Marking Flat fish on the bottom

[Pete Albers]

Greetings
I have a TZT3 with a DFF3D multi beam transducer
How do I set up the sounder/plotter to mark flat fish Petrale sole in 300-500 ft of water

I don't think you can mark that with the DFF3D. What fishfinder are you using?

Maybe a white line bottom lock may pick up the fish above the line

Pete Albers,

The DFF3D does have a “White Line” function, and this allows you to easily discriminate between a hard bottom for fish that may be resting on the bottom. However, the DFF3D was designed to map structure, and the White Line feature can only display on the DFF3D’s center beam.

Also keep in the mind, that the DFF3D's beam width is 120° left to right, and a narrow fore and aft beam width of 8°.



I hope that you find this information is helpful..?
