I bought the Terrova 55BT I pilot. I like it a lot. You can hit the spot lock button and let the motor hold you in place. I use Spotlock, spotlock jog, and autopilot the most.
I bought the foot pedal because I thought I might need it for chasing down catfish jugs. It stays in the front tackle locker. The remote is awesome. You can run the trolling motor from the back deck if you wish. It made my fishing experience better.
