Figure 13 - Omni / Vertical (option)
The Omni / Vertical mode is specially made for trawling, where
a complete overview of the horizontal and vertical situation is
presented.
The bearing of the vertical slice on the right-hand side is as in
180°/Vertical mode indicated by the white audio line, while the
slice on the left-hand side in this mode is indicated by a
long- dashed line. This left- hand slice can be selected with the
gear button to be an 180° extension of the audio line, or to be
locked to the trawl symbol.
The normal tilt indicator is here replaced by the digital readout in
the centre on the top of the display, this to give more space for the
echo presentation.
The catch data page for trawling is selected in the menu field.
Here the trawl position is presented in relation to the target, and
this can be used as a sight in order to optimize the catch. In
addition to showing the trawl position this page also shows all
available target data.
