Im sorry, but for some reason if I try to add a new topic/reply I cant add a message, just a title. Any help on that issue would be appreciated. Im getting ready to put a Hummingbird 797 on my 07 P-2 in the dash. I understand that most are hooking it up with 2 transducers, one on the jack plate the other through the hull. When I was looking at Cabelas I noticed it was not offering a thru-hull option for the 797, only the bigger models. Does that mean I wont be able to use the sonar while running, just when Im putting around? That would be a problem for me. Also, has anyone had expierence with BPS installing these. Is thier customer service for service any good? Thanks, and again, Im sorry for hijacking this topic.
