depth range. Auto mode shows the most information possible while
continuously showing the bottom.
Gain—allows you to control the sensitivity of the unit’s receiver.
This provides some flexibility in what is seen on the screen. To
see more detail, increase the receiver sensitivity by selecting a
higher gain percentage. If there is too much detail or if the screen
is cluttered, lowering the sensitivity can increase the clarity of the
screen.
