Press Menu Key to enter and switch setting page.
1) Sensitivity
There are 20 levels of sensitivity setting for user to choose
from. It greatly depends on the clarity and depth of the water.
Very clear water allows for a moderate sensitivity setting.
Conversely, dirty water requires a higher sensitivity setting
to target detail but will increase the irritating false readings.
Targeting fish in deep water generally requires higher
sensitivity, especially in dirty water. Otherwise, the sensitivity
can be lowered in shallow water. Salt and brackish water
also require a comparatively higher sensitivity setting. As
the sensitivity is enhanced, smaller details show on the
screen (but trash & debris might be detected as fish).
