I had a perfectly good trolling motor, and didn't really won't to buy one. but I got to reading about the I-pilot and bought one. and that was the best money I ever spent. I fish by myself most of the time. and lunching your boat with a friend, you can just back the rig in the water and pull out and go park the truck. and when you walk back to the ramp your friend can pull over and pick you up. but when by yourself, if the floating dock has a few other people tied up loading their stuff. you have to keep one ramp blocked while you wait for a spot at the dock, or tie to a rock or tree at the bank. and that isn't good for a fiberglass boat. here is one thing I like about the i-pilot, it works like a friend, when your lunching the boat by yourself. back the trailer in the water, unload boat and pull up to dock or bank and step out of boat. use the remote and troll the boat out from bank about 30 feet and push the little anchor button. it will keep it's self in a 5 ft. circle while your gone to park the truck. when you get back, use the remote and troll the boat to where you are standing and get in. the i-pilot will also mark a fishing trail, you can press the button to record a trail as you troll alone. but here is how I do it. a spot that I know I want to fish, I lower the trolling motor, so the GPS is in the up position. and loosen the knob that adjust how deep you want the prop to be in the water, pull the trolling motor shaft up so the prop is out of the water, and tighten the knob. then start the big motor. press the record button on the remote to start the trail. then drive the boat alone the trail you want to fish. it will mark the trail as fast or slow as you want to go. then stop and lower the trolling motor back down in the water and fish the trail from end to start or from start to end. and set the cruse control for ever how fast you want to fish, and you don't have to do a thing but fish. the i-pilot will follow the trail just as you marked it. and when you hook up with a fish, press the anchor button and the i-pilot will hold the boat in the 5 ft. circle until you land the fish. don't have to worry about drifting near the bank or drifting out into the lake while fighting the fish. you stay where you pushed the anchor button. thought this might help some of you guys that fish alone like me, and it does so much more, but I've written a book already.
