Now that fall is on it's way, I'm looking to finally get my boat rigged with a trolling motor. I've got the 24 volt setup and have been looking at the power drive 70 from minnkota. Do any of you recommend this motor? Is it worth the money to get the co-pilot for a 16' open tiller style boat? It will be used mostly for river jigging. Also, I've got a nice Garmin unit on the back of the boat, in your opinions would it be beneficial to have the US2 option to possibly put another graph at the front of the boat or because it's only 16'long I'd get interference between the 2 fish finders. Thanks in advance!
