Humminbird 797 Fish & CHips
I bought a Gold Fish & Chips for my Humminbird 797 c2 si, about three years ago. I thought that the chip had to be in the unit to function and did not permanently upload to the 797. Is that correct? also have there been any updates to that chip. The chip was discontinued about the time I bought it so don't know if updates have continued. Please advise.
