I've had an Garmin eTrex Vista for about a year and love it. THEN, I started Geocaching. Here in the Pacific Northwet we have lots of heavy tree cover in our forests. While hiking on trails it is not a big deal to loose satellite reception for a couple of minutes. You can still navigate to where you are going, and more inportantly, you can navigate your way back to your vehicle. While Geocaching, it is not acceptable to loose satellite reception. The GPS V does a great job under heavy tree cover because of the antenna type vice the patch antenna on the Vista. AND it is great for turn-by-turn directions in the vehicle to get you to the cache site. My wife was always getting us going in the wrong direction, or lost, using a map and telling me where to turn. The GPS V is a much better navigator than my wife. Also cuts down on the yelling and screaming inside the vehicle.
