H10 Heart Rate Sensor – Black – ANT+ & Bluetooth, ECG/EKG Accuracy, HRV Tracking, Waterproof, Machine-Washable Strap, Comfortable Fit, Replaceable Battery, Sports & Gym Compatible M-XXL 75-115cm

A fantastic heart rate sensor! I recently had a heart attack and was looking for something to monitor my heart during recovery and walks. Firstly I tried a Fitbit Charge 6 and was extremely disappointed at the lack of functionality with regards to a dedicated HR screen. It's just an overpriced fancy watch with some exercise stuff. So I took a peek at Polar, after a recommendation from a friend (who is in the Navy and uses these for fitness tests). They're far cheaper than a Fitbit, easy to use, have an easy to use app with GPS to track your routes and it saves all the data collected onto your phone to review as time goes on. I've used this a couple of times and it feels okay, doesn't come off while walking, is fairly comfortable and simple to put on/take off. If you're looking for a more HR and ECG based device, definitely choose this rather than a Fitbit!

So the H10 is very good heart rate monitor. Works well during exercise, stretching, running, hiking and martial arts - generally fits nicely and snugly on the chest during all physical activity - that you can forget that it is on. Connection with smartphone during recording exercise - it is very well, it can loose connection if you are using other app requiring the GPS access, then you need to refresh the app (polar beat - just refresh) as other wise it will stop working due to some issues with multitasking and sharing processing at the smart phone. Alto it is work well if you use option of the recording the exercise with the H10 heart sensor and download after you finish. IT works well with watch, no problem at all, no loosing signal, very accurate. The software and app is extremely good and user friendly, providing very good analytical data, and information which you need in nice easy to read format. Compared to the Sunnto, and Garmin software - the way how the data is collected and presented was winner for me to choose the Polar chest heart rate H10. As did not have chance to test it in the water as the swimming - can not comment on that. It works well at the rain and storm weather when you are completely soaked tho :) The strap itself is good size with length regulation. Is has some silicon bumps which helps to keep it nice and comfortable in one place, so it not move around during the high activity exercises. It is very easy to change battery - which make this product last very long. Tested it connected to the watch and smartphone at the same time as it support simultaneously twin connection into the two devices at the same time!!! as well as it can work with one device, and on its own, no need to take phone with you - if you click in the app start recording with the sensor rather life recording with the app, then you can just go with the sensor and when you finish just download the information to the phone. So yes I would recommend it.

****Review update**** I originally gave this product 3 stars - I was having mixed results with it. I assumed that this HRM was not able to maintain and record bluetooth and 5Ghz "gymlink" connections at the same time. I would switch the app on (polar or wazoo) in my gym. The PRECOR gym kit would show my HR, but when I checked the app, it showed significant drop outs. I RESOLVED this. It transpired that this was a power management issue on my phone, if I was using Spotify/Netflix at the same time, my phone was not running HR tracker apps in the background. My phone is a Huawei P30 Pro - I went to settings>Battery>App Launch and turned off "Manage Automatically" for each fitness app. Now it appears to operate flawlessly. Both for CV and resistance workout. Now - I give this 5 STARS The Polar H10 features a suite of connectivity options as follows; - ANT+ - which is a Garmin product, and I've yet to find a use for it. I own no compatible equipment. - Bluetooth - great - can support 2 devices simultaneously. - 5ghz "gymlink" - which can connect to some gym equipment eg. Precor In the Polar app you can switch each of these off - I guess this would save power. I cant comment on battery life - not used it for long enough but polar app shows it as "FULL" after 8-10 hours training. The strap is not one of the generic ones, has a plastic clip to connect it together, which I hope will hold up. The cheaper ones have a metal clip. The Polar app is more than sufficient for me - provides a number of profiles for different activities. And a good HR readout is provided at the end, and you can easily see the HR zones as you train. Ive also tried it with Strava, MapMyRun, and Wazoo. All with good results. I cant comment on water resistance - others have commented on this, but I do not swim with this on.

I'm a cardiac arrest survivor, and, two years on from the event I need to get moving again. But safely! I used to cycle a lot and have realised that the flat canal paths near me offer a good gentle environment to return to cycling. However I still need to know that I am in the safe zone for my heart. The Polar H10 came with some great reviews, particularly for accuracy. I didn't want to spend a lot of money on a fitness watch, I wear a classic! Having bought the H10 I downloaded the (free) Polar Beat app to my Android and signed up to the (free) Polar Flow on my Mac. The H10 connects well to the app via Bluetooth so I start the app, cycle, and check the results when home, they are automatically shared to the Polar Flow too so I can see it on my Mac. I use accurate GPS on the phone and the readouts let me run through my journey on a map. It's early days yet but I'm really impressed. The GPS dropped out on one trip but the heart monitor kept reading. I did accidentally delete one of my sessions of Polar Beat, it seems there is no way to recover it which is annoying. However the level of analysis and understanding that can be gleaned from this device is fantastic and on this brief acquaintance I would recommend it highly. We are visiting Paris this week and I typically walk a lot in cities so I will try wearing it for a walk or two.

Very accurate and comfortable

I bought this, plus the strap in July 2022. Initially it worked very well but had the odd data hiccup where the heart rate would drop from say 144 down to 135 for about 30 seconds then restore itself. I thought that was acceptable, not ideal but acceptable. All I’m trying to do is keep an eye on my heart rate and not over do it but also record the average heart rate over the session on the Polar Beat App so I can compare sessions fairly accurately. Recently, say over the past 12 weeks or so, the data drop out has gradually become so stupidly severe the transmitter is totally useless. The problem I think is that a decent quality battery now only lasts about 4-5 30 minute sessions if that. The voltage of a new battery is usually say 3.31 Volts. Once the HRM has been worn a few times, as soon as the voltage drops to about 3.00 Volts, the data recording becomes totally unreliable. I’ve just tried some Duracell Procell batteries and they are producing exactly the same results as the Duracell batteries so I really don’t think there is any issue with the battery. I should also mention that there is plenty of saliva used on the strap to help conductivity. At the moment, I feel it would be far more accurate simply guessing your heart rate. Also, irritatingly, the Beat App sometimes produces a message saying it can’t connect to the monitor because another App is using it. Well, it isn’t and I can’t get rid of the message without unpairing and repairing. That’s a pain in the arse if you’re out and about doing a run and you want to split it and restart. Last night was the final straw because I was using a new battery, without a tee shirt on and the transmitter was about 15 – 18 inches from my phone and the recording was utter rubbish – see picture. Additionally, the cross trainer should pick up the signal and display accordingly but it never displayed at all for the whole session. I’m going to try to contact Polar customer services to try and resolve this and if the situation improves drastically, I’ll amend the review. If it doesn’t, I’ll ask Amazon if I can review with zero stars, add some nice comments about the Polar Support and start investigating Garmin HRMs.

The item arrived in a nice efficient package and was easily unpacked. Adjusting the strap is very straightforward and, once suitably modified, the strap is comfortable to wear after the initial shock of the cool pads passes. I found pairing the device to both the polar apps and the QZ app I use for my spin bike very straightforward and have had no issues with the device being automatically picked up on subsequent workouts. I bought this primarily for the reliability of the monitoring and open nature of conenction (i.e. being able to easily pair it to third party apps/devices) and I'm happy this has lived up to the promise on both counts. The monitoring element is more accurate than the optical monitor I had in my Pixel watch so I'm happy that my workouts are now being more accurately tracked and heart zone based training is more easily tracked now. The Polar apps themselves seem a bit rudimentary but, as noted, you don't have to use them for anything meaningful besides adjusting device settings and applying updates. That's going to be such an infrequent activity that I'm not counting it against the device. At the sale price of ~£60 this is an easy recommendation to anyone needing an open, accurate HR monitor.

Excellent price and glad I went for this model. Easy to use and took my training to another level.

Comme d’habitude chez ce fabriquant finlandais, c’est du haut de gamme et vraiment à la pointe. Le cardio très bien adapté a une multitude de sport. Dans mon cas je l’utilise pour le running et le vélo (VTC surtout). La sangle pectorale est bien conçue et très confortable, elle se fait totalement oublier sitôt mise et elle ne glisse pas lors des entrainements, ce qui est très agréable. Je l’utilise connecté à mon smartphone mais le H10 peut enregistrer sans aucun appareil externe jusqu’à 30 heures d’informations de fréquence cardiaque avec une précision d’une seconde. Note : ces informations sont considérées comme une seule séance d’entrainement, il faut donc synchroniser les données via l’application Power Flow avant de recommencer un entrainement. Un autre point fort du H10 est la possibilité de se connecter via Bluetooth au smartphone et via ANT+ (protocole d’interopérabilité entre matériel) pour interagir avec la plupart des appareil de fitness (vélos, rameurs, tapis de course…) et également des montres de marques autre que Polar. Note : les connections peuvent être simultanées (i.e. connections au smartphone et un appareil de fitness). Si vous possédez une GoPro vous pourrez même superposer votre fréquence cardiaque synchronisée avec la vidéo ! Il semble peu énergivore, après un mois d’utilisation Polar Beat indique que la pile est toujours à pleine capacité ; il est donné pour 400 heures d’entrainement. La pile (CR2025) se change facilement. La sangle capte les battements cardiaques à l’aide de capteurs enregistrant les signaux électriques ce qui est très précis. Coté utilisation, j’utilise Polar Beat. L’application est, en ce qui me concerne, vraiment bien conçue, très intuitive et ergonomique. Sélection de l’activité, « start » … point final. Ensuite l’application affiche les données de l’entrainement (durée, distance, fréquence cardiaque avec max et moyenne, Kcal consommés, % de graisse consommé…) et la trace GPS et carte du parcours. Toutes les séances sont historisées pour consultation ultérieure du parcours avec toutes les données. Elle dispose d’un mode permettant de calculer votre VO2 max, de 2 modes de coaching etc… tout est prévu pour optimiser votre potentiel d’entrainement. En bref, le Polar H10+ est le compagnon idéal pour tous les sportifs réguliers…

Sensore preciso e affidabile. Il Polar H10 si collega subito allo smartphone e le misurazioni della frequenza cardiaca sono molto più accurate rispetto ai sensori da polso. Fascia comoda anche durante utilizzi lunghi e ottima qualità costruttiva. Perfetto per allenamento, HRV e monitoraggio dettagliato. Consigliato.

Calidad y funcionamiento de lo mejor en el mercado si necesitas un medidor de F.C. he usado el H7 mucho tiempo y en comparación con el H10 la concectividad y precision son impresionantes y mas por la funcion de grabar la sesión. Sin necesidad de tener el teléfono cerca.

Perfect, beste op de markt

Authentic product, works brilliantly
