Sonar screen on jon boat

[wiperhunter2]

This might not be what you had in mind but one of the guys I fish with all the time (wiperslayer), put a set on his boat that might work for you. He installed a pole holder mount, the kind that holds your pole while trolling, on the side of his boat, then he cut off the top of the pole holder, leaving just the part that goes into the mount. The base of the pole holder was then mounted to the bracket for the finder. The advantage of this system is that it can be easily removed and you might be able to buy a ram mount that will do the same thing. I can get some pictures of this set up if your interested.
