Range

The Range parameter can be accessed from the button in the

Horizontal and Vertical menus.

Horizontal and vertical range is normally selected using

the SH80 Sonar Operating Panel. You can also control

these settings directly on the Rangebutton. The available

choices are listed in this dialogue.

The Range buttons are described in the Sonar

Operating Panel chapter.

Available ranges (in meters) are:

50, 75, 100, 150, 200, 300, 400, 500, 600, 750, 1000,

1200, 1500 and 2000.

In addition to the readout on the menu, the current

horizontal range is normally displayed over the tilt

indicator in the upper, left-hand corner of the display.

The following options are available in the Range parameter

dialogue:

Manual - Allows you to change the range manually.

Auto - Enables automatic range selection during position- and

target tracking. This allows for optimal tracking.

To maintain a steady display during seine setting, the lower

automatic range is set to 450 meters. Changing the range or

pressing the Manual buttons will stop the automatic ranging

function.

The SH80 sonar is designed to work with various horizontal

range units such as meter, nautical mile, US survey feett or

yards. This choice can be made by pressing the Units button in

the Display menu.
