Kim, I bought the V2 with I-pilot so I didnt get the luxury of having both the petal and remote. But I've never seen where I wanted the petal either. YET...........anyways. The ONLY reason I would want a petal is if I had the original head unit and petal in case something happened to the I-pilot. I could switch heads and plug in the petal and keep fishing while waiting on repairs to the I-pilot. With any of 'em with I-pilot, should something ever happen with them youre gonna have to send it in for repairs som IMO youre still gonna be without a TM for awhile.
BTW, I spider rig 5% of the time and longline 95% of the time when crappie fishing and only fish for stipers & cats a dozen or so trips per year. This gives you an idea of how much of my time I send trolling and how much I depend on the I-pilot.
Err...another thought...would MinnKota warrant the freshwater tm if you ran it in saltwater?!?
