Summary: I purchased a yellow Garmin eTrex GPS about a year ago. My main reason for buying it was because I learned about the sport called 'geocaching', and, knowing little about these devices at that point, I purchased one on the advice of a couple of friends. I used it heavily for for about 5 months before coming to some conclusions about this device's capabilities. I will first list the yellow eTrex's good points: - It's cheap-- one of the cheapest GPS receivers you can find.
Summary: I bought one of these units because of its waterproof rating. That is 30 minutes at 3.3 feet. Forget that one. The battery compartment isn't rated for this.....so it leaks big time. I called Garmin about this and they said that nothing can be done. There is no fix. This was December 2000. Since it eats batteries, I bought a Radio Shack digital camera battery kit. It has 4 ni-mh batteries rated at 1500mah and a chargerfor $22. This unit worked very well.
Summary: I was really happy for about the first couple days having the etrex. Its very realiably built and simple. After about four days having it however, I realized that it really is a waste of money. Taking it hiking is just not really fun... The etrex is a little over simple. Your better off paying a little extra for a MUCH better GPS. If your like me (one who likes gizmos), you will get bored of the etrex in a very short amount of time.
Summary: Please be aware that this is the older model. The high sensitivity newer model is only £1 more expensive and is WAAS enabled. The difference in accuracy and tracking of satellites is dramatic. Used the newer version for Geocaching and could locate the caches easily to sometimes even less than 1m! Buy the high sensitivity version instead.
