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.

How to open

Note

Each sonar application has its own TVG profile. Before changing the TVG settings, select
the sonar application you want to configure from the
