down the total range (for example, in 20' (6m) of water, the 0-30' (0-10m) range would be selected). This provides the best display resolution and therefore the best target separation possible.

The Depth Range can be adjusted manually. Press MENU repeatedly until the Depth Range menu is visible. Two options are available: Auto and Manual.

The manual setting enables you to

adjust the current depth range setting. The unit no longer adjusts the Depth

Range to the most appropriate range

for bottom display. Often, the bottom may not be visible on-screen. The digital depth readout 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.

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 display resolution is increased, and the unit’s ability to separate close targets is enhanced.

There are four Zoom ranges available: 7¹⁄₂' (2m), 15' (5m), 30' (10m), and 60'
