Ive been thinking about buying a small handheld gps to use on my V and maybe traveling on the road . Ive found a few on ebay fairly cheap. The lowrance ifinder GO is really cheap but dont know if it will serve my needs. As for marine use , I probley only need it to go to the Checapeake Light tower and maybe to the Gulf Stream on a flat calm day. I just need one to track my course there and get me back. what do you all suggest?
