The Forerunner 405CX is the evolution of GPS-enabled training. This sleek sport watch tracks your distance, pace and heart rate, then wirelessly sends the data to your PC for later analysis. The 405CX features heart rate-based calorie computation and comes with a second wrist band option suitable for smaller wrists.
Loaded with serious training features, Forerunner 405CX continuously records your time, distance, pace, calories burned and heart rate. Each workout is stored in memory so you can review and analyze the data to see how you've improved. And advanced training features will challenge you to step up your pace — race against Forerunner's Virtual Partner® to improve your times, or set up interval workouts without having to circle the track. You even can download recorded courses to compete against previous workouts. To use the watch, simply tap the touch bezel to change screens without fumbling for a button.
Strengths: Fairly easy to set up and use. Seems rugged enough after several get-offs. Software on the PC is easy to use and has a neat link to google earth, but isn't very customizable.
Weaknesses: Bezel is a bit touchy, but nothing upsetting. One software update screwed it up, but tech support eventually provided an uninstall fix. Didn't like the standard band, but the cloth/velcro one is more comfortable. Uses heart rate strap.
I was a bit worried when I got it due to some negative reviews, but it has held up well so far other than the software glitch. Provided it keeps holding up for several more years, I would probably get it again.
