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.
