A smart, intuitive training computer for runners and cross-training athletes, the Polar RS300X wrist heart rate monitor helps you to train at the right intensity with personal training zones. It's compatible with Polar's S1 foot pod and G1 GPS sensor (both separately available), enabling you to combine heart rate with speed and distance and truly make sense of your training. Committed runners will find the most value in the real-time pace and distance measurement of the S1 foot pod, while those who mix up their training regimen with cycling, inline skating, paddling, mountain biking or hiking will be best served with the speed and distance G1 GPS Sensor. It comes with the Polar WearLink+ 31 coded transmitter (with changeable battery).

The RS300X enables athletes to train at the right intensity and improve their performance through core metrics such as heart rate, speed, distance, pace, and calorie burn. Advanced features include Polar's exclusive OwnZone feature for individualized zone training by heart rate or pace, a fitness test, and auto lap splits, which display average heart rate, pace and distance per lap. Athletes can easily review up to 16 past workout files to check their progress and ensure they're staying on track with their fitness or training plan.

Features include:

  • Heart rate displayed as percentage of maximum heart rate, BPM, and average heart rate of total exercise
  • Tracks your latest 16 training sessions and your last 16 weeks of training
  • Visual and audible alarm in target zones: Informs you every time your heart rate and/or speed/pace exceeds the upper limit or falls below the lower limit of your target zone during a training session.
  • Polar OwnIndex Fitness Test calculates aerobic fitness (comparable to maximal oxygen uptake, VO2max) providing a reference to base training intensity and measure improvement.
  • Polar OwnCal: Shows your energy expenditure during one exercise session as well as your accumulated kilocalories during several exercise sessions. 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.
  • Time in Target Zone feature calculates the amount of total training time spent in your personal target zone. You can use this feature together with the Total Exercise Time to determine the effectiveness of your training program.
  • Number of laps - 99
  • Watch features: alarm with snooze, dual time zone, stopwatch
  • Compatible with Polar FlowLink (available separately)
  • Water resistant to 50 meters
  • Backlighting, display zoom
  • Event Countdown Timer: Keeps your motivation high by showing how many days are left before your next running event (e.g., Berlin 23 days).

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.

First, let me say that if you are interested in this heart rate monitor watch, it is probably because you will be using it mainly for the heart rate monitor. However, I would have liked to see a LITTLE more flexibility to use it as both a heart rate monitor AND a watch at the same time. Perhaps I haven't quite figured out how to easily switch between the clock and the actual timers, but it isn't a big deal if you don't mind that. It's certainly not a deal breaker by any means.

I haven't dug into the features too much at this point, but I have used it for over 30 sessions of weight lifting and running, and everything works really well. Some people have said there is interference at times, but I have yet to run into anything like that. I rinse it off after every workout, and even washed it in the washer once already. So far, the strap itself has worked pretty well, though I wish it would stay up a little more in the back. I have a wide back so I can't really blame the strap, and having something resembling suspenders would be a little absurd. Additionally, when using it for weight lifting, because of the necessary location of the strap, it can get in the way on barbell benchpress, barbell bent rows, or other exercises that might come in contact with your lower chest.

The watch is light, and I like the color because it is never hard to find. Sure, it would look a little goofy to wear out and about as a general purpose watch, but this thing wasn't made for that. The buttons are all very easy to press, though sometimes the main lap button at the bottom (red button) has not read my perceived button press. Perhaps this is user error on my part, as I can't be positive because generally it is right after I finish a sprint that I press it.

Well, it's been more than a month since I purchased this item and has worked well. The Polar wearlink is very confortable and can be adjusted to your chest size, plus you can change the battery yourself, not need to send it to polar factory. The instruction could be a little tricky but people learn more during practice than in theory. What I mean is, take your time to follow the booklet presing the different button and you will get everything in a very short time. For those who have experienced misreadout of your heart rates, it also happened to me. Sometimes I was doing easy cardio and my HRM would jump to 200 beats per minutes and I knew that was wrong, other times I would be doing really hard cardio and it would read zero 0. Well I read the trobleshooting portion of the instructions and it says that I must soak in water the wearlink and that I have to clean it everytime after use. I just run the wearlink under my faucet, dry with a towel a bit and that's it, it works perfect everytime, and I use it 5 times a week. I do not put it in the washing machine. Over all, it will help you understand if you are doing thisng right and not lacking and wating time during your cardio o exercise program.

I bought this when I started losing weight to get a more accurate measure of my calorie burn since the machines in the gym always seem to be inflated! It has helped me ensure that my cardio puts me in the right heartrate zone and tracks my calorie burn for a week which lets me know if I am behind or ahead for weight loss that week so I can alter my program along the way! I love it!

I could not figure out how to display calories in real time. Checked the manual, it only mentioned that you can view calories in summaries after the workout. So I figured that's not an option.
A review here pointed out to me I'm wrong.
Here's how you do it: start-settings-display-edit <display mode>.
Spelling it out in the manual would be nice (judging by my internet search I'm not the only one having trouble with this). But that's a nitpick.

Ok. Good looking and nice solution to have 3 rows for information. But the signal has been disappearing (losing contact between the watch and the sensor) exactly when i need it... I expected better quality for paying more than other similar devices. Also, navigation could be simpler (perhaps I'm the problem regarding it)...

I have been very disappointed with the heart rate monitor. During exercise i will notice no heart rate on my watch screen. Any advice or anyone else experiencing the same issue? I have cleaned strap and changed battery. Advice anyone?

It has very limited features . It doesn't show you the calories until you are done with the workout and it does not measure your speed or tell you how much you have ran unless you buy the foot pod ,, & that's an extra 100 $....

This was another gift for my daughter. She's a borderline healthnut and was just thrilled with this item. I know she will get plenty of use from this on her frequent trips to the gym.
