Sorry but, I just have to jump in here.
I bought my first MK PowerDriveV2 with iPilot factor installed when they first came out. For me, it just didn't work out. I fish only brushpiles and MUST stay on top of the to catch crappie. The ad for the iPilot claimed a 5' radius but 50' was more like it. Complained to MK and they had me take it to their factory approved repair in Dallas. All Star Marine were great guys to work with and after 3 weeks wait to get all new electronics for the PDV2 I got it back on my boat and it worked better but not even close to 5' radius.
Sold the PDV2 when the iPilotLink was announced and bought a new Terrova before the Link started shipping. I also made the switch from Lowrance to HB 1198 and 998 to take advantage of all the iPilotLink features.
Long story short, none of this worked as advertised, sold it all and purchased a MK Fortrex and new HDS's, a 9Touch for the console and one for the bow.
I would NEVER buy another electric steer tm. They are too slow to respond and much noisier than cable steer.
And, in my opinion the iPilot and iPilotLink are NOT good for crappie fishing, at least the way I fish. Bass guys and other types may be able to live with them but, I can't.
