This is a wonderful gadget. It is aimed at athletic training, and it's ideal for that, but it's also a great companion for hiking, sailing and generally not getting lost (e.g. strange city, wilderness trek). It's not too clunky to wear and the battery should last for an all day hike. The Garmin software does a good job of keeping track of workouts and SportTracks software ([...]) will give the same plus a nice plot of your travels on a map or satellite image. People seriously into training should get the heart monitor 305 version or one of the later products but, otherwise, the 205 does everything I want.
