TVG Setup dialog box
When an acoustic pulse is sent through the water, it will gradually lose its energy. The
greater the distance between the transducer and the target(s), the greater the loss of energy.
TVG
(Time Variable Gain) compensates for the loss of acoustic energy due to geometric
spread and absorption.
