4-3
4.3 Choosing a Range
The RANGE control chooses the detection (display) range, in 15 settings. Choose the
range according to either the fish species being searched or the depth desired. Each time
the control is operated the newly chosen range briefly appears in large characters at the
screen top. Range is permanently displayed at the top right-hand corner.
Normally the range is set so that the bottom is traced at the lower part of the screen.
