Im trying to find a very afordable hand held gps unit that will let me input the listed locations where the crappie condos are located.it has to be hand held because I only have a small boat. what are you folks using and the cost of your units. it would help me very much. I have been looking at the listed locations and copying to google earth and to shows where there at. But i need something when i get on the lake to show me where to go. I dont use a smart phone so a gps app is out. thank you so much...
