I really like this watch. It's a very nice digital watch. The barometer and altitude functions are interesting, and basically useful. However, the altitude function is not useful for golf, I have found. The accuracy is to 20 feet, and takes time to adjust. It is not precise enough for golf. Perhaps if I was using it hiking, it would be accurate enough. At around $50, it is a nice digital watch that is pretty cool. Otherwise, don't expect to be able to use it to measure elevation changes on the course.
