I think I am in the market for a different fish finder also. I have a three year old Lowrance Elite-7 chirp. Last year it would turn on with no data and had to be unplugged to turn off. I called the service department and was informed that the unit needed updating. The instructions were on their web site which I followed. The thing still won't work and I can't understand half the conversation with the service department because they don't speak or understand the English language well. I would never have bought the thing if I knew it would be this much trouble! I may be way behind the times, but do they make a fish finder that will just work without updating? Any suggestions will be appreciated!
