Dff3d transducer gain setting

[Boneyard]

Fairly new install Dff3d and furuno transom mount xducer. Works great love it but I always like to set my gain manually on my radar and other xducer with built in sonar to the tzt3 screens. When I set manually and crank up to 100 for gain on Dff3d the bottom left of display shows manual gain at 50. I never get fuzzy returns on screen when gain all the way up like radar and other built in sonar does. Am I missing something or is it just not that powerful since it’s made to map bottom? Actually what is its transmit power 1KW?

The DFF3D output power is 800W at 165kHz. It's detection range is 200m side scan best performance and 300m directly under the boat.

Thanks for the info. Why does the max gain show 50 bottom left when it’s manually all the way up? Am I misinterpreting what I am seeing? Should I see specs across the screen like other sonar and radar shows when gain really high? Thanks
