Amazon.com Product Description
Featuring a new, slim design, the F4 is Polar's first heart rate monitor designed specifically for women. It's 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.

Customer Reviews

Simple and easy
This watch is simple to use. The instructions are very easy to follow. It's fun being able to see my heart rate while I'm exercising. It works with the heart rate monitors on the equipment at my gym. I don't have to hold on to their handles. The signal is transmitted from this heart rate monitor to the treadmill, elyptical, or whatever, and shows up on the screne.
I wish the watch had a stopwatch and a light. No such luck.

Straps get yellowish, buttons cracked.
I received this watch as a Christmas present in 2005. I have been using it for the past 6 months (average 2x per week). I spotted this exact watch but with yellowish straps at an expo from Polar after I got my watch for only 2 weeks and was diligent about keeping it clean, but to no avail, it turned yellowish after about 2 months and now it just looks dirty and old, the face is still the original "ice blue". If you are thinking about this watch, buy the black one.

After I started using it, I wished I went with another model since this one doesn't store any previous data. I track all my runs and sometimes I forget to record before my next run and I lose all my previous data once I press "start". In addition, it doesn't have a stopwatch. Once you press stop, it thinks you're done with your workout instead of just a pause or break so you can't track your actual total workout time. I just let it run even when I am at stoplights or water break. If lap feature is important, go with another model. Another complaint about this watch is that there's no backlight. I have to wait till I run under a street light to see my data. The data sheet said it has a backlight but I can't manage to find it.

Today both the buttons cracked and fell off my watch. Now it's useless.

I still have the most basic model from Polar (bought in 2000 and it's discontinued) that only monitors my HR and that thing still works because there's no buttons to push. Polar makes good HR monitor and I would still buy another one from them. Just not this one.

Great watch
This is a great heart rate monitor watch for the money. I've been using Polar watches for quite some time and think this is the best I've owned. I recently tested/compared this watch (F4) to Polar's M61. The F4 provided more accurate numbers regarding my calories burned (which is the most important thing for me--heart rate and calories burned). I wear an Apex Body Bug that also monitors my calories. When compared to the Body Bug (which is extremely accurate) the F4 was on the money. The M61 only showed that I burned about 1/2 of what the F4 and the BodyBug showed. I also wear my F4 while swimming (which I cannot do with the BodyBug). So far, this was held up great to all conditions. I'm considering purchasing another as a back up or in case Polar for some unknown reason discontinues the watch. Great product!!!
