Sonar Gain
The gain controls the sensitivity of the hardware
receiver. A higher gain makes the sonar more
sensitive to echo returns, allowing it to display
weaker targets.
If the gain is set too high, the image might be
cluttered with background noise.

: when set in [shallow water mode], the
[Gain] option will be disable.
