This chartplotter is compatible with the Garmin ClearVь transducer as well as a range of accessory transducers including Garmin GT transducers, which are available at www.garmin.com . If you are connecting a transducer that was not included with the chartplotter, you may need to set the transducer type to make the sonar function properly. If the device automatically detected your transducer, this option does not appear. 1 From a sonar view, select MENU > Sonar Setup > traditional transducers or the contrast for Garmin ClearVь and SideVь/ClearVь transducers. This setting works best after you have adjusted the level of detail shown on the screen using the gain or brightness settings.
If you want to highlight smaller fish targets or create a higher intensity display of a target, you can increase the color gain or contrast setting. This causes a loss in the differentiation of the high intensity returns at the bottom. If you want to reduce the intensity of the return, you can reduce the color gain or contrast. 1 From a sonar view, select MENU . 2 Select an option: Installation > Transducer Type . 2 Select an option: If you have a 200/77 kHz, dual-beam transducer, select Dual Beam (200/77 kHz) . If you have a 200/50 kHz, dual-frequency transducer, select Dual Frequency (200/50 kHz) . If you have another type of transducer, select it from the list.
While in the Garmin ClearVь or SideVь sonar view, select Contrast . While in another sonar view, select Sonar Setup > Advanced > Color Gain . 3 Select an option: To increase or decrease the color intensity manually, select Up or Down . To use the default setting, select Default . Creating a Waypoint on the Sonar Screen Using the Device Keys 1 From a sonar view, use the arrow keys to select a location to save. 2 Select SELECT . 3 If necessary, edit the waypoint information. Adjusting the Range of the Depth or Width Scale You can adjust the range of the depth scale traditional and Garmin ClearVь sonar views and the range of the width scale for the SideVь sonar view.
Allowing the device to adjust the range automatically keeps the bottom within the lower or outer third of the sonar screen, and can be useful for tracking a bottom that has minimal or moderate terrain changes. Manually adjusting the range enables you to view a specified range, which can be useful for tracking a bottom that has large terrain changes, such as a drop-offs or cliffs. The bottom can appear on the screen as long as it appears within the range you have set. 1 From a sonar view, select MENU > Range . 2 Select an option: Pausing the Sonar Display From a sonar view, select MENU > Pause Sonar . Viewing Sonar History You can scroll the sonar display to view historical sonar data. NOTE:
Not all transducers save historical sonar data. 1 From a sonar view, select MENU > Pause Sonar . 2 Use the arrow keys. Customizing the Overlay Numbers You can customize the data shown on the screen. 1 From an applicable screen, select MENU > Overlay To allow the chartplotter to adjust the range automatically, select Auto . To increase or decrease the range manually, select Up or Down . TIP: From the sonar screen, you can select or to manually adjust the range. TIP: When viewing multiple sonar screens, you can select SELECT to choose the active screen. Numbers . 2 If necessary, select the numbers to customize. 3 Select an item to show or hide it.
Adjusting the Level of Detail You can control the level of detail and noise shown on the sonar screen either by adjusting the gain for traditional transducers or by adjusting the brightness for Garmin ClearVь transducers. If you want to see the highest intensity signal returns on the screen, you can lower the gain or brightness to remove lower intensity returns and noise. If you want to see all return information, you can increase the gain or brightness to see more information on the screen. This also increases noise, and can make it more difficult to recognize actual returns. 1 From a sonar view, select MENU . 2 Select Gain or Brightness . 3 Select an option:
Setting the Zoom Level on the Sonar Screen 1 From a sonar view, select MENU > Zoom . 2 Select an option: To zoom in on the sonar data from the bottom depth, select Bottom Lock . To set the depth range of the magnified area manually, select Manual , select View Up or View Down to set the depth range of the magnified area, and select Zoom In or Zoom Out to increase or decrease the magnification of the magnified area. To set the depth and zoom automatically, select Auto . To cancel the zoom, select No Zoom . To increase or decrease the gain or brightness manually, select Up or Down . To allow the chartplotter to adjust the gain or brightness automatically, select an automatic option.
Setting the Scroll Speed You can set the rate at which the sonar image moves across the screen. A higher scroll speed shows more detail, especially while moving or trolling. A lower scroll speed displays sonar information on the screen longer. Setting the scroll speed on one sonar view applies to all the sonar views. Adjusting the Color Intensity You can adjust the intensity of colors and highlight areas of interest on the sonar screen by adjusting the color gain for 14 Sonar
