shoot thru hull or transon mount

I just got a humminbird 596cHD DI and the transducer that came with it is for transom mount. Humminbird said that they would exchange it for a shoot thru hull transducer. This was what I had when I bought the boat back in 1995. I am kind of Leary about drilling holes in my boat, so I am thinking about the shoot through hull one. My question is, is there any difference in performance between the two, one being in the water and the other through the hull. This is a nice unit and I do want to get everything it offers, and yes I have joined the 21st century when it comes to electronics.Thumbs Up

I know that the water temp is better in the water but as far as performance I dont know. Mine is off the transom but I have to be careful of putting it on the lift.

Thanks anyway Slabmaster

Anytime you install a transducer inside-the-hull of a fiberglass boat there will be some level of signal loss. However, if you do a good job of installation this will be negligible and can usually be overcome with an increase in the Sensitivity menu.

I don’t know that I would wait on the inside-the-hull version transducer as it is the same exact transducer except that it comes with an epoxy kit instead of the transom mount hardware.

Thanks HG, Humminbird did say that it was the same transducer, so I will have it installed inside the hull where my last one was. I just wanted to know if I was losing any more features other than temp. and speed.

i have two fishfiinders one on the trolling motor and one on the transom those two little holes want hurt athing with a little silicone on them no leaks

Shoot through is far better. No issues with losing the bottom at speed, knowcing the transducer off on stumps or holes in the transom.

Im guessing you have a fiberglass boat, if you have an aluminum the transducer from the factory will NOT work. There is a ducer made that will shoot thru aluminum but I have no info on it.
