Just got off the phone with Minn Kota customer service and the lady tells me there is an upgrade available for the Ulterra that will make the spot lock hold much closer to the "spot" when you lock it in. Its only $500. Wow Mine is only about 9 months old-what a rip! A $500 up-grade to make it do what it was supposed to do when it came out. I was told it would hold to a 5 ft. radius and I would be very happy with mine if it would do that!
