Viewing Sonar History You can scroll the sonar display to view historical sonar data. NOTE: Not all transducers save historical sonar data. Select BACK to exit history. Sonar Sharing You can view the sonar data from all compatible sources on the Garmin Marine Network. You can view sonar data from a compatible external sonar module, such as a GCV™ sonar module. In addition, you can view the sonar data from other chartplotters that have a built-in sonar module. Each chartplotter on the network can display sonar data from every compatible sonar module and transducer on the network, no matter where the chartplotters and transducers are mounted on your boat. For example, from one ECHOMAP UHD 92sv device mounted at the back of the boat, you can view the sonar data from another ECHOMAP UHD device and Garmin ClearVü transducer mounted at the front of your boat. When sharing sonar data, the values of some sonar settings, such as Range and Gain, are synchronized across the devices on the network. The values of other sonar settings, such as the Appearance settings, are not synchronized and should be configured on each individual device. In addition, the scroll rates of the various traditional and Garmin ClearVü sonar views are synchronized to make the split views more cohesive. NOTE: Using multiple transducers simultaneously can create cross talk, which can be removed by adjusting the Interference sonar setting. 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 ClearVü 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: • 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. 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 traditional transducers or the contrast for Garmin ClearVü and SideVü/ClearVü 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: • While in the Garmin ClearVü or SideVü sonar view, select Contrast. • While in a Panoptix LiveVü sonar view, select Color Gain. • While in another sonar view, select Sonar Setup > Appearance > 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. Sonar Recordings Recording the Sonar Display NOTE: Not all models support sonar recording. 1 Insert a memory card into the card slot. 2 From a sonar view, select MENU > Record Sonar. 15 minutes of sonar recording uses approximately 200 MB of space of the inserted memory card. An individual recording automatically ends after it reaches 4 GB in size. You can record sonar data until the card reaches capacity. Stopping the Sonar Recording From a sonar view, select MENU > Stop Recording. Deleting a Sonar Recording 1 Insert a memory card with sonar recordings into the card slot. 2 Select Sonar > Sonar Recordings. 3 Select a recording. 4 Select Delete. Playing Sonar Recordings Before you can play back the sonar recordings, you must download and install the HomePort™ application and record sonar data onto a memory card. 1 Remove the memory card from the device. 2 Insert the memory card into a card reader attached to a computer. 3 Open the HomePort application. 4 Select a sonar recording from your device list. 5 Right-click the sonar recording in the lower pane. 6 Select Playback. Traditional, Garmin ClearVü, and SideVü Sonar Setup NOTE: Not all options and settings apply to all models, sounder modules, and transducers. From a sonar view, select MENU > Sonar Setup. Depth Line: Shows a quick-reference depth line. Scroll Speed: Sets the rate at which the sonar scrolls from right to left. In shallow water you might want to slow the scroll speed to extend the length of time the information is displayed on screen. In deeper water you can increase the scroll speed. Range Lines: Shows the vertical lines indicating the distance to the right and left of the boat. This setting is available for SideVü sonar view. Color Scheme: Sets the color scheme of the sonar view. This setting might be available in the Appearance menu. The high contrast color schemes provide darker color assignments to the low intensity returns. The low contrast color schemes provide color assignments to the low intensity returns that are similar to the background color. Appearance: See Sonar Appearance Settings, page 24. Overlay Numbers: Sets the data shown on the sonar screen. Advanced: See Advanced Sonar Settings, page 24. Installation: Restores the default sonar settings. Sonar Fishfinder 23
