always determines the depth of the bottom, even if it is not visible on-screen.

Using manual Depth Range control, you can view sonar information from the area near the surface in great detail.

To return to automatic Depth Range control, press the MENU button until the Depth Range menu appears on- screen and use the UP ARROW to select AUTO.

Depth Range

Zoom. Zoom is similar to Depth Range because it controls the range of information displayed on screen. Zoom, however, allows selection of ranges beneath the surface so any area of water between the surface and the bottom can be enlarged to provide more detailed information. By using the full display to show a small area of coverage, the effective dis- play resolution is increased, and the unit’s ability to separate close targets is enhanced.

Upper Zoom Limit

There are four Zoom ranges available: 7¹⁄₂' (2m), 15' (5m), 30' (10m), and 60' (20m). These ranges are not directly user controlled but are instead dependent on the current depth range. In shallow water, when the 15' (5m) or 30' (10m) range is in use, the Zoom range is 7¹⁄₂' (2m). If the 60' (20m) or 120' (40m) range is in use, the Zoom range is 15' (5m), if a 180'-480' (60-150m) depth range is in use, the Zoom range is 30' (10m), and if the 600' (185m) range is in use, the Zoom range is 60' (20m).
