under and adjacent to your boat, including the following items:
High Sonar Intensity Return Bait Ball Thermoclines - layers of water with different temperatures that appear at different depths and different times of the year. A thermocline typically appears as a continuous band of many colors moving across the display at the same depth. 83 kHz Blue Fish Symbol Fish - the FishFinder displays fish as arches and/or fish icons, and can be set to alarm when a fish of a certain size is detected. When a target is detected, a Fish ID+TM symbol appears on the display with the depth displayed above it. The size of the symbol indicates the intensity of the sonar return. The unit will clearly show schools of Bait Fish as "clouds" of different shapes and sizes, depending on the number of fish and boat speed. 200 kHz Orange Fish Symbol Structure - where fish may be hiding.

Navigation views:

Birds Eye View Chart View Combo View.
NOTE: When you change any menu settings that affect the sonar, the view will update immediately (i.e. you dont have to exit the menu to apply the change to the screen).
Sonar View is the default view. When the VIEW key is pressed, the display cycles through the available views. When the EXIT key is pressed, the display cycles through the available views in reverse order. Any view can be hidden or displayed as part of the view rotation using the Views Menu tab.

Sonar View

Sonar View presents a historical log of sonar returns. Depth is always displayed. Readouts for temperature and speed are automatically displayed if the appropriate accessory is connected. The most recent sonar returns are charted on the right side of the window; as new information is received, the older information is moved across the display to the left. A Digital Depth Readout is displayed in the upper left corner. A scale with Upper and Lower Depth Range readouts appears along the right edge of the Sonar View. The scale indicates the distance from the surface of the water to a depth range sufficient to show the bottom. Depth Range is automatically selected to keep the bottom visible on the display, although you can adjust it manually as well (see Sonar X-Press Menu). Five additional Digital Readouts display information from optionalpurchase accessories. These information boxes can be customized to show only the information desired (see Setup Menu Tab, Select Readouts).

Bottom Contour Profile with RTS Window. Temp/Speed Accessory is optional.
Hard Bottom Soft Bottom Rocky Bottom
The sonar returns from the bottom, structure and fish can be represented as either WhiteLine or Structure ID. See Sonar Menu Tab: Bottom View for details on how to set the bottom view. 10
Structure ID represents weak returns in blue and strong returns in red.
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.

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-Press 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.

200/83 kHz Split Sonar View
Split Sonar View displays sonar returns from the 83 kHz wide beam on the left side of the screen and displays sonar returns from the 200 kHz narrow beam on the right side of the screen. Depth is always displayed in the upper left hand corner. You can use the Split Sonar View to make side by side comparisons between the sonar returns from the 83 kHz wide beam and the 200 kHz narrow beam. The digital readouts in the Split Sonar View cannot be customized; therefore, information such as water temperature and voltage are unavailable in the Split Sonar View.

Combo View

Combo View - This view is displayed as a split screen, with Chart View on the left and Sonar View on the right side of the screen. The width of the sonar window can be changed.

View Orientation

Both Chart and Combo views allow you to choose the orientation of the view. When North-Up orientation is selected, True North is shown at the top of the display. In other words, objects located to the north of the boat are drawn above the boat. When Course-Up orientation is selected, the direction of motion of the boat is shown at the top of the display. In other words, objects ahead of the boat are drawn above the boat. In both orientations, the view pans automatically, so that the boat is always centered on the display. When the boat is stationary, it is drawn as a circle. When the boat is in motion, it takes on a boat shape, pointed in the direction of motion (always Up in the Course-Up orientation).

Viewing Cartography

In the Chart or Combo Views there are several cartography-related functions that you can access using various keys. Panning: Use the 4-WAY Cursor keys to move the chart around on the display in the direction of the key being pressed. When you do this, a bull's eye cursor is drawn at the center of the screen and is linked to the boat by a gray line, even if the boat is off the screen. At the same time, the temperature and speed boxes in the lower left corner are replaced with the distance and bearing from the boat to the cursor position and the latitude/longitude coordinates of the cursor.
Chart View with Cursor Present
Zooming: Use the Plus (+) key to Zoom In and the Minus (-) key to Zoom Out showing the cartography at different scales. The scale is indicated on the left side of the display. If you zoom in beyond the available chart data, the display will go into Overzoom mode whereby the last available chart data is amplified to reflect the scale selected. If you zoom in so far that no cartography is available, a lat/long grid will be drawn instead. Chart Info: Use the INFO key to get detailed information about the chart. If the cursor is active, you will see information about the chart objects located near the cursor.
Introduction to Navigation
Use the 300 Series Fishing System to establish waypoints at areas of interest and to navigate to those waypoints via a savable route (representing the shortest intended distance between waypoints). You can also view and save tracks, which represent the actual path of the boat.

Add a Waypoint Target or Trolling Grid

Waypoint Target

Chart View with Target
Add or Remove a Waypoint Target: From the Waypoints submenu, select Target and press the RIGHT Cursor key to display a list of waypoints. Select the waypoint you want to target. A target consisting of concentric circles centered on the selected waypoint will appear on all of the navigation views; the target shows various distance ranges from the targeted waypoint. To remove the target, choose Remove Target from the Navigation X-Press menu.

Waypoint Trolling Grid

Chart View with Grid
Add or Remove a Trolling Grid: From the Waypoints submenu, select Grid and press the RIGHT Cursor key to display a list of waypoints. Select the waypoint to which you want to add the grid. The trolling grid will appear on all of the navigation views, and can be used as a guide when trolling around a waypoint. The grid can be rotated to any desired heading using Grid Rotation from the Navigation Main menu. To remove the trolling grid, choose Remove Grid from the Navigation X-Press menu.
NOTE: Only one waypoint can have either a target or a grid at one time. If you apply a target or a grid to a new waypoint, the original waypoint will lose its target or grid. NOTE: The spacing of the rings on the waypoint target and the spacing of the grid lines on the trolling grid is the same as the length of the scale bar on the left edge of the display. Zooming in or out will decrease or increase the spacing, respectively.

The Menu System
The menu system is divided into easy-to-use menu modules. The main components of the menu system are: Start-Up Options Menu - Press the MENU key during the power up sequence to view the Start-Up Options menu. X-PressTM Menu - The X-PressTM menu allows you to access the settings that are changed frequently without having to navigate through the whole menu system. Press the MENU key once to display the X-PressTM Menu. When you select a menu item from the X-PressTM menu, the menu will collapse, leaving only the menu choice on the screen. Use the Up or Down Cursor keys to reactivate the X-PressTM menu.

X-PressTM Menu

NOTE: The X-PressTM Menu choices will vary depending on which view is active when you press the MENU key, as well as whether you are in Normal or Advanced User Mode. Either the Sonar or Navigation X-PressTM Menu will appear, depending on the view you are in.
Main Menu Tabs - Less frequently-adjusted menus are grouped into the Main Menu System. The Main Menu system is organized under the following tab headings to help you find a specific menu item quickly: Alarms, Sonar, Navigation, Chart, Setup, and Views.
Main Menu System Normal User Mode
Press the MENU key twice for the Main Menu, then use the 4WAY Cursor LEFT or RIGHT key to select a tab, and use the DOWN or UP key to select a specific menu item under that tab, then use the LEFT or RIGHT keys again to change a menu setting. Press the EXIT key to move quickly to the top of the tab. A down arrow at the bottom of a menu means that you can scroll to additional menu choices using the DOWN Cursor key. 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.

Lower Range

Lower Range sets the deepest depth range that will be displayed. Automatic is the default setting. When in automatic mode, the lower range will be adjusted by the unit to follow the bottom. Selecting a specific setting locks the depth range into Manual mode. Use both Upper and Lower Range together to view a specific depth range manually when looking for fish or bottom structure. M will be displayed in the lower right corner of the screen when you start manually adjusting the Lower Range to indicate that you are in Manual mode.
For example, if you are fishing in 60 feet of water but are only interested in the first 30 feet (surface to a depth of 30 feet) you should set the Lower Depth Range limit to 30. The display will show the 0 to 30 foot range, allowing you to see a more detailed view than you would see if the display went all the way to the bottom.
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)

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-Press 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 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 low-lying 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-Press 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)

Save Current Route

Save Current Route allows you to save the current route being displayed. This menu choice will only appear when you are currently navigating a route. To Save Current Route: 1. Highlight Save Current Route on the Navigation X-PressTM menu. 2. Use the RIGHT 4-WAY Cursor Control key to initiate saving the current route. 3. The Confirm dialog box will appear. To save the current route, press the RIGHT Cursor key once more. To cancel saving the current route, press the LEFT Cursor key.

Skip Next Waypoint

Skip Next Waypoint removes the next waypoint from the current route. This menu choice will only appear when you are currently navigating a route. To Skip Next Waypoint: 1. Highlight Skip Next Waypoint on the Navigation X-PressTM menu. 2. Use the RIGHT 4-WAY Cursor Control key to initiate skipping the next waypoint. 3. The Confirm dialog box will appear. To skip the next waypoint, press the RIGHT Cursor key once more. To cancel skipping the next waypoint, press the LEFT Cursor key.
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 Navigation 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.

Chart Detail Level
Chart Detail Level allows you to select how much chart detail you want displayed on the Navigation Views. Basic shows land areas, ports, obstructions and restricted areas. Navigation shows navaids, landmarks, ferryways and navigation routes in addition to the Basic information. Underwater shows depth contours, fishing areas, underwater wrecks, tides and currents in addition to the Basic and Navigation information. All shows roads, buildings, railways, and other notations in addition to the Basic, Navigation and Underwater information. To change the Chart Detail Level setting: 1. Highlight Chart Detail Level on the Chart main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Chart Detail Level setting. (Basic, Navigation, Underwater, All, Default = All)

Chart Speed: Chart Speed is a user-controllable feature that sets the speed at which sonar information moves across the display. A faster setting displays sonar information from more pings and shows more detail, but the information moves quickly across the display: a slower setting permits viewing of more sonar history, but does not display as much detail. The best setting is often the user's personal choice. Cone Angle: The cone angle is the angular measurement of the sonar beam at a specific dB down point (i.e. -10 dB). See dB Down Point. Customizable Digital Readouts: Customizable Digital Readouts is a Humminbird feature that permits the user to select the specific digital information that appears in the main Sonar view (i.e. Speed, Temperature, Barometric Pressure, TripLog, etc.) Dead Zone: The dead zone is the area of the sonar beam that receives the sonar signal after the main bottom return. Fish and other objects close to the bottom that fall within the dead zone will probably not be visible in the sonar beam. Precision sonar beams, such as the Humminbird 20 beam, have a smaller dead zone than wider sonar beams. Decibel: A Decibel is the measurement for sound pressure level, or "intensity" of the sonar return. See dB Down Point. dB Down Point: The dB Down Point is the standard decibel level at which the sonar cone angle is measured, and is written as "@ -10 dB" or "@ -3 dB". Measurements at smaller down points (bigger negative numbers) indicate that the less intensive sonar signals are being used for the measurement. Display, FSTN: FSTN is an acronym for Film Super-Twist Nematic. FSTN is a monochrome display technology characterized by black, high-contrast pixels. All monochrome fixed mount Humminbird products use FSTN technology. DualBeam PLUS: DualBeam PLUS is a Humminbird sonar configuration that uses two sonar beams simultaneously, and combines the information from both beams into one view by overlapping the data on-screen, or shows each beam individually side by side, or permits each beam to be viewed individually full screen. Feature Memory: Feature Memory is a Humminbird feature that retains the user's menu settings in permanent memory. Settings are retained even when the unit is powered off indefinitely.
Fish Arch: A Fish Arch is the apparent "arch" that appears on the display when any object moves through the sonar cone. The arch results from a gradual decrease in distance to an object as it moves into the sonar cone. The distance to an object changes due to the conical shape of the sonar beam, which causes the distance to be greater at the edges of the beam than at the center of the beam. When this distance change is graphed on the display, an arch appears. Fish ID+: Fish ID+ is a Humminbird feature that uses advanced sonar processing algorithms to determine if a detected object is likely to be a fish. When the sonar signal from an object meets strict parameters, the unit draws a Fish Symbol (or icon) and the digital depth of the target. On DualBeam and DualBeam PLUS units, fish detected in the narrow center beam are shown as shaded symbols, and fish detected in the wider beam are shown as hollow symbols. Fish Symbol: A Fish Symbol is the graphic that is displayed on the screen when Fish ID+ determines that a sonar return is likely to be a fish. See Fish ID+. Freeze Frame: Freeze Frame is a Humminbird feature that pauses the sonar scrolling so that the image on screen can be studied with greater detail. See Instant Image Update. Frequency: Frequency is a measure of the number of sound wave cycles per second of a sound impulse transmitted underwater. A typical frequency for fishfinders is 200 kHz, which offers a good balance of performance under many conditions. Lower frequencies, such as 50 kHz, are capable of penetrating to greater depths, but with less resolution. Higher frequencies, such as 455 kHz, offer greater resolution, but are limited in depth performance. Humminbird uses a variety of frequencies that are optimized for specific applications. Grayscale: Grayscale is the use of varying shades of gray to represent the strength of the sonar signal on the display , and is a very intuitive method of presenting information. Traditionally, the strongest sonar signals are represented in black, and progressively weaker signals are represented in progressively lighter shades of gray. Grayscale, Inverse: Inverse Grayscale is a Humminbird feature that reverses the correlation of sonar signal strength and the shade of gray typically used to represent it. The strongest sonar signals are represented by "white", and progressively weaker signals are represented in progressively darker shades of gray. While somewhat counterintuitive, this method makes the sonar images crisper, and has the benefit of enhancing 94

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.

How Sonar Works

Sonar technology is based on sound waves. The 300 Series Fishing System uses sonar to locate and define structure, bottom contour and composition, as well as depth directly below the transducer. Your 300 Series 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 teardropshaped 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.
When all the echoes are viewed side by side, an easy to interpret "graph" of the bottom, fish and structure appears.
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.

DualBeam PLUS Sonar

Whats On the Display

The 300 Series Fishing System can display a variety of useful information about the area
Depth - water depth; can be set to alarm when the water becomes too shallow. Cursor - available in Freeze Frame and can be positioned in the Sonar View to provide depth of a sonar return and bottom depth below the cursor. Temperature - water surface temperature. Timer - Elapsed time with Temp/Speed Accessory or GPS Receiver. Distance - Distance traveled with Temp/Speed Accessory or GPS Receiver. Average Speed - Average speed reading with Temp/Speed Accessory or GPS Receiver. Speed - if a Temp/Speed accessory or GPS Receiver is attached, the FishFinder can display the speed of the boat, and can keep a Triplog of nautical or statute miles traveled. Second Sonar Return - when the sonar signal bounces between the bottom and the surface of the water and back again. Use the appearance of the second return to determine bottom hardness. Hard bottoms will show a strong second return, while soft bottoms will show a very weak one or none at all. Cursor Dialog Box - indicates cursor depth on the display and the depth of the bottom directly below the cursor. The Latitude and Longitude of the cursor position, the distance to travel to the cursor position and the bearing to the cursor position is shown with a GPSreceiver. A waypoint can be marked at the cursor position for later retrieval and use with a GPS receiver.
NOTE: Entries in this view that list (with Temp/Speed or GPS Receiver) are available if either only the information from the GPS receiver will be displayed on the view.
under and adjacent to your boat, including the following items:
High Sonar Intensity Return Bait Ball Thermoclines - layers of water with different temperatures that appear at different depths and different times of the year. A thermocline typically appears as a continuous band of many colors moving across the display at the same depth. 83 kHz Blue Fish Symbol Fish - the FishFinder displays fish as arches and/or fish icons, and can be set to alarm when a fish of a certain size is detected. When a target is detected, a Fish ID+TM symbol appears on the display with the depth displayed above it. The size of the symbol indicates the intensity of the sonar return. The unit will clearly show schools of Bait Fish as "clouds" of different shapes and sizes, depending on the number of fish and boat speed. 200 kHz Orange Fish Symbol Structure - where fish may be hiding.

Save, Edit, or Delete a Waypoint
Save your current position as a waypoint: On any view, press the MARK key to save the current position of the boat as a waypoint.

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:

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 orange 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.

Sonar X-PressTM Menu

(Sonar views only)
The Sonar X-PressTM menu provides access to the settings most frequently-used. Press the MENU key once while in any of the Sonar Views to access the Sonar X-PressTM menu.
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.

Sensitivity

Sensitivity controls how much detail is shown on the display and will adjust the sensitivity of all sonar frequencies. Increasing the sensitivity shows more sonar returns from small baitfish and suspended debris in the water; however, the display may become too cluttered. When operating in very clear water or greater depths, increased sensitivity shows weaker returns that may be of interest. Decreasing the sensitivity eliminates the clutter from the display that is sometimes present in murky or muddy water. If Sensitivity is adjusted too low, the display may not show many sonar returns that could be fish.
NOTE: The Sensitivity setting is a global setting and will adjust the sensitivity of all sonar frequencies, as compared to specific sensitivity adjustments (such as 83 kHz Sensitivity) that allow you to adjust the level of sensitivity for one specific beam at a time.

Sensitivity at Low

Sensitivity at Medium

Sensitivity at High

Beam Select sets which sonar returns from the transducer will be displayed on the screen. When set to 200/83 kHz, the returns from both beams are blended by starting with the 83 kHz wide beam return, dimming it, and then overlaying it with the 200 kHz narrow beam return. The darker 200 kHz narrow beam sonar returns will stand out from the paler 83 kHz wide beam sonar returns. The Split Sonar View continues to display the sonar returns from each beam in their respective windows. The blended information is shown in the Sonar View, Sonar Zoom View, and the Big Digits View. The RTS Window in the Sonar View and the Circular Flasher View will only show the returns from the 200 kHz narrow beam. When set to 200 kHz, only the returns from the 200 kHz narrow beam will be displayed in the Sonar View, the Sonar Zoom View, the Big Digits View and the Circular Flasher View. The Split Sonar View will continue to display returns from both beams in their respective windows. The RTS Window in the Sonar View will display the returns from the 200 kHz narrow beam. When set to 83 kHz, the returns from the 83 kHz wide beam will be displayed in the Sonar View, the Sonar Zoom View, the Big Digits View and the Circular Flasher View. The Split Sonar View will continue to display returns from both beams in their respective windows. The RTS Window will display the returns from the 83 kHz wide beam. To use Beam Select: 1. Highlight Beam Select on the Sonar main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to select either the 83 kHz beam, the 200 kHz beam, or the 200/83 kHz beam. (200/83 kHz, 200 kHz, 83 kHz, Default = 200 kHz)

Fish ID+TM

Fish ID+TM uses advanced signal processing to interpret sonar returns, and will display a Fish Symbol when very selective requirements are met. When a fish is detected, a fish icon and its depth are displayed above the return that has been classified as being a fish. Three different fish size icons represent the intensity of the sonar return, and provide an indicator of relative fish size. DualBeam PLUSTM sonar models represent targets detected in the 200 kHz narrow beam as Orange Fish Symbols, and represent targets detected in the 83 kHz wide beam as Blue Fish Symbols.
200 kHz, Narrow Beam Orange Fish Symbols
83 kHz, Wide Beam Blue Fish Symbols

When Fish ID+TM is turned off, the 300 Series 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+ 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 Series 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

Bottom View

Bottom View selects the method used to represent bottom and structure on the display. Structure ID represents weak returns in blue and strong returns in red. 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. See Bottom Presentation for more information. To adjust the Bottom View: 1. Highlight Bottom View on the Sonar main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Bottom View setting. (Structure ID, WhiteLine, Default = Structure ID)

To change the Fish ID Alarm setting: 1. Highlight Fish ID Alarm on the Alarms main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Fish ID Alarm setting. (Off, All, Large/Medium, Large, Default = Off)
Off Large Large/Medium All

Low Battery Alarm

Low Battery Alarm sounds when the input battery voltage is equal to or less than the menu setting. The battery alarm will only sound for the battery that is connected to the 300 Series Fishing System. The Low Battery Alarm should be set to warn you when the battery voltage drops below the safety margin that you have determined. For instance, if you are running a trolling motor (battery operated), you would want to set the Low Battery Alarm to sound before the battery voltage drops too low for it to be used to start your main, gasoline-powered engine. To change the Low Battery Alarm setting: 1. Highlight Low Battery Alarm on the Alarms main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Low Battery Alarm setting. (Off, 8.5V - 13.5V, Default = Off)

Temp Alarm

Temp Alarm sounds when the water temperature detected by the 300 Series reaches the Temp Alarm setting, which is either set in degrees Fahrenheit or Celsius [International Models only]. For example, if the Temp Alarm is set to 58 degrees Fahrenheit, and the water temperature falls from 60 degrees to 58 degrees, the Temp Alarm will sound. Similarly, if the water temperature rises from 56 degrees to 58 degrees, the Temp Alarm will also sound. To change the Temp Alarm setting: 1. Highlight Temp Alarm on the Alarms main menu. 2. Use the LEFT or RIGHT 4-Way Cursor Control keys to change the Temp Alarm setting. (Off, 33-120 [Fahrenheit], 0-50 [Celsius], Default = Off)

Off Course Alarm

Off Course Alarm sounds when the boat has moved too far off course based on the menu setting when navigating. Off Course Alarm allows you to set how far the boat is allowed to move off course before the Off Course Alarm will sound.

Off Course Limits

Arrival Alarm Circle
To change the Off Course Alarm setting: 1. Highlight Off Course Alarm on the Alarms main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Off Course Alarm setting. (Off, 25 to 3000 feet, 10 to 1000 meters [International Models only], Default = 300 ft, 100 m)

Arrival Alarm

Arrival Alarm sounds when the boat has either exceeded the distance to the destination waypoint, or has entered the Arrival Alarm Circle, based on the menu setting when navigating. Arrival Alarm allows you to set how close the boat must be to the destination waypoint before the Arrival Alarm will sound. To change the Arrival Alarm setting: 1. Highlight Arrival Alarm on the Alarms main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Arrival Alarm setting. (Off, 25 to 3000 feet, 10 to 1000 meters [International Models only], Default = 150 ft, 50 m) 73

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)

User Mode

User Mode sets the menu system to either Normal or Advanced. When set to Normal (default setting,) only the basic menu options are shown. When set to Advanced, additional menu choices are available. To change the User Mode setting: 1. Highlight User Mode on the Setup menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the User Mode setting. (Normal, Advanced, Default = Normal)

Triplog Reset

Triplog Reset resets the Triplog to zero, 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. The Triplog provides the following information: timer for elapsed time, distance traveled since last reset, and average speed.
NOTE: See Setup Menu Tab: Select Readouts (Advanced) to find out how to display Triplog information on the screen.
To Reset Triplog: 1. Highlight Reset Triplog on the Setup menu. 2. Use the RIGHT 4-WAY Cursor Control key to initiate Triplog Reset. 3. The Confirm dialog box will appear. To reset the Triplog, press the RIGHT Cursor key once more. To cancel Reset Triplog, press the LEFT Cursor key.

Restore Defaults

Restore Defaults resets ALL menu settings to their factory defaults. Use this menu choice with caution! To Restore Defaults: 1. Highlight Restore Defaults on the Setup menu. 2. Use the RIGHT 4-WAY Cursor Control key to initiate restoring defaults. 3. The Confirm dialog box will appear. To reset the defaults, press the RIGHT Cursor key once more. To cancel Restore Defaults, press the LEFT Cursor key.

Select Readouts

(Advanced, Sonar view only)
Select Readouts sets individual digital readouts on the Sonar View. This Advanced feature allows you to select what data will be displayed in each of 5 fixed-position data windows arranged around the left and bottom edges of the Sonar View screen, or whether a particular window will be turned off, displaying nothing in that area; you can access this menu choice only when in Advanced User Mode (see Setup Menu Tab: User Mode.)

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 PLUS, 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-Press Menu: X-Press Menus are a Humminbird feature that make the most commonly-used menu selections available with one press of the MENU key. Items that appear on the X-Press Menu are related to the current view, and present the most logical choices for that view. Sonar View X-Press menus will differ from Chart View X-Press menus, etc. X-Press menus are one of the principal reasons that Humminbird products are easier to use. 99

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.
