I bought this one 3 years ago for geocaching (geocaching.com) and for my hiking trips. It has never let me down when I needed it. I have dropped it in creeks and in a lake (backpack with it in it sank to 10 feet for over 4 minutes) and it started up without a glitch. Reason I gave it a 4 is because the receiver is a little weak. If you are in a canyon or heavy foliage or trees over you, you will lose satellite reception. But if you can find a little opening, you are back in business again.
