As for the structure scanning doesn't the ducer have to be in the water, not shooting through the hull?

I'm looking to upgrade here soon and haven't quite jumped fully at the DI systems yet.

as far as di i have only used the unit once. di is nice but i can see being bent if thats all you have. in lj 60-130 ft of water i had the ducer set to 455khz(not the best quality) it was ok.800khz (best quality) looked like s**t. it might need some tweeking to fix though. time will tell. conventional sonar was great. overlay of both is nice 2.

imo i would not buy a di only unit.
