I've had several GPS over an 8yr period the one I have now is the best I've ever had. This is the garmin etrex summit, I'ts digital, which means you do not have to move to get an accurate reading. Don't think that's not a big deal, because it is, other wise you have to use a compass to get a reading, say if you stopped to take a snack and take a reading at the same time, in order for it to read accuratley you must use a compass along with GPS. I've had several magellan GPS they last about 2yrs each and had to be replaced. This garmin is great, but like someone else metioned do'nt waste money on features you'd never use. The garmin sell's for 179.00 after rebate. elknut1
