Setting the Gain–Screen #1
The gain is also referred to as sensitivity, and ranges
from 0 to 25. The factory default setting of 15 usually
provides excellent results. The gain control only has
an effect on the probe function. Most of the time no
or only small adjustments are necessary. Increasing
the gain allows probe readings to be received from
greater depths. Lower gain settings reduce the pos-
sibility of other sonar or electrical interference, and
also may be necessary in shallow water
