or on the bank. The downlooking beam provides depth information directly below the boat. X-PressTM Menu: X-PressTM Menus are a Humminbird feature that make the most commonly-used menu selections available with one press of the MENU key. Items that 99
appear on the X-PressTM Menu are related to the current view, and present the most logical choices for that view. Sonar View X-PressTM menus will differ from Chart View X-PressTM menus, etc. X-PressTM menus are one of the principal reasons that Humminbird products are easier to use. Zoom: Zoom is a feature that focuses in on a smaller area of the bottom to provide enhanced resolution. With enhanced resolution, the angler can more easily see fish hanging in structure or multiple fish hanging close together. Split screen zoom divides the display into the full range view on the right, and the zoomed view on the left. Humminbird offers One-Touch Zoom which allows the zoom feature to be easily accessed from the regular sonar view with just one key press, eliminating the need to use menus to access the feature. Zoom, Bottom Lock: Bottom Lock Zoom is a feature that focuses on a smaller area just above the bottom to provide enhanced resolution. Unlike regular zoom, it continuously graphs the bottom at a constant point on the display regardless of changes in depth. This "flattens" out the bottom contour, but is effective at showing fish on or near the bottom, and is preferred by many saltwater anglers.

GPS & Navigation Terms:
Acquisition Time: The length of time that a GPS receiver typically takes to determine a position from at least three satellites. Humminbird GPS receivers provide very fast acquisition times (under one minute), permitting users to get out on the water faster. Alarm, Arrival: The audible alert that sounds when the boat is equal to or less than the alarm setting (25 feet3000 feet) from the location of the destination waypoint. Alarm, Drift: Drift Alarm is an audible alert that sounds when the boat is equal to or over the alarm setting (25 feet3000 feet) from the location where the alarm was turned on. Alarm, Off-Course: Off-Course Alarm is an audible alert that sounds when the boats distance from the intended Track, (Cross Track Error), is equal to or over the alarm setting (25 feet 3000 feet). See Track and Cross Track Error. Altitude: Altitude measures height above sea level. Altitude is a measurement that can be provided by GPS.

Page 108

Bearing (BRG): Bearing is the direction to a destination waypoint measured in degrees from North (i.e. 321, where 000 is North, 090 East, 180 is South, 270 is West). Chartplotter: Chartplotter describes a navigation device that shows Present Position on a Map, along with Tracks, Waypoints, and Routes. All Chartplotters are also considered Trackplotters. All Humminbird GPS Combo units are Chartplotters. See Trackplotter. Cold Start: Cold Start refers to the procedure that a GPS receiver must perform when it does not have historical information regarding its current location. This procedure typically lasts for several minutes, and may be experienced upon first power up of the receiver, or if the receiver has been moved a great distance. Course Over Ground (COG): Course Over Ground is the current direction the boat is traveling measured in degrees from North (i.e. 321, where 000 is North, 090 East, 180 is South, 270 is West). When the Course Over Ground is equal to Bearing, the boat is said to be On Course and will arrive at the destination in the most efficient manner. COG is often confused with Heading. See Heading. Cross Track Error (XTE): Cross Track Error is the straight-line distance of the boat from the intended Track. XTE measures how far the boat is off course, and also triggers the Off Course Alarm. See Track. Differential GPS (DGPS): Differential GPS is a system to improve the position accuracy of the Department of Defense GPS through the use of secondary correction signals broadcast from ground stations around the coastal United States and on some inland waterways. These correction signals are provided by the USCG and received by an auxiliary Differential Beacon Receiver (DBR) that connects to the GPS receiver. The advent of WAAS has largely negated the need for the added expense of a DBR in the United States. Distance To Go: Distance To Go is the straight-line distance between Present Position and the Destination Waypoint. DTG and SOG (Speed Over Ground) are used to calculate Time To Go. See Time to Go and Speed Over Ground. Estimated Position Error (EPE): Estimated Position Error is a calculation that indicates the potential position inaccuracy the user may experience due to a variety of GPS factors which include satellite position in the sky, signal strength and others factors.

Speed Over Ground (SOG): Speed Over Ground is the measurement of the boats progress across a given distance, and is the speed measurement provided by GPS. An alternate, Speed Through Water, is provided by a speed paddlewheel, and is the measurement of the flow past the boat, which may vary depending on current speed and direction. Speed Over Ground is optimal for navigation because accurate destination times can be derived from this measurement. Humminbird products allow for input and display of both speed measurements. Time To Go (TTG): Time To Go is the estimated time required to reach the destination waypoint. TTG is calculated using the SOG and DTG. See SOG and DTG. Track: A Track is a series of saved points that define the past path of the boat. These Track Points are saved at regular time intervals. Tracks are a useful and quick method to see where youve been, and an easy guide to follow to get you back to the starting point. Generally, all GPS units have a limited number of Track Points that can be saved before the unit runs out of memory and begins erasing the first track points saved. Because of this, the user can adjust the Track Point Interval menu to increase the amount of time between when points are saved, and thus extend the distance covered by a track. Tracks can also be permanently saved to memory, and re-displayed at the users option. Track Line (TRK): The Track Line is the desired line of travel between two waypoints, and represents the most efficient path between the two points because it is a straight line. The TRK is measured in degrees (i.e. 321, where 000 is North, 090 East, 180 is South, 270 is West). See Cross Track Error and Course Over Ground. Trackplotter: Trackplotter describes a navigation device that shows Present Position, along with Track, Waypoint, and Routes, but NO MAP in the background. See Chartplotter. Trolling Grid: Trolling Grid is a Humminbird feature that displays a precise reference grid around a waypoint. This grid is used as a guide pattern for trolling around a specific area to assure a more efficient and complete coverage of that area. Trolling Grid resolution be changed by zooming in or out on the chart. The Trolling Grid can also be rotated on the display to orient it for optimal boat course for wave and wind conditions. UTC: UTC is an acronym for Universal Time Constant. UTC is the standard time used in navigation, and is the local time in Greenwich England. (UTC is equivalent to Greenwich Mean Time (GMT)). To display the correct Local Time in a Humminbird GPS unit, the user must use the Local Time Zone menu and select the time zone (i.e. EST, CST). 104

Page 112

WAAS: WAAS is an acronym for Wide Area Augmentation System. WAAS is complementary technology to GPS that provides enhanced accuracy through correction signals broadcast from Federal Aviation Administration WAAS satellites stationed over the USA. These secondary signals are automatically received by the standard Humminbird GPS Receiver. With WAAS signal, GPS accuracy is improved to within 3 meters 95% of the time. Outside the United States, regional governmental coalitions have created similar systems such as EGNOS (Europe) and MSAS (Japan). Waypoint: A Waypoint is the saved location (latitude, longitude) of a point of interest that is stored in a GPS receivers memory. This can include a marker buoy, dock, fishing hole or anywhere else the user may want to return to. Humminbird products offer the ability to name and assign a symbol to the saved location. Depth, Date and Time of Day when the waypoint was created is also saved. Waypoint Target: Waypoint Target is a Humminbird feature that displays a precise bulls eye around a selected waypoint. This bulls eye is used to easily monitor boat position relative to a waypoint, and is useful for fishing over submerged structure. With Waypoint Targets, a quick look at the screen lets you know how far off the waypoint the boat has drifted.
