tgat77,
I live in Tn as well and I have a question for you. I am fairly new to owning a decent bass boat with electronics, so hopefully this wont sound to stupid. I have the Elite 5 HDI on console and Mark 5 up front. Are the Lake Cards worth the money? I plan on fishing some of the same lakes you listed. Holston and Cherokee are my closest lakes. (not counting Boone, which has no water) The GPS works really well and I have bought all the paper maps with Lats. and Longs so I can use those. I am hesitating on spending 170 to buy the card with the maps on it and I dont see myself doing any sonar logging to create my own maps anytime soon. Any advise from anyone would be great.
