Sonar Depth Log If you are using a depth-capable transducer, or are receiving water depth information via NMEA 0183 or NMEA 2000, the Depth Log displays a graphic log of depth readings over time. The depth appears in the upper-left corner of the screen. The graph scrolls to the left as information is received. From the Home screen, select Sonar > Depth Log. Setting the Depth Log Range and Time Scales You can indicate the amount of time and the range of depth that appear in the depth log. 1. From the Home screen, select Sonar > Depth Log. 2. Select Menu. 3. Complete an action: • Select Duration to set the time-elapsed scale ➊. The default setting is 10 minutes. Increasing the time-elapsed scale allows you to view depth variations over a longer period of time.
