Sitting on the sofa keying the handheld was a lot easier than doing so on the boat. I used the sinking boat icons and named the waypoints Ata001 thru Ata038 to correspond to the number system on the DNRs maps at:
Georgia Department of Natural Resources
Some attractors have been illegally moved by fisherman and you may have to search a bit to find the.
I selected the Lowrance H2O handheld because it uses the same menus and the same preloaded cards (Navionics, etc.) as my boat unit and thought I had the best shot at making it work. I think I can transfer the trails the same way but I haven't tested that yet.
Lowrance saves the downloads with a .usr extension. See if that is what your Garmin uses. Even if it is the same, I can't predict the results if you upload my file, but I'll be glad to send it to you if you want to take a shot at it.
Just let me know.
