Drop me a PM also if you would like, I have had mine for over a year now. I should work for humminbird because everyone ends up getting one after fishing with me. Hardest part is knowing what you are seeing, and don't do what I did. When I first installed it, somehow or another I shut off one of the frequencies for the transducer. I never got those "pretty" arches and finally figured it out by READING THE MANUAL!
