They want me to send it back for repair, but this is the time of year I use it most. It's an inconvenience I was trying to avoid by buying what I thought was an upgrade from my old FF. Fished two tournaments now with no console FF in the last couple weeks. GPS works fine, but worthless if I can't see what I'm marking. Now I have a couple weeks between tourneys so I guess it's going in for service. Still not happy about having a 4 month old unit fixed. Replacement or refund would seem more fair to me, but whatever I guess. Really makes my plans for a HB SI later in the year a little less certain. Might have to look at the Lowrance now I guess.
