3.3 Selecting Range
The RANGE control selects the detection (display) range. Select the range according
to either the fish species being searched or the depth desired. Normally it is set so that
the bottom is traced at the lower part of the screen (like an echo sounder). The current
range is displayed on screen after the "

" indication, as shown in the figure below.
After setting a range, the newly set range appears enlarged on screen for several
seconds.
