Full Sonar Chart
This is the default mode used when the Sonar is turned on for the first time or when it's reset to the factory defaults.
The bottom signal scrolls across the screen from right to left. Depth scales on the right side of the screen aid in determining the depth of targets. The line at the top of the screen represents the surface. The bottom depth and surface temperature (if the unit is equipped with a temperature sensor or a transducer with a temp sensor built in) show at the top left corner of the screen.
The FasTrack™ display shows just to the right of the scale. This changes all echoes into short horizontal bars, replicating a flasher so- nar. The zoom bar on the far right shows the area that's zoomed when the zoom is in use. (See the Zoom section for more information.)
