I am looking for a garmin map that would help with navigation(topographical) off shore in the gulf coast are. Pensacola etc. We vacation there often. We will be getting a new boat and don't want to worry about getting lost!EEEEK! yet still be able to find some good dive spots etc. Anyone know of any map that will help with this? Sorry if I'm a newbee and this is a dumb question. I just want to find something that will work. Using Windows mobile. I am downloading the U'S. topo's but don't know if they alone will be enough?

Somebody help out a newbee will ya?
