Summary: I have used this watch on a few hiking and biking trips. The routing and tracking feature is great. Sensors and GPS are accurate. The interface with basecamp is easy. You will need to get the garmin 24k topos to really get the best performance out of the watch. The garmin topos and basecamp allow you to review a route before and after a hike. I set up a route on basecamp downloaded it to the watch and took all the guess work out of the trail.
Summary: Very good watch at very good price. This watch is valuable for those ones who like to go outdoor. It will be used for record the patch and some other information. I like this watch and will recomend my friends to buy.
Summary: Great watch. Pricey, but as accurate as the dagger used in the military. I used during a land navigation exercise, and each point had a 8 digit grid on a dog tag attached to the stake. I verified my position at each point and the watch was within ~10 meters of what was on the stake. You can set the watch to MIL SPEC UTM coordinate system, which gives you a 10 digit grid.
