Polar F4 Men's Heart Rate Monitor Watch (Black Thunder)

The F4™ Black Thunder heart rate monitor from Polar® combines all the necessary heart rate features with a new, slim design. It includes the popular Zone Pointer feature that helps keep you in your Target Zone and OwnCal® to track the calories you burn during your exercise. With a stopwatch and convenient button-free operation, the F4™ is a valuable fitness tool. A T31 Non CodedTM transmitter is included.

Featuring a new, slim design, the F4 is packed with innovative training features to help you toward your exercise goals, including:

• Zone Pointer: A visible and audible feature on the display of your heart rate monitor showing your target heart rate zone and where your current heart rate is within that zone.

• Polar OwnCal: Shows your energy expenditure during one exercise session as well as your accumulated kilocalories during several exercise sessions. You can set daily and weekly exercise goals in terms of calorie expenditure with the OwnCal feature. Because the OwnCal tracks both the energy expenditure during one exercise session and the accumulated kilocalories during a longer time (e.g. one week), it helps in achieving both short-term and long-term goals.

• Fitness Bullets: Shows a bullet on the monitor's display for every 10 minutes spent exercising/training in your target heart rate zone. The Time in Target Zone feature calculates the amount of total exercise time spent in your personal target zone. You can use this feature together with the Total Exercise Time to determine the effectiveness of your exercise program.

Key Features:

• Display of heart rate, exercise time, and average heart rate
• 24-hour clock with day/week indicator and stopwatch
• Large easy-to-read display with split screen
• One-year average battery life
• Water resistant to 30 meters (100 feet)

About Polar
The first EKG accurate wireless heart rate monitor was invented by Polar back in 1977 as a training tool for the Finnish National Cross Country Ski Team. The concept of "intensity training" by heart rate swept the athletic world in the eighties. By the 1990s, individuals were looking to heart rate monitors not only for performance training needs, but also for achieving everyday fitness goals. Today, the same concept of heart rate training is being used by world-class athletes as well as everyday people trying to lose weight. Polar is the leading brand among consumers, coaches, and personal trainers worldwide and the company is committed to not only producing the best products, but also being the leading educator on the benefits of heart rate based exercise.
