Amazon.com Product Description
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.

This was the first HRM I owned, and it is perfect for beginners. Everything is very simple to understand, and set up. The unit is attractive looking, and highly accurate (you can see your HR rise the moment you start moving), with enough real features to keep you motivated, and actually put it to good use either in the gym or on the road.
One thing I've since discovered, is that Polar HRM's are much easier to use than some other models (check a few manuals online to see for yourself). The F4 is very simple: simply enter some initial data (age, sex, weight), and then put the strap on (wet the reverse with some tap water) and you're ready. Click the start button. The unit has useful exercise views (duration, time in zone, calories, avg heart rate, max heart rate) which you can cycle through with a button press as you work out. Once finished, you view an exercise summary screen, which displays all this information. The data is then added to a totals file (which can be reset at will -- ie: at the end of the week).
All in all, this is perfect for a beginner. It does enough for it to be useful for a couple of years, before you will want to move onto something more complicated. Don't spend £150+ on a HRM first time; try something like this and make sure you need extra features. This worked like a dream for me, and I'd recommend it to anyone looking for a simple (but effective) heart rate monitor.

works just like it should. accurate. easy to read. i love it!
By Michael P Mccullough (Klamath Falls, Oregon, USA)
Read the manual. One reviewer complained that it beeps constantly - she should have reset her target zone. I lamented that it kept reading too high, or became stuck on one heart rate even if I sprinted or stopped, or it displayed just zero zero. I discovered (by reading the directions)that I needed to turn my Blackberry off. It works fine if my phone is off!
