I don’t have the Dff3d sidescan, just the sidescan transducer hooked up to the tzt3. I was going to try the Dff3d, but was informed here that if I was fishing mostly in 75-150’ just to try the sidescan transducer.
Silly me, you are absolutely right. You have the CHIRP Side Scan displayed on your TZT3. I did not look carefully enough and mistook the CHIRP Side scan presentation for the DFF3D Side scan.
My bad...
Yes, at those depths I would utilize the CHIRP Side Scan.
