Is this unit easy to use for someone that does not know anything about hand helds?? I am thinking of buying one of these mainly for trying to find my way out of the woods, or possible get into the game of Geo Caching, and also trying to find my hot spots so I can return to them on the water or ice. Would this be a good first time unit for me to buy?? I usually catch on to the electronics after some trail and error but I am no rocket scientist
