Polar T31 Coded Chest Transmitter and Elastic Strap

Bought to replace old stretched out one. Works very well.

I bought this "NEW" in June of 2016. In July 2018 it started not broadcasting my heart rate for about the first 20 minutes every workout until it gets warm and a little sweaty, then it starts working, slowly coming down from 220 indicated BPM or so to what my actual heart rate is. (my heart doesn't go 220-bpm) There are 25 spinning bikes in the room, it does the same thing ON ALL 25 BIKES, EVERY SINGLE BIKE SAME THING, so it is not the heart rate indicator on "THE BIKE"! I have used Polar HRMs since the 1990s maybe 1980s? Within the last 5 or 10 years or so the battery life has gotten shorter and shorter. Maybe mine sat on the shelf in some department store or in some bike shop for the first 5 or 10 years of its life before I bought it "NEW" from Amazon? I honestly don't know what to do. I have to buy another one because all the equipment i use at the health club (where i work) is Polar compatible. Maybe the non-coded one is cheaper and will last longer, we will see. This is a follow up, March 2019. I tried an experiment for the last month or two. I run the transmitter under water in the sink at the health club for a second or 2, just to make it wet. I put it on wet and i go into the spinning room and it works perfectly the second i turn on the heart rate indicator on the bike. All the way through the workout it works perfectly. SO if you have one that stopped working or works intermittently, run it under water and put it on to see if that makes it work. Maybe it is an indicator that the battery is getting low but this saved me from buying a new one at this time. Good luck!

I purchased this heart rate monitor transmitter to replace the one I lost. I use a Polar F6 (A few years older model) and it works flawlessly with it. I'm 6'2" with a 42" chest and this strap fits comfortably with little adjusting. When I'm working out I don't feel it and the slender form factor doesn't show through my clothes when I'm exercising, but I suppose it could if you wore tighter fitting clothing such as those Under Armor shirts or a bicycling shirt. The transmitter communicates well with the Precor machines at my gym, however I have noticed that it reads about 1 BPM off between my watch & the exercise machine. It's not that big of a deal, it's just something to point out. Using the Polar brand, you're introduced to the OwnZone, which is a custom tailored heart rate range for the day. It's really a great tool to use. I now focus on getting my heartrate into that range as quick as I can and keep it there throughout my workout. Make sure you read the instructions and wet the transmitter areas before you work out. This will help transmitting and if the exercise machine you're on isn't reading properly, I found that moving the band down a 0.5" to 1" will make it start reading normally. I've heard the big negative to this device is that the battery must be changed by the factory and it's less expensive to replace the entire product. With an approximate 1-3 year battery life, I'll probably purchase another rather than send it in and wait for the turn around.

I purchased this telemetry strap to use while working out at the gym. Almost all the cardio machines at my gym have Polar receivers and can display my heart rate from this transmitter without having to hold on to the physical sensors. This may not seem like a big win, but it's much more comfortable to walk on a treadmill or use an elliptical machine without having to hold on to heart rate sensors. Using the strap is easy: you just wrap it around your chest, connect the loose end of the strap to the sensor and moisten the contacts. There is no on/off button so you don't have to worry about anything except for putting it on. It is fairly comfortable to wear, and I don't really notice when it is on. The whole thing is made out of plastic and the strap is elastic. The build quality is excellent and it is completely waterproof. The strap is 'coded' which means that you don't have to worry about interference from other people wearing straps around the gym. This works with the polar wrist-watches, but I have found that the 'coding' doesn't work with the Life Fitness treadmills/elliptical machines or the Precor elliptical machines at my gym. Your mileage may vary, but if the person next to me on the machine is also wearing a telemetry strap, the machine will get confused and vary wildly in its reading. Sometimes it will display my heart rate, and others it will display the person next to me. This is more a problem of the proximity of the machines. If the other person is one machine away, there is no problem with interference. I haven't found this to be a big deal, if I need to I just move one machine over. Pros: + Fully waterproof + Excellent build quality + Comfortable + Accurate Cons: - Interference with other transmitters nearby in gym (this is a problem with the receiver on the equipment, not the strap). Bottom Line: Excellent strap to use with a watch. If you are using in a gym with a receiver on a machine, be prepared to deal with some interference if there is another transmitter within 5-10 feet.

It quit working after a few months

I go to the gym and am always frustrated when I can’t get a correct heartrate reading on any of the cardio equipment. Especially when running, it is almost impossible to hold the heart rate handles to get an accurate reading. I am 52 and have lost 30 pounds in 5 months, but I had reached a plateau. I finally realized that my heart rate was much too high to burn fat, and I researched which type of telemetry strap would work with the cardio machines. This strap was recommended by the manufacturer of the equipment, and since I started using it about 4 weeks ago, I lost an additional 10 pounds by keeping my heart rate in my target zone (which was MUCH lower than what I thought I needed in order to burn fat). As soon as I get on the machine, I can see my heart rate on the machine’s display, and it never has a problem picking up the information from the strap. The strap is comfortable, easy to adjust and put on, and there is no programming on syncing required. I never go to the gym without it, and I can easily make sure that my heart rate returns to normal during my cool down phase before I get off of the machine.

I have purchased the Polar T31Coded Transmitter and Belt Set from Amazon as a replacement for my old transmitter and belt. Before bying this set, I have considered replacing just the battery itself but the cost and headache for doing it were both not worth it. Also, there was nothing even close in the price range at the Dick's Sporting Goods that I could find as these parts are not being sold by the stores. I have to say that I am NOT using the original wrist watch that came with this set due to the fact that all of the Precor aerobic machines in our gym support this set by directly reading the heart rate from the belt transmitter and displaying it on the console. It is a much better and more convinient option for me not to have to check the wrist watch and play with it so the compatibility with other exercise equipment is something I care about a lot. This product is very reliable as it took over 12 years for a battery to wear-out before I had to replace it. I am strongly recommending this product based on its longevity, durability, quality, compatibility with other equipment, and price affortibility.

I didn’t fully read the instructions. This will not pair to the app on your phone. It will only transmit to a Polar watch. I returned to buy the correct model that will pair to app on phone.

La fascia precedente è durata più di 5 anni e anzichè sostituirla con un'altra fascia, con poca differenza di prezzo rispetto alla sola fascia, ho acquistato un nuovo cardiofrequenzimentro Polar, comprensivo di fascia, ma altro modello più recente e con più funzioni. Purtroppo, non so se fosse difettoso, rilevava la frequenza cardiaca ma dopo qualche minuto perdeva il battito e diceva di riposizionare la fascia. insomma, durante l'allenamento ero sempre a spostare la fascia, ma la frequenza veniva continuamente persa. Ho deciso di restituirlo e Amazon mi rimborsato immediatamente il prezzo pagato e successivamente mi ha inviato il corriere a ritirare il reso. Un servizio incredibile. In nessun negozio tradizionale si può avere un servizio simile. A quel punto ho ordinato questa fascia, come quella esaurita, per il mio cardiofrequenzimetro e funziona senza nessun tipo di problema. La indosso, accendo il cardio e mi alleno. Per tutta la durata dell'allenamento non perde un battito. La uso anche con il mio stepper Tecnogym, lo accendo e aggancia immediatamente il segnale: favoloso. Avevo solo un dubbio, che la fascia codificata potesse essere solo utilizzata con il suo cardiofrequenzimetro e non con attrezzi cardio, invece funziona perfettamente anche con le comuni macchine da palestra, basta non collegarla al cardiofrequenzimetro da polso. Insomma: pienamente soddisfatto

Funcional con caminadoras

POLARの機器に使用してます バッテリー交換は出来ませんが 機器との相性も良いです。

Uma droga Não funciona. Além de tudo uma dificuldade para tentar devolver

Der Gurt funktioniert einwandfrei und verbindet sich mit den Geräten im Fitness-Studio.
