Have an Ultra 12 with the GT54 ducer.....12 is on console with other ducers so decided to try the GT54 with 93 Plus on the bow. With that combo, it works but you do not get the UHD frequencies, only 455 on side and 840 on clear. From the few times i tried it, works pretty good......IMO, seems to be better than the 52 at least on the clear vu compared to 800 on the 52. If i had another Ultra up there i think the pics would be alot better.....
I am working thru an issue when in shallow water About 6' or less, messes up....
Here are a few screenshots......
This one to show the few fish next to the tree
Looks to be a brush pile and tree on bottom
Coming out of a shallow cut and come across a brush pile and fish
