I had a sport pilot installed by anchor marine in erie, june 2011. This autopilot was given to my wife for a mothers day gift, ya!! she was not impressed. First time we used it she loved it, now she sits on the front and sun tans while I fish, nice. A tech from raymarine talked to me for an hour reasuring my that the bugs were worked out of the old system and this new one will work fine and it does. We mainly fish erie for walleye at 1.5 to 2.0 mph. Only down fall is that its noisy , hope you have good luck with yours.
