Pontoon Boat & Deck Boat Forum

I bought a humminbird 597 ci HD DI combo and am interested in the Navionics countour map chip but can't decide on the Navionics Hotmaps Inland East Coast or the Navionics Gold (Coastal USA and Bahamas). I will be boating in the upper chesapeake, C&D canal, and possibly middle Delaware River. The products themselves are not fully descriptive whether they include it or not.

Does anyone in my area (Delaware/Maryland) have either chip and can you let me know which to purchase?

(Update - 5/7/2013): The Hot maps premium East has the Chesapeake bay on it with the contours and depth readings with obstructions (some) and soundings in case anyone is interested. The humminbird 597 is awesome by the way.

FYI, if you were not aware, Humminbird now owns Lakemaster and the new I-link system will automatically lock on to the contours on their maps, and follow them, might want to consider that. I have not really looked at the lakes available as they only have US maps at this time and I am in Alberta.
