The 500 SeriesTM Fishfinder uses sonar to locate and define structure, bottom contour and composition, as well as depth directly below the transducer. Your 500 SeriesTM Fishfinder 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. 1 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. 2 Single Beam Sonar Your Humminbird® 515, 525 or 535 Fishfinder uses a 200 kHz single beam sonar system with a 20° area of coverage. Depth capability is affected by such factors as boat speed, wave action, bottom hardness, water conditions and transducer installation. DualBeam Sonar (565 Fishfinders only) Your Humminbird® Fishfinder 565 uses a 200/83 kHz Dual Beam sonar system with a wide (60°) area of coverage. DualBeam sonar is optimized to show the greatest bottom definition using a narrow (20°) beam yet can still indicate fish found in the wide (60°) beam when the Fish ID+TM feature is turned on. DualBeam 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. NOTE: It's important to note that your 565 Fishfinder is a DualBeam-only unit and should not be confused with the DualBeam PLUSTM functionality of the 575 Fishfinder. DualBeam will only show hollow fish symbols from the wide 83 kHz beam when Fish ID+TM is turned on. You cannot view the 83k Hz sonar information separately from the 200 kHz sonar information as you can in a DualBeam PlusTM 575 Fishfinder unit. 3 QuadraBeam PLUSTM Sonar (575 Fishfinders only) Your Humminbird® 575 Fishfinder supports QuadraBeam PLUSTM sonar. QuadraBeam PLUSTM sonar provides an extremely wide 90° area of coverage. QuadraBeam PLUSTM starts with two fan-shaped 35° 455 kHz Side Structure locating sonar beams to spot fish, bait and structure to the left and right of the boat over an area of the bottom that's always equal to twice your depth. QuadraBeam PLUSTM finds more fish faster, and can even tell you where to put your bait by showing if fish are to the left, right or directly beneath your boat. For structure directly below your boat, Quadrabeam PLUSTM uses a DualBeam PLUSTM 200/83 kHz 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. 4 What's On the Display The 500 SeriesTM Fishfinder can display a variety of useful information about Depth - water depth; can be set to alarm when the water becomes too shallow. Speed - if a Temp/Speed accessory is attached, your Fishfinder can display the speed of the boat, and can keep a Triplog of nautical or statute miles traveled. Temperature - water surface temperature. Timer - elapsed time with Temp/Speed Accessory. Distance - distance traveled with Temp/Speed Accessory. Average Speed - average speed reading with Temp/Speed Accessory. Bait Ball Hard Bottom Rocky Bottom 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. NOTE: Entries in this view that list (with Temp/Speed) are available only if the optional-purchase 5 the area under and adjacent to your boat, including the following items: 83 kHz, Wide Beam Hollow Fish Symbol (ONLY available on Dual Beam Units) Structure - where fish may be hiding. Fish - fish are displayed as arches and/or fish icons, and the unit can be set to alarm when a fish of a certain size is detected. When a target is detected and Fish ID+TM is on, a Fish ID+TM symbol with depth is displayed. The size of the symbol shows 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, Narrow Beam Shaded Fish Symbol 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 gray levels moving across the display at the same depth. Soft Bottom RTS® (Real Time Sonar) Window Battery Voltage - the voltage of the boat's battery; can be set to alarm if the voltage falls below a certain point. device is connected to the Fishfinder. 6 Views The views available on your Fishfinder are: Sonar views: · Sonar View · Zoom View · 200/83 kHz Split Sonar View (575 Fishfinder only) · Big Digits View · Side Beam View (575 Fishfinder only). NOTE: When you change any menu settings that affect the sonar, the view will update immediately (i.e. you don't 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 quickly alternate between the two viewing methods. 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. 7 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-PressTM Menu). Six additional Digital Readouts display information from optional-purchase accessories. These information boxes can be customized to show only the information desired (see Setup Menu Tab, Select Readouts). Sonar View Depth Temperature Triplog Upper Depth Range RTS® Window Sonar History Window Lower Depth Range NOTE: If the Depth number is flashing, it means that the unit is having trouble locating the bottom. This usually happens if the water is too deep, the transducer is out of the water, the boat is moving too fast, or for any other reason that the unit can't accurately receive continuous data. 8 Understanding Sonar History It is important to understand the significance of the display. The display does NOT show a literal 3-dimensional representation of what is under the water. Each vertical band of data received by the control head and plotted on the display represents something that was detected by a sonar return at a particular time. As both the boat and the targets (fish) may be moving, the returns are only showing a particular segment of time when objects were detected, not exactly where those objects are in relation to other objects shown on the display. Real Time Sonar (RTS®) Window A Real Time Sonar (RTS®) Window appears on the right side of the display in the Sonar View only. The RTS® Window always updates at the fastest rate possible for depth conditions and shows only the returns from the bottom, structure and fish that are within the transducer beam. The RTS® Window plots the depth and intensity of a sonar return (see Sonar Menu - RTS® Window). The Narrow RTS® Window indicates the sonar intensity through the use of grayscale. The grayscale used matches the bottom view grayscale setting used in the sonar history window (i.e. Inverse, Structure ID®, WhiteLine®, Bottom Black). The depth of the sonar return is indicated by the vertical placement of the return on the display depth scale. The Wide RTS® Window indicates the sonar intensity through the use of a bar graph. The length of the plotted return provides an indication of whether the return is weak or strong. The depth of the sonar return is indicated by the vertical placement of the return on the display depth scale. The Wide RTS® Window does not make use of grayscale. 9 Bottom Presentation As the boat moves, the unit charts the changes in depth on the display to create a profile of the Bottom Contour. The type of bottom can be determined from the return charted on the display. A Hard Bottom such as compacted sediment or flat rock appears as a thinner line across the display. A Soft Bottom such as mud or sand appears as a thicker line across the display. Rocky Bottoms have a broken, random appearance. 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 Inverse (default), WhiteLine®, Structure ID®, or Bottom Black. See Sonar X-PressTM Menu: Bottom View for details on how to set the bottom view. 10 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. 11 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. 12 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. Sonar Zoom View Depth Upper Depth Range, Full Range View Upper Depth Range, Zoom View Full Range View Zoomed View Zoom Preview Box Lower Depth Range, Zoom View Zoom Level Lower Depth Range, Full Range View 13 200/83 kHz Split Sonar View (575 Fishfinders only) 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 and is only available on the 575 Fishfinder. 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. 200/83 kHz Split Sonar View Depth Upper Depth Range 200 kHz Sonar History Window 83 kHz Sonar History Window Lower Depth Range 14 Big Digits View Big Digits View provides digital data in a large, easy-to-see format. Depth is always displayed. Readouts for temperature, speed and Triplog information are displayed automatically if the appropriate accessory is connected to the system. The Triplog shows distance traveled, average speed, and time elapsed since the Triplog was last reset. The digital readouts in the Big Digits View cannot be customized. Big Digits View Depth Timer shows the time elapsed since Triplog was last reset. Distance is the distance traveled since the Triplog was last reset. Voltage displays the battery voltage. Average Speed shows the speed since the Triplog was last reset. Temperature Speed 15 Side Beam View (575 Fishfinders only) Side Beam View shows sonar information from both the left and right 455 kHz beams and the 200 kHz down-looking beam in one view and is only available on the 575 Fishfinder. You can customize the way the sonar data is displayed in the Side Beam View to suit your personal preferences. Depending on the layout selected from the Quad Layout Sonar X-PressTM menu (only available on the Sonar X-PressTM menu when in Side Beam View), the display will represent the same sonar data in one of the following three layouts: Default layout: The top portion of the display presents a historical log of sonar returns from the 200 kHz down-looking sonar beam.

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. 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, and Setup. Press the MENU key twice for the Main Menu, then use the 4-WAY Cursor LEFT or RIGHT key to select a tab, and use the DOWN or UP key to Main Menu System select a specific menu item under that tab, then Normal User Mode 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. NOTE: The Main Menu choices will vary depending on whether you are in Normal or Advanced User Mode. 22 User Mode (Normal or Advanced) - An Advanced Mode is provided for users who desire the highest level of control over the Fishfinder 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 don't have to exit the menu to apply the change to the screen). 23 Start-Up Options Menu Press the MENU key when the Title screen is displayed to access the Start-Up Options menu. 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 Fishfinder 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 Fishfinder can be used on the water. Exit Normal operation by powering your Fishfinder off. 24 Simulator Use the Simulator to learn how to use your Fishfinder 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. Simulator 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 Fishfinder 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 pre-configure your Fishfinder 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 Fishfinder off. 25 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. Exit System Status by powering your Fishfinder 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. Self Test Screen 26 Accessory Test Accessory Test lists the accessories connected to the system. Accessory Test Screen NOTE: The speed accessory will be detected only if the paddlewheel has moved since your Fishfinder was powered up. 27 Sonar X-PressTM Menu 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. NOTE: Zoom Level only appears in Sonar Zoom View. NOTE: Quad Layout only appears in Side Beam View on 575 Fishfinders. Sonar X-PressTM Menu 28 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 or 455 kHz Balance) 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 To adjust the Sensitivity: 1. Highlight Sensitivity on the Sonar X-PressTM menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the Sensitivity setting. (Low = 1, High = 20, Default = 10) 29 Upper Range (Advanced: Sonar, Split Sonar, Big Digits Views only) Upper Range sets the shallowest depth range that will be displayed on the Sonar, Split Sonar, and Big Digits Views. The Upper Range menu choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode) and can only be accessed from the Sonar, Split Sonar, and Big Digits Views. Upper Range is often used with Lower Range. For example, if you are only interested in the area between 20 and 50 feet deep, you should set the Upper Depth Range to 20 and the Lower Depth Range to 50. The Sonar View will then show the 30 foot area between 20 and 50, and will not show the surface or the bottom (assuming the bottom is deeper than 50 feet), and will show greater detail for that area between 20 and 50 feet. NOTE: A minimum distance of 10 feet will be maintained between the Upper and Lower Range regardless of the manual settings entered. To adjust the Upper Range: 1. Make sure you are in Advanced Mode, then highlight Upper Range on the Sonar X-PressTM menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the Upper Range setting. (0 to 790 feet or 0 to 257 meters [International Models only], Default = 0) 30 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. NOTE: A minimum distance of 10 feet will be maintained between the Upper and Lower Range regardless of the manual settings entered. 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 800 feet, 3 to 260 meters [International Models only], Default = AUTO) 31 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) 32 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) 33 Quad Layout (575 Fishfinders only, Side Beam View only) Quad Layout selects the method used to represent the sonar information from the two side-looking beams plus the down-looking beam to be presented on the Side Beam View, and is only available on the 575 Fishfinder X-PressTM menu when the Side Beam View is active. Use Quad Layout to change the way the Side Beam View is displayed. See Side Beam View for more information. To adjust the Quad Layout: 1. Highlight Quad Layout on the Sonar X-PressTM menu. 2. Use the LEFT or RIGHT 4-Way Cursor Control keys to change the Quad Layout setting for the Side Beam View. (Default, Classic, Slanted, Default = Default) Zoom Level (Sonar Zoom View only) Zoom Level sets the magnification level for the Sonar Zoom View, and is only available on the X-PressTM menu when the Sonar Zoom View is active. Use Zoom to increase the display resolution to separate sonar returns that are very close together. To adjust the Zoom Level: 1. Highlight Zoom Level on the Sonar X-PressTM menu. 2. Use the LEFT or RIGHT 4-Way Cursor Control keys to change the Zoom Level setting for the Sonar Zoom View. (2x, 4x, 6x, 8x, Default = 2x) NOTE: The Zoom Preview Box tracks the bottom and cannot be moved by the user. 34 Sonar Menu Tab 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. Sonar Menu 35 Beam Select (575 Fishfinders only) 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 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, and the Big Digits 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, and the Big Digits 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) 36 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. Single beam sonar FishFinders represent targets as Shaded Fish Symbols. Dual beam sonar FishFinders represent targets detected in the 200 kHz narrow beam as Shaded Fish Symbols, and represent targets detected in the 83 kHz wide beam as Hollow Fish Symbols with their associated depths. The sonar return for the Hollow Fish Symbols will not be shown. 200 kHz, Narrow Beam Shaded Fish Symbols 83 kHz, Wide Beam Hollow Fish Symbols (Dual Beam units only) When Fish ID+TM is turned off, the Fishfinder 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) 37 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 Fishfinder 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) Real Time Sonar (RTS®) Window 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) 38 Zoom Width Zoom Width adjusts the width of the Zoom window on the Sonar Zoom View. To change the Zoom Width Setting: 1. Highlight Zoom Width on the Sonar main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Zoom Width setting. (Narrow, Medium, Wide, Default = Wide). 83 kHz Sensitivity (Advanced; 575 Fishfinders only) 83 kHz Sensitivity changes the sensitivity of the 83 kHz beam and is only available on 575 models. Increasing the 83 kHz Sensitivity will display additional weak returns and decreasing the 83 kHz Sensitivity will display fewer weak returns. The 83 kHz Sensitivity menu choice is only available when User Mode is set to Advanced (see Setup Menu Tab: User Mode). NOTE: 83 kHz Sensitivity is particularly useful for adjusting the sensitivity of the 83 kHz sonar returns in the 200/83 kHz Split Sonar View. The 83 kHz sensitivity can be adjusted without affecting the sensitivity of the 200 kHz returns shown in the 200 kHz sonar window. To set the 83 kHz Sensitivity: 1. Make sure you are in Advanced User Mode, then highlight 83 kHz Sensitivity on the Sonar main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to set the 83 kHz Sensitivity. (-10 to +10, Default = 0) 39 455 kHz Balance (Advanced; 575 Fishfinders only) 455 kHz Balance adjusts the sensitivity of the 455 kHz beam and is only available on 575 models. Increasing the sensitivity will display additional weak returns and decreasing the sensitivity will display fewer weak returns. The 455 kHz Balance menu choice is only available when User Mode is set to Advanced (see Setup Menu Tab: User Mode). NOTE: 455 kHz Balance is particularly useful for adjusting the sensitivity of the 455 kHz sonar returns in the Side Beam View. The 455 kHz sensitivity can be adjusted without affecting the sensitivity of the 200 kHz returns shown in the 200 kHz sonar window. To change the 455 kHz Balance setting: 1. Make sure you have selected Advanced Mode, then highlight 455kHz Balance on the Sonar Main Menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the 455 kHz Balance. (-10 to +10, Default = 0) 40 Depth Lines (Advanced) Depth Lines divide the display into four equal sections that are separated by three horizontal depth lines. The depth of each line is displayed along the depth scale. You can either turn Depth Lines On or Off.

The lower the setting, the less surface clutter will be displayed. The Surface Clutter menu choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode). Surface Clutter To change the Surface Clutter setting: 1. Make sure you are in Advanced User Mode, then highlight Surface Clutter on the Sonar main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Surface Clutter setting. (Low = 1 to High = 10, Default = 5) 42 Noise Filter (Advanced) Noise Filter adjusts the sonar Noise Filter to limit interference on the display from sources such as your boat engine, turbulence, or other sonar devices. The Noise Filter menu choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode). NOTE: The Off setting removes all filtering; Low, Medium and High1, High2, High3 settings add progressive filtering of the sonar returns. High1, High2 and High3 are useful when there is excessive trolling motor noise, but in some deep water situations, the High settings may actually hinder your unit's ability to find the bottom. To change the Noise Filter setting: 1. Make sure you are in Advanced User Mode, then highlight Noise Filter on the Sonar main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Noise Filter setting. (Off, Low, Medium, High1, High2, High3, Default = Low) Max Depth (Advanced) Max Depth adjusts the maximum depth of operation. The performance of your Fishfinder can be tuned to the maximum depth you will be fishing in by setting the Max Depth. When a maximum depth is set, your Fishfinder will not attempt to acquire sonar data below that depth, thus increasing overall performance. When Max Depth is set to Auto, the Fishfinder will acquire bottom readings as needed (within the capacity of the unit). If the bottom is deeper than the Max Depth setting, the digital depth readout will flash, indicating that the Fishfinder cannot locate the bottom. The Max Depth menu choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode). To change the Max Depth setting: 1. Make sure you are in Advanced User Mode, then highlight Max Depth on the Sonar main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Max Depth setting. (AUTO, 10 to 800 feet, 3 to 260 meters [International Models only], Default = AUTO) 43 Water Type (Advanced) Water Type configures your unit for operation in fresh or salt water. The Water Type menu choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode). NOTE: In salt water, what would be considered a large fish might be 2 to 10 times bigger than a large fish in fresh water (depending on the type of fish you are seeking). The salt water setting allows for a greater range in fish size adjustment to account for this. Also, make sure that the Water Type is set accurately, especially in salt water, as this affects the accuracy of deep water depth readings. To change the Water Type setting: 1. Make sure you are in Advanced User Mode, then highlight Water Type on the Sonar main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Water Type setting. (Fresh, Salt, Default = Fresh) 44 Alarms Menu Tab From any view, press the MENU key twice to access the Main Menu System. The Alarms tab will be the default selection. NOTE: When an alarm is triggered, you can silence it by pressing any key. The alarm will be silenced, and will not be triggered again until a new instance of the alarm condition is detected.
