I've been looking at gps units but don't know a whole lot about them.. I realize they're accuracy is within 3 meters (not great but good enough).. Anyway heres what I'm wanting to do.. Walk our property and shoot the corners in. then shoot in points where I'd eventually like everthing to be (distances,etc) and be able to hook it to the pc and download that to a printable map.. Now the real kicker .. <$200 Is this a reasonable goal in that price range or am I dreaming?
