Great watch and Heart rate monitor - works with my gym equipment,
This review is from: Polar F11 Heart Rate Monitor (Sports)THE BEST THING ABOUT THIS WATCH
all the Gym equipment at my gym has the POLAR logo on it. That means if you are wearing the strap (no watch required) you can set your heart rate limits on the treadmill or cross trainer etc and it adjusts the speed and difficulty to keep your heart rate in the preset limits. It's fantastic. If you use the watch as well, then you can go from machine to machine taking all the data from the complete workout. And if you hit your targets for a week a cup is displayed on the "time" screen (quite a motivator!).
REPLACING THE BATTERY
I own the Polar F11 (comes with strap). The Polar watch battery life is about 2 years with daily use of 1 hour a day (according to the manual). Admittedly this is much shorter than my Casio G-shock which promises a 10 year battery life. That's because the radio link between watch and strap uses more power than a watch that simply tells the time.
Another reviewer that complains that they couldn't get a replacement battery for the strap. Really they mustn't have tried too hard to get the battery out. A 2 pence coin can be used to unscrew the battery cover from the chest strap sensor. A standard CR2025 battery goes in, and the cover should be screwed back in place with the same 2 pence coin.
Replacing the battery on the watch is slightly more tricky. A precision screwdriver will be required to unscrew the back cover. Of course you need to be careful not to damage the rubber seal if you want the watch to continue to be waterproof. If in doubt take it to a jeweler. For that matter a jeweler would probably replace the battery in the chest strap too if you ask them. Anyway, changing batteries is explained in the manual.
READ THE MANUAL
This watch has a lot of features, and I must say you really do need to READ THE MANUAL to get the best out of it. The important thing is to manually set your heart rate limits to a suitable level for what you want to do. Generally there are three zones. Zone 1 is low exertion, i.e. I'm very unfit, recovering from an illness etc. Zone 2 is more suitable for Fat burn/light exercise, and Zone 3 is where you want to be if you are doing cardiovascular training, e.g. training for a marathon. The three zones are calculated based on your resting heart rate. Once you've set the zone you want to work in the watch will beep at you to tell you to speed up, or slow down. I've found the watch particularly useful for finding my pace when running as I have a tendency to either run too slowly, or too quick and burn out. By keeping me at the correct pace I can keep running much longer than if I went out running without my trusty watch.
The watch can also do periodic checks on your fitness and plot a graph. I generally do this every couple of months. All in all I'd say a great gadget for improving your fitness, tracking your progress and good for motivation.
