Our Comment

A great way to keep the motivation going during those long winter evenings. The Garmin Forerunner 405 is a sophisticated sports watch and feature-rich personal trainer. The GPS-enabled watch tracks your training, then wirelessly sends your data to your computer so that it can be analysed and shared with others.

We have been testing this watch on a regular basis over the last three months and it is definitely one of, if not, the best sport watch currently available on the market.  You will not be disappointed with this GPS unit.
