Installation manual

Simrad SH80
Dual 1
The Dual 1 mode is a kind of “two sonars in one” operation, where
each presentation is updated for every second transmission. All
settings can be set individually for each of the two presentations.
This makes the dual mode especially useful for optimizing
settings by directly comparing the two presentations.

To optimize the horizontal settings, use the Horizontal menu to
try different settings in the upper picture. These settings are
automatically transferred to the other modes. The dual operation
may also be used for other user applications, where different
range, tilt, frequency and other parameters can be selected.
