It just works
I'm a geek in the sense that I want to know where I've gone and what I've done on my adventures. This watch does that well, without overwhelming with a bunch of data. It won't tell you anything beyond mileage/pace/elapsed time while it's in use, but you get a GPS track of your route, elevation loss/gain, and a whole bunch of other metrics at home when you've downloaded the data to your computer. Works well and functions as a normal watch (not bulky or cumbersome like other options).
