Thanks Guys, I knew I could count on you to help me keep spending my children's grocery money. The reason I asked the question is to help figure out which one to buy for pulling cranks without buying more than I need. It sounds as if the auto-pilt will keep me going straight while I tend to rods/fish etc. The co-pilot will allow me to control the motor and make course adjustments from anywhere in the boat and I-Pilot will do all of the above plus more than I will ever use.
Now what about the PD V2 vs Terrova-- any comments?
