How GPS and Cartography Work
Your 700 Series Fishing System also supports GPS and chartplotting, and uses GPS and sonar to determine your position, display it on a grid, and provide detailed underwater information. The Global Positioning System (GPS) is a satellite navigation system designed and maintained by the U.S. Department of Defense. GPS was originally intended for military use; however, civilians may also take advantage of its highly accurate position capabilities, typically within +/- 10 meters, depending on conditions. This means that 95% of the time, the GPS receiver will read a location within 10 meters of your actual position. Your GPS Receiver also uses information from WAAS (the Wide Area Augmentation System), EGNOS (the European Geostationary Navigation Overlay Service), and MSAS (the MTSAT Satellite Augmentation System) satellites if they are available in your area. GPS uses a constellation of 24 satellites that continually send radio signals to the earth. Your present position is determined by receiving signals from up to 16 satellites and measuring the distance from the satellites.
All satellites broadcast a uniquely coded signal once per second at exactly the same time. The GPS receiver on your boat receives signals from satellites that are visible to it. Based on time differences between each received signal, the GPS receiver determines its distance to each satellite. With distances known, the GPS receiver mathematically triangulates its own position. With once per second updates, the GPS receiver then calculates its velocity and bearing. The GPS Receiver included with your 700 Series Fishing System allows you to combine easy-to-use FishingGPS chartplotter and navigation capabilities with advanced fishfinding. The following GPS functionality is currently supported by the 700 Series Fishing System when it is connected to the included GPS receiver: View current position View current track (breadcrumb trail) View precision speed and heading from your GPS receiver Save tracks, waypoints and routes Travel a route and navigate from one waypoint to the next. Your 700 Series supports Navionics Gold, HotMaps and HotMaps Premium on MMC or SD card media.
NOTE: Your 700 Series does not support Navionics Classic Charts, only Navionics Gold, HotMaps, and HotMaps Premium.
Your unit also comes with a built-in UniMap with a more detailed map of North America (Domestic models) or a more detailed map of Europe and Southeast Asia, including Australia and New Zealand (International models). Your 700 Series uses the GPS Receiver to determine the position of the boat automatically, and uses the zoom level settings on a particular view to select the best chart to display. See Viewing Cartography for more information.

In all of these layouts, the sonar information from the side-looking beams reveals bottom contour, structure and fish similar to the down-looking beam, but the area covered is to the left and right of the area shown in the downlooking portion, so you actually see more of the bottom. The distance covered by the right and left beams is based on the depth setting for the down-looking beam, up to a maximum of 160 feet.

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/Side Combo View

Chart/Side Combo View shows regular chart information and side imaging sonar information in a combination split screen. You can perform some of the functions for either of these views (see Navigation X-Press Menu and Side Imaging X-Press menu for more information).
NOTE: See Side Imaging View and Chart View for more information about each side of this view.

Chart Window

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.

4-WAY Cursor Control Key

The 4-Way Cursor Control Key has multiple functions, depending on the situation: Use the DOWN or UP arrow keys to select a menu choice from the menu list, then use the LEFT or RIGHT arrow keys to change a menu setting.
NOTE: Menu choices are implemented and saved immediately - no further action is required.
In all Sonar views but the Big Digits view, pressing any 4-WAY Cursor Control key will activate Freeze Frame and will then allow you to position the cursor on the display. In the Snapshot and Recording View, highlighting a recording icon and pressing the Right 4-WAY Cursor Control key starts recording playback, and the Right and Left keys are used to control the speed of playback. In the Side Imaging View, pressing any 4-WAY Cursor Control Key will allow you to freeze the display and show the active cursor. Further presses of the 4-WAY Cursor Control key will move the active cursor to the desired location. Then press the + Zoom key to display the magnification box and the zoom level (choices are 2x, 4x and 6x). Press the + Zoom key repeatedly to display all the levels of magnification available in turn. Press the - Zoom key to reduce the magnification level. See Side Imaging View for more information. In all Chart views, pressing any 4-WAY Cursor Control key will activate the cursor.

MARK Key

Press the MARK key while in any view to mark the position of a waypoint, either at the current boat location, or, if the Cursor is active, at the current Cursor location. The MARK key only functions if you have the GPS receiver connected, or if you have enabled Screen Snapshot from the Accessories menu tab. If you have enabled the Screen Snapshot feature, pressing the MARK key still creates a waypoint, but it also captures the screen image to the optional-purchase MMC/SD card.
NOTE: You must have an optional-purchase MMC/SD card installed for the screen snapshot feature to work.
Navigation is not affected by the Screen Snapshot feature. Also, if Screen Snapshot is enabled but there is no GPS receiver connected, pressing the MARK key will capture the screen image and display an error saying that a GPS position fix is required to create a waypoint.

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-Press 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.

Sonar Colors

Sonar Colors allows you to select which color palette you would like to use for the display. To change the Sonar Colors: 1. Highlight Sonar Colors on the Sonar X-Pressmenu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the color palette. (Standard, Gray, Inverse, Green, Default = Standard)

Navigation X-Press Menu

(Navigation views only)
The Navigation X-Press menu provides access to the settings most frequently used. Press the MENU key once while in the Bird's Eye View, the Chart or the Combo View to access the Navigation X-Press menu.
NOTE: Menu choices will vary depending on system settings, such as whether you are currently navigating.

Waypoint [Name]

(Only with an active cursor on a waypoint)
Waypoint [Name] allows you to view the Waypoints submenu for the waypoint under your cursor. To view the Waypoint [Name] Submenu: 1. Move the cursor onto an existing waypoint and press the MENU key once, or use Cursor to Waypoint to select a waypoint from a list of saved waypoints. 2. Highlight Waypoint [Name] on the Navigation X-Press menu. 3. Use the RIGHT 4-Way Cursor Control key to view the Waypoints submenu, which contains the following menu choices:

Waypoint 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. 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.

Cursor to Waypoint

(Chart or Combo view only)
Cursor to Waypoint allows you to quickly move the cursor to any saved waypoint, so that you can locate it or edit it.
NOTE: This X-Press menu item appears only if you have saved waypoints.
To move cursor to a saved waypoint: 1. Highlight Cursor to Waypoint on the Navigation X-Press menu. 2. Use the RIGHT 4-WAY Cursor Control key to initiate Cursor to Waypoint. 3. Use the UP or DOWN 4-WAY Cursor Control key to highlight the waypoint you wish to move the cursor to, then use the RIGHT 4-WAY Cursor Control key to select the destination waypoint.

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 units 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

Max Depth adjusts the maximum depth of operation. The performance of your Fishing System can be tuned to the maximum depth you will be fishing in by setting the Max Depth. When a maximum depth is set, your Fishing System will not attempt to acquire sonar data below that depth, thus increasing overall performance. When Max Depth is set to Auto, the Fishing System 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 Fishing System 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 1500 feet, 3 to 500 meters [International Models only], Default = AUTO) 107

Water Type

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)

Transducer Select

Transducer Select allows you to select which transducer you want to use (the Fishing System comes with a DualBeam PLUS transducer, and also supports the optional-purchase QuadraBeam PLUS transducer.) To change the selected Transducer: 1. Highlight Transducer Select on the Sonar Main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the transducer selected. (Compact Side Scan, QuadBeam, Universal Sonar 2, Default = Compact Side Scan)

Routes

Routes allows you to view the Routes submenu. To view the Routes Submenu: 1. Highlight Routes on the Navigation main menu. 2. Use the RIGHT 4-WAY Cursor Control keys to view the Routes submenu.

Routes Submenu

The Routes Submenu contains the following menu choices: Create allows you to create a new, empty route and add waypoints to it immediately. Edit allows you to select a previously-saved route and edit its name and the waypoints on it. Delete allows you to delete a route from a list of previously-saved routes. Travel allows you to select a previously-saved route to use as the current route; this menu setting also begins navigation on this route. Routes can be traveled in either the forward or reverse direction. Info displays information about the route, including the distance and bearing from each waypoint to the next.

Chart Orientation

Chart Orientation allows you to select whether the Chart and Combo Views should be drawn North-Up or Course-Up. To change the Chart Orientation setting: 1. Highlight Chart Orientation on the Navigation main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Chart Orientation setting. (North-Up, Course-Up, Default = North-Up)
NOTE: The Chart Orientation setting does not apply to the Bird's Eye View.

North Reference

North Reference allows you to have bearings displayed with one of two orientations: True North or Magnetic North. To change the North Reference setting: 1. Highlight North Reference on the Navigation main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the North Reference setting. (True, Magnetic, Default = True)

Grid Rotation

Grid Rotation allows you to set the orientation of the trolling grid in degrees, where a setting of 0 displays a standard North, South, East, West alignment. See Waypoints for information on how to set a Grid. To change the Grid Rotation setting: 1. Highlight Grid Rotation on the Navigation main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Grid Rotation setting. (0 to 89, Default = 0)

NOTE: This feature may appear as either Trolling Grid Rotation or Grid Rotation, depending on your model.

Trackpoint Interval

Trackpoint Interval allows you to select the time period between trackpoints. The current track can only contain up to 20,000 trackpoints, so longer time periods cause the track to extend back further in time, but will be less detailed.
NOTE: Trackpoint Interval works in conjunction with Track Min Distance. Both conditions must be met before a trackpoint is added to the current track.
To change the Trackpoint Interval setting: 1. Highlight Trackpoint Interval on the Navigation main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Trackpoint Interval setting. (1 second, 5 seconds, 10 seconds, 15 seconds, 30 seconds or 60 seconds, Default = 1 second)
NOTE: During slow travel or drift, setting both Trackpoint Interval and Track Min Distance to small values will allow you to increase the track resolution.

Track Min Distance

Track Min Distance allows you to set a minimum distance of travel before a trackpoint is added to the track. The Track Min Distance menu choice is only available when User Mode is set to Advanced (see Setup Menu Tab: User Mode).
NOTE: Track Min Distance works in conjunction with Trackpoint Interval. Both conditions must be met before a trackpoint is added to the current track.
To change the Track Minimum Distance setting: 1. Make sure you are in Advanced User Mode, then highlight Track Min Distance on the Navigation main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Track Min Distance setting. (1 to 300 feet or 1 to 100 meters [International Units only], Default = 16 ft, 5 m)

Track Color Range

Track Color Range allows you to set the depth range that will be displayed as black, the deepest depth, when Color By Depth is selected as the style for the current track (see Navigation Menu Tab: Current Track). To change the Track Color Range: 1. Highlight Track Color Range on the Navigation main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Track Color Range setting. (50 to 3000 feet or 20 to 1000 meters [International Units only], Default = 50 ft, 20 m)

From any view, press the MENU key twice to access the tabbed Main Menu System, then press the RIGHT cursor key until the Setup tab is selected.
NOTE: Menu choices will vary depending on system settings such as whether the unit is set for Advanced User mode and what accessories are attached to the unit.

Units - Depth

Units - Depth selects the units of measure for all depth-related readouts. To change the Units - Depth setting: 1. Highlight Units - Depth on the Setup menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Units Depth setting. (Meters [International Models only], Feet, Fathoms; Default is Meters for International models, and Feet for Domestic models)

To change the Units - Distance setting: 1. Highlight Units - Distance on the Setup menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Units - Distance setting. (Domestic Models: Statute Miles, Nautical Miles; Default = Statute Miles; International Models: Meters/Kilometers, Meters/Nautical Miles, Feet/Statute Miles, Feet/Nautical Miles; Default = Meters/Kilometers) 134

Units - Speed

Units - Speed selects the units of measure for speedrelated 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)

Hydrodynamic noise can be overcome by proper transducer installation. Many Humminbird products have a Noise Filter menu setting that allows the user to clear the screen of noise that is difficult to eliminate. Pixels: Pixels are the "picture elements", or small square blocks, that make up the image on the LCD. Measured as a vertical by horizontal number (i.e. 640V x 320H), this key specification typically indicates the quality of resolution. In fishfinders, the total resolution (vertical multiplied by horizontal) is often less important than the "Vertical Pixel" resolution. See Pixels, Vertical. 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. 161

QuadraBeam PLUS: QuadraBeam PLUS is a Humminbird sonar configuration that uses four sonar beams for a more detailed bottom image. QuadraBeam PLUS uses the DualBeam PLUS 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 PLUS. 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 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 ultra-fast 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. 162
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. Sonar Echo Enhancement: Sonar Echo Enhancement is a Humminbird feature that describes the high degree of sonar sensitivity achieved through a combination of transmitter/receiver and software algorithms. The result of Sonar Echo Enhancement is to display virtually everything in the water that is of interest to the angler, including bait fish, game fish, thermoclines, weed beds, subtle structure, and more. Sonar Update Rate: Sonar Update Rate is the number of times per second that the transmitter/receiver sends and receives sonar signals. A very fast sonar update rate collects more information and provides a more detailed image of the bottom, fish and structure. Many Humminbird units operate at up to 40 times per second when in single frequency operation. Due to the limitation of the speed of sound in water, the update rate begins to slow as depth increases to deeper than 50 feet. In very shallow water (less than 10 feet), however, update rates as much as 60 times per second can be achieved. Speed: Speed is the rate at which the boat moves through the water. Boat speed can be measured as Speed Over Ground or Speed Through Water. Speed Over Ground is provided by GPS, and is the measurement of the boats progress across a given distance. 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 Through Water is most critical for anglers using downriggers, as it impacts the running depth of the down riggers. Speed Over Ground is optimal for navigation, as accurate destination times can be derived from this measurement. Humminbird products allow for input and display of both sources. 163

Structure: Structure is a general term for objects on the bottom that present a discontinuity and are a likely attractor for fish. This includes bottom contour features (drop-offs, humps, and holes), standing structure (stumps, timbers, brush piles) and a wide range of other potential objects (sunken boats, reefs). Humminbird units excel at showing structure with great detail over a wider area due to unique sonar configurations developed for the angler. Structure ID: Structure ID is a Humminbird feature that describes the traditional grayscale method of presenting sonar information. See Grayscale. Surface Clutter: Surface Clutter is a phenomenon where sonar returns are reflected off of tiny objects near the surface of the water, including algae and even air bubbles. Typically, saltwater environments have significantly greater surface clutter than freshwater due to continuous wind and wave action that causes aeration at the surface. The Surface Clutter menu provides manual control to bias the default settings under extreme conditions. Target Separation: Target Separation is the measurement of minimum distance that a fishfinder needs to be able to recognize two very close objects as two distinct targets (i.e. two fish hanging very close, or a fish hanging very close to structure). Humminbird fishfinders provide a very good 2 1/2 inches of target separation in shallower than 100 feet of depth. Target separation decreases as depth increases due to the need for longer Pulse Width to achieve greater depth. See Pulse Width. Thermoclines: Thermoclines are water layer(s) of distinctly different temperatures that create a sonar reflection due to the density of the differing water temperatures. Typically a thermocline will appear as a continuous band across the display at some distance above the bottom contour. Thermoclines are of interest to anglers because fish will suspend above or below the thermocline as they seek the optimum temperature and oxygen levels. Time Variable Gain: Time Variable Gain is a processing step applied to the sonar return to "normalize" the data so that objects of equal size (i.e. fish) appear to be the same size, even if they are separated by a good distance.

Humminbird Offers Innovative Side Imaging Technology In a New Compact Housing Design
EUFAULA, Ala. (July 2006) After taking the industry by storm two years ago by introducing Side Imaging technology in a consumer fishfinder, Humminbird Combo. Demand for our 900 Series Fishing Systems with Side Imaging technology has been outstanding. Anglers love the unmatched picture-like detail and coverage Side Imaging gives them, Humminbird Senior Global Product Manager Darrell Watt said. There is a group of anglers who want Side Imaging technology, but dont have the space needed to mount a big-screen 900 Series model. The 797c2 SI Combo gives them the technology in a more compact package with an ultra high-resolution color display. Side Imaging sonar provides detailed, picture-like images over a wide 160-degrees of coverage to reveal structure, fish and topography up to 480 feet of the bottom at once. This enormous coverage lets the angler search more water in less time to find the most promising areas to fish. For the freshwater angler, Side Imaging reveals fish-attracting structure such as timber, stumps, rocks and creek beds. In saltwater, Side Imaging is extremely useful in picking up precise detail of fishing structure like wrecks, reefs, humps and drop-offs, as well as spotting baitballs in open water. In each application, the detailed image helps the angler to better understand the bottom topography, type and orientation of structure to improve fishing tactics. The 797c2 SI Combo is also a full-featured traditional graphing unit with DualBeam PLUS sonar which provides both wide coverage (one sonar beam is 83 kHz at 60-degrees) and better structure and bottom detail (the second sonar beam is 200 kHz at 20-degrees). Side Imaging and DualBeam PLUS can be viewed individually or split-screen, and both capabilities are built into one easily mounted transducer.

The 5-inch color screen on the 797c2 SI Combo features hemispherical viewing for excellent readability from any angle, and a leading edge 640 vertical x 480 horizontal display resolution. 640 vertical pixels provide the highest resolution to show maximum detail from the advanced Side Imaging sonar system. The 797c2 SI Combo is designed to be either in-dash or gimbal mounted. The footprint of the unit allows it to be mounted in-dash on the majority of todays boats. It can also be mounted with Humminbirds popular Tilt & Swivel Quick Disconnect Mounting System which allows for adjustable viewing and the ability to easily connect and disconnect the unit without hassling with cables. Included with the 797c2 SI Combo is a precision 16 channel WAAS GPS receiver that plots position on a built-in, 30 meter resolution UniMap of U.S.A. inland lakes, rivers and coastal areas, or on optional Navionics Gold and HotMaps Premium charts. The memory card expansion slot on the 797c2 SI Combo can be used for Humminbirds exclusive Digital Screen Snap Shot feature. This technology provides the ability to mark a waypoint on the screen and then save the entire screen image on a memory card. The image can be reviewed later on screen like a digital camera, and downloaded to a PC for logging and trip planning. As a networkable, upgradeable Fishing System, the following capability enhancing Modules are available for the 797c2 SI Combo: InterLink allows the networking of any two Humminbird Fishing Systems (900 Series, 700 Series, Matrix Series) to share waypoints, routes and current track in real time. CannonLink allows remote operation of up to six Cannon Mag 20 DT, Mag 20 DT/HS or Mag 20 DT/TS downriggers from the 797c2 SI Combo. WeatherSense Barometric Pressure Monitor gives digital barometric pressure on the sonar view or a complete full-screen, 12-hour graph. Wireless Sonar Link extends the anglers reach to look for structure and fish wherever he can cast a SmartCast Remote Sonar Sensor up to 100 feet from the boat. Remote sonar information is displayed the Fishing Systems big screen. (more)
