TVG (Time Variable Gain)
The TVG function controls the gain of the receiver so that a
school with a given size and density is presented with
approximately the same strength on the display, inside the
regulatedTVG range. This can alsobe seen as a filter, because
it reduces the noise close to the vessel.
