I always feel like a pessimist when I buy stuff because it always fails me. So far, my latest Terrova hasnt failed me. Ive only had it for 2 months though. I have the crappiest (no pun) luck with them dang trolling motors. Better than MG I guess. I thought mine was broke when I tried the I-Pilot features. Thought they had sent me a screwed up system again. I wanted to anchor with it and stay near the school. It moved way too much to be used as an anchor. I called them and they said it was normal behavior. It turns off when it gets close to the spot and then drifts away. I saw a GPS Anchor ( RHODAN MARINE SYSTEMS HOME - INVENTORS OF THE ORIGINAL GPS GUIDED TROLLING MOTOR ) at a show in Tampa and it actually sat still with no anchor. I think they charge a lot for their system but it is impressive. Not sure if I could afford it.
