H9 Heart Rate Sensor

Accurate. Best in class chest heart rate sensor. More affordable than H10 which has a bit more features. When it comes to accurate HR measurement it is as good as H10!

Gives out accurate value. And has a phlethora of workout options. Can track almost everything with this. It's comfortable to wear and I haven't faced any problem whatsoever.

Good Product

Good Product but it is not rechargeable it runs o battery

Wrost… I have used 5–6 Polar heart rate monitors till now, and sadly almost every one stopped working properly after 3–4 months. ( i use for daily mma & CrossFit training )Unfortunately, we don’t really have many other brand options available, so we still have to use them. But honestly, the performance and durability of these heart rate monitors have been very disappointing.

This is a very good product. The heart rate sensed is accurate compared to other wrist worn sensors. Th Polar Flow application is also very good providing real time update of heart rate and gps track.

I did a TMT test in a hospital wearing this. It is almost near reading and sometimes accurate reading of the hospital equipment where multiple sensors will be sticked near to the heart

I have been using this since 5 months. It's actually a good product. Will do the job well. Stap is good. App is good. And battery is also good as of now. Worth every penny

Sehr genaue Messwerte und eine zuverlässige Verbindung mit verschiedenen Apps und Geräten. Die Einrichtung ist unkompliziert und der Brustgurt sitzt angenehm, auch bei längeren Trainingseinheiten. Lange Batterielaufzeit sowie problemlose Kompatibilität mit Bluetooth und ANT+.

Does it’s job. Simple setup and straightforward to use . Have been using for more than a month and has worked flawlessly. Mainly used while cycling and a few times for brisk walks. Heart rate readings are consistent without drop outs

Bardzo dokładny i szybki pomiar, wiarygodny odczyt. W kwestii liczników/komputerków kolarskich polecam zastosować protokół transmisji ANT+ a nie bluetooth by uniknąć problemów ze zrywaniem połączenia (większość liczników przy parowaniu wyświetli urządzenie Polar pod ANT plus jako ciąg cyfr zaś w przypadku bluetooth będzie to najczęściej nazwa+cyfry)

The strap sucks. If you have no lats, maybe it won't slide down your body as you run. But for those of us with big lats, you have to modify this thing. You can either modify the strap, or buy the $40 Polar Pro chest strap (you’ll have to replace any strap you get probably every 6-12 months so keep that in mind). I haven't tried the outrageously-priced Polar Pro but it's the only one on the market that has grips all the way around the strap, not just in the front. The chest strap can be easily modified as follows: Buy one of the "zig zag silicone grip wave bands" you can find online, and sew it (or use fabric glue or something) to the inside of your Polar chest strap and it actually stays in place while running! Just make sure you get the strap customized to your underchest first, and give yourself some space for the inevitable long-term loosening of the strap (you might need to tighten it gradually over time). Without the extra grip, you have to find the perfect balance through much trial and error between too tight and too loose. Too tight, and it creates a little cavity where the electrodes are between the strap and your chest (so it gives you terrible readings, if any). Too loose, and it falls down to your waist. I also found that using a small dab of electrode gel on each of the two electrodes on the back side of the chest strap (enough to cover just the two circles on the strap where the strap touches your chest) makes a huge difference in getting a consistent, accurate, read. Don't use water, it just doesn't work nearly as well. I love the Polar Beat app it comes with! It was the best free app I could find for Android for a heart rate monitor. I'm sure there are probably better paid ones out there but I didn't try any of them so can't attest. The Polar Beat app gives you a graph at the end of your workout that shows your heart rate over time, and tells you how many minutes and seconds you spent in each of the 5 heart rate zones (50%-60% of max heart rate = zone 1; 90-100% = zone 5). It has certain modes that track your GPS location for accurate maps of your runs/rides and the app will tell you every mile when running how long your mile took, your pace, and average heart rate. I've never used it for a bike ride. It also tracks calories very well and whenever it doesn't get an accurate read, it does a pretty good job "guessing" (better than the old Polar Watch I have). If I start my workout on the Polar app first, THEN start the workout on my Polar watch, it will let me use both to track my workouts which is great. That way I can leave my phone in my gym bag while running around the track, and use the watch instead to track % of max heart rate. It's also nice when using my phone for anything else while I'm doing a HIIT circuit or on the exercise bike, that way I can just look at my watch to see my stats. I don't have a smart watch so can't comment on how it works with that. I think you might need to get the latest and greatest to pair it to two or more smart devices at once. But this one works perfectly for one smart device and one dumb device.

Facile d'utilisation mais j'ai mise 1 fois et la pile était morte
