To give you an idea of what I am dealing with, this is the boat I use it on. No waves to hit, I am in ponds. In Humminbirds defense, I am using this 798 in a fashion it was not really meant, I have made it portable. Easy on easy off the boat. This thru hull transducer will stop that for sure, (it will be more permanent) but I just cant seem to find the right spot doing it the way I am doing it now so....

As far as repairs or holes, not really worried about that. I own a boat company and built this boat so welding up a hole if the transducer doesn't pan out wont be an issue. I am just looking for something that works better.

Greg, I have downloaded the upgrade, but I see you saying to do it again? Howcome?
