My Echomap came with a GT51M-TM transducer with frequencies of 260/455 kHz Chirp SI\DI. Which would be the best setting for 20' of water side scan detail images? The 800 kHz images on some of this sites images look very clear.

455 shows best on my 73sv chirp which came with 455 and 800
I do the best with 455 on both dv and sv. Some say 800 is better for soft targets. I have tried it a few times, wasn't crazy about it.. I'm really just looking for cover mostly and am happier with 455. Find the cover with this, find the fish with 2d. btw I am usually in less than 15 fow, and am using a 93sv chirp.
