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
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.
