I waited a couple of months til I could afford the Terrova I-Pilot and love it. It really is like having an extra person on board to steer the boat. I was trolling for crappie when a 21" striper hit one of my minnows. I was in a narrow section of a creek where other boats were fishing. I hit the anchor lock and was able to play the striper in without drifting into other boats or the shore.
The compass and speed controls are really good for trolling or working an area.
Get the IPilot Terrova and you will never regret it.
