Specifics: Serial port connection to computer; 8mb flash; I use rechargable batteries); Not water proof, although it has been through some inclement weather and has been banged around and survived.
Years of Use: 4 (Have not been inclined to upgrade.)
USES: I have used the eMap in all sorts of situations and parts of the country (NorthEast, Southeast, West Coast).
Boating: I purchased the cigarette lighter option and the mount kit (not that great, but works) for my small boat. I snap this unit in and use it to go to fishing spots (Waypoints) that I have loaded in from the software (need to purchase this as well) on my computer.
If I find new spots, they are easy to save and are automatically downloaded to the computer
Mountains: I use this for hiking, camping and hunting. Again portable and able to get to saved waypoints.
Driving: Works fine in the car. However, the screen is a bit small. Has gotten me home through backroads when others have been clogged with traffic.
