The Polar Vantage V is a multi-sport and triathlon watch for the true athlete. The Vantage V features advanced software to calculate the intensity, load, and recovery of your workouts. In addition, the Vantage V measures your sleep duration and quality, so that you know whether you've recovered from your training at night. You'll receive training advice based on this physical data and your goals. That way, you'll know exactly when to slow down a bit and when you've recovered enough for a heavy workout. The watch also calculates your VO2 max and running power, so you won't overdo it during a competition. The sports watch will help you find the right balance.
Note: it doesn't come with a charger. Want to charge the watch using a power outlet? Make sure to order a separate charger.
