Hey midnight I got the 55thrust 48" shaft it has i-pilot and US2.. Even at 16 ft I think that will be plenty. Ive been playing with it for the last 2 days. I found out in the wind if you use a wind sock at slow speeds it works better in tracking mode. It is nice.It like Ronco, Set it and forget it!.I mounted it on quick release because some trips I make are long distance and it rides in the back of the tahoe better.I got the switch from hummingbird to go from front to back transducer. That works great.
