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. 1 From a sonar view, select MENU > Sonar Setup > Installation > Transducer Type. 2 Select the transducer to change. 3 Select an option: • If your transducer is listed, select it from the list. • 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). Calibrating the Compass Before you can calibrate the compass, the transducer must be installed on the shaft far enough away from the trolling motor to avoid magnetic interference, and deployed in the water. Calibration must be of sufficient quality to enable the internal compass. NOTE: To use the compass, you must mount the transducer on the transom or the trolling motor shaft. The compass may not work when you mount the transducer on the motor. NOTE: For best results, you should use a heading sensor such as the SteadyCast™ heading sensor. The heading sensor shows the direction the transducer is pointing relative to the boat. NOTE: Compass calibration is available only for transducers with an internal compass, such as the PS21-TR transducer. You can begin turning your boat before calibrating, but you must fully rotate your boat 1.5 times during calibration. 1 From an applicable sonar view, select MENU > Sonar Setup > Installation. 2 If necessary, select Use AHRS to turn on the AHRS sensor. 3 Select Calibrate Compass. 4 Follow the on-screen instructions. Selecting a Sonar Source This feature may not be available with all models. When you are using more than one sonar data source for a particular sonar view, you can select the source to use for that sonar view. For example, if you have two sources for Garmin ClearVü, you can select the source to use from the Garmin ClearVü sonar view. 1 Open the sonar view for which you will change the source. 2 Select MENU > Sonar Setup > Source. 3 Select the source for this sonar view. Renaming a Sonar Source You can rename a sonar source to easily identify that source. For example, you use "Bow" as the name of the transducer on the bow of your boat. To rename a source, you must be in the applicable sonar view for the source. For example, to rename the Garmin ClearVü sonar source, you must open the Garmin ClearVü sonar view. 1 From the sonar view, select MENU > Sonar Setup > Source > Rename Sources. 2 Enter the name. Creating a Waypoint on the Sonar Screen 1 From a sonar view, select MENU > . 2 Select a location. 3 Select or SELECT. 4 If necessary, edit the waypoint information, such as the waypoint name. Pausing the Sonar Display From a sonar view, select MENU > . Measuring Distance on the Sonar Screen You can measure the distance between two points on the SideVü sonar view. 1 From the SideVü sonar view, select . 2 Select a location on the screen. 3 Select . A push pin appears on the screen at the selected location. 4 Select another location. The distance and angle from the pin is listed in the upper-left corner. TIP: To reset the pin and measure from the current location of the pin, select Set Reference. 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 This feature may not be available on all chartplotter models. You can view the sonar data from other compatible ECHOMAP models connected on the Garmin Marine Network. 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 Plus 93sv device mounted at the back of the boat, you can view the sonar data from another ECHOMAP Plus 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.
