It seems when some new technology comes out I usually buy the cheapest version of something first to experiment with and then after mastering that I move on to the higer end gadgets. I would classify this GPS as one of the cheaper models at $90. But with the cheaper models usually they are easier to use and this is the case here too. There are not as many bells and whistles on this model but this is a good learning GPS.
With this unit you have the ability to track up to 12 satellites so you will never lose contact. Also the eTrex can hold 500 user created waypoints and plot a course with up to 10 waypoints to follow in opposite directions.
Some of the good points about this GPS is it only weighs 6 ounces and it is 4 inches high and 2 inches wide. It is easy to use and it is waterproof and the AA batteries will last up to 20 hours. The manufacturer claims this unit is waterproof but some reviews I have seen claim this is not true. I couldn't tell you because I haven't water tested mine and don't hope to.
Again I think this GPS is a good one to start out with but if you are really interested in geocahcing or some advanced uses you will want to move on to a higher end model soon. And make sure you look around on the internet for the best price and I'm sure you'll be happy with what it can do.
