3.3 Selecting the Range
The [RANGE] control selects the detection (display) range, in 15 settings. Select the range
according to either the fish species being searched or the depth desired. Each time the control
is operated the newly selected range briefly appears in large characters at the screen top.
Range is permanently displayed at the top right-hand corner of the screen.
Normally the range is set so that the bottom is traced at the lower part of the screen (like an
echo sounder).
