I would appreciate any inputs on the Lowrance iFinder Hunt GPS. I thinking about getting a GPS mainly for hunting. I am a novice with using a GPS, but not a novice in the deep woods. The bigest option I am looking for is Topo capability, hunter type icons and larger screen that the Lowrance seems to offer. I really don't want anything too complicated. I am also conscerned with the ruggedness of the unit as well. I figure it's time to enter the 21st century. Most of my friends seem to own Garmins. Any reason for this?
