Product Description

Product Description

Polar Chest Strap and Transmitters sold as a set. Features: Works only with CS600 and RS800

Amazon.com

The slim, light and waterproof T31 non-coded transmitter and belt set transmits accurate heart rate data to your compatible Polar heart rate monitor. It's fully water resistant, designed for all weather conditions and provides up to 2500 hours of training usage. In addition, it is compatible with most gym equipment. Note: The T31 non-coded transmitter does not prevent cross-talk/interference from other heart rate monitors and electrical devices. For coded heart rate transmission we recommend the T31 coded transmitter or the H1 heart rate sensor. Please refer to User Manual for more information.

Note: Getting started with your T31 transmitter is easy. For best results, thoroughly moisten the back electrode areas of the transmitter with water and adjust the strap length to fit snug, but comfortable. Check that the moist electrode areas are firmly against your skin and that the Polar logo is in the upright position. Tip: When you are finished with your workout, remove the transmitter, rinse with water and dry with a soft towel. Never store the transmitter wet, in a damp environment or in any kind of non-breathable material, such as a plastic bag or sports bag. Sweat and moisture may keep the electrodes wet and the heart rate sensor activated. This will shorten the battery life. Keep in a cool and dry place.

I had to buy a replacement transmitter for my Polar heart rate monitor because I must've not read the fine print that said dry off the transmitter when not using. Sweat moisture activates the transmitter that drains down the non-replaceable battery. I failed to dry the unit when I quit exercising, so the battery ran down quickly -- about 10x quicker than expected. Not too bright of me considering I have an advanced degree in engineering. So I'm telling you all now.

BTW, the new one works fine. No problem.

This unit worked well while it worked. It synched with both my Polar and Suunto receivers. But it didn't last. I bought this one in January and now it's November and it's dead. I checked that by using other transmitters and other receivers and this one is definitely dead. And yes, I wiped it off after each use. I used it once or twice per week for anywhere from 30 minutes to 3 hours. For forty bucks it really should last at least two years. Or they should just make the battery replaceable! What's the big deal? All the other HRM transmitters I've used have replaceable batteries. This is a bad design decision. I'll be using other brands from now on.
Update: A few months back I bought an Omron HR100 for someone else in my family. I tried the Omron transmitter belt with my Polar and Suunto receivers (uncoded) and it works great with both. Plus the Omron has an easily replaceable CR2032 battery. To cap it off the whole Omron system costs less than the replacement transmitter strap for the Polar. So that is the nail in the coffin for my relationship with Polar.

Ordered Polar T31 to replace a lost or stolen transmitter. It came in perfect condition in original packaging. Worked perfectly with my old wrist watch from the previous belt.

I am on my second transmitter-chest strap in three seasons. The first one lasted approximately 100 hours of wearing the belt and getting a heart rate, not sure if that is good or bad. I read somewhere to wipe down the transmitter after each use and store in a dry place, or the transmitter continues to try and produce a signal thereby using more battery. So, now after each use I wipe down the transmitter and make sure the strap, while still wet doesn't touch the back side. The strap has some antibacterial as there is no odor after repeated uses without washing (I tend to wash the strap after 2-3 uses). The strap synchs nicely with the crdio equipment (Precor) at my gym. I hope by following these tips I get more hours out of this transmitter than the first one.

I got this product to replace a very old one that showed symptoms of the battery finally dying. The replacement sensor works with my old Polar watch, and most importantly it works with my model WM100 Oregon Scientific SmartSync Heart Rate Logger with PC Download. The only downside is that it comes packaged with a size Medium elastic strap, which is useless to me because I still have to use a size Large at its maximum length. Good product that performs its function as designed.

Note: according to the manufacturer (Polar) the battery is theoretically not replaceable and therefore the whole sensor strap must be thrown away. I plan to dust of my old miniature electronic equipment repair skills to see what I can find in there, and if I am lucky I may be able to salvage the old one. An environmentally friendly improvement for Polar would be to redesign it with a replaceable battery. The logo sticker on the front eventually peels off anyway, so that would be a good place to start.

This product is designed with the battery sealed in. So essentially, their business strategy is to have you throw it away when the battery fades and buy a new one.
I bought this 2 years ago and am finding that it does not transmit a steady signal to the treadmill. It looks like the battery is dying. However, Polar says it cannot be replaced and the "discounted price" for a replacement strap is $30. That is ridiculously high - you can buy another brand including the watch, for that amount. I would instead recommend SportLine where the battery can be replaced.

Polar used to make decent products. You could change the batteries and keep using them for many years. Now you can't change the batteries. Was this design change for any good reason? No! They say it is because the unit is completely sealed. OK - they make watches that are completely sealed down to 30 meters of water pressure and you can change the batteries. Why can't Polar design a heart rate transmitter the same way? My guess is they make more money by getting you to purchase a new transmitter every single year.

This is ridiculous and just plain bad business. It's also detrimental to our environment as you now have to throw away a perfectly good transmitter in the trash that is made of plastic that could have had a long useful life had I been able to change the battery.

Polar also makes it almost impossible to change batteries on products that are designed to have replaceable batteries. I have a polar wrist watch. (I paid a decent amount of money for this) The battery died. I am pretty handy at replacing watch batteries and have all the proper tools. I carefully took the 4 screws out of the HRM watch back. As soon as I did the insides sprung open on me and lots of little parts went everywhere. There was a little spring on the top, and an aluminum cover that let loose. I tried for six hours to put it back together. I finally got it back the way it originally was and was able to replace the battery. It didn't work at all. I'm sure something didn't go back together properly after this event.

Why oh why would any Company design products so poorly? I can tell you why. They don't care! It's easier for them and more profitable to just make junk that you have to replace with new products every year or so.
