I am looking at buying a new depthfinder and the two units I am trying to decide on are the HB 788 ci and 597 ci. Both have the 50 channel gps and the same size screen. The pixels are the same and the power outputs are the same. Some of the features you get with 788 are advanced features that I don't know much about. Could some of you electronic guru's tell me why the 788 would be better over the 597. The price difference is roughly $130. Is it worth my money to get the 788?
Thanks for all your help,
Ringo
