Went fishing today and noticed when I use my spot lock on my Ultrex, when I try to use the buttons to reposition myself 5 feet in any direction, it just shuts the spot lock off. Everything else seems to work fine, I tried shutting the power off and turn it back on and even going back to factory default settings, no help. I can hit the anchor button and it works and holds fine, but if I touch the buttons to move it forward backwards left or right it just shuts the spot lock off. anybody have any suggestions what this might be or how I can correct it? Thank you
