I'm thinking of buying the new Humminbird 597ci HD DI Combo from bps. Thinking of puting it on a ram mount at my console and running it with a switch to swap from the transom to the TM (Just spinning it when I get up to fish). I really want something that has GPS, color, and I really like this new down imaging. What are your thoughts? I'm going to pull the trigger on something the first week of February.
