Amazon.com Product Description
Slim, lightweight, and completely waterproof, the Polar T31 non-coded transmitter and belt set accurately transmits your heart rate data to your Polar wrist-top computer. As a result, it's easy to monitor your heart rate during training runs. This version of the T31 is non-coded. If you're concerned about crosstalk from other electronic devices, Polar sells a coded version of the T31 as well. The transmitter belt--which works with all current Polar wrist-top computers except the CS600 and RS800--includes a sealed transmitter and elastic strap.

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.

Customer Reviews

Keep the unit dry when not using it.
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.

avoid. cannot replace battery. must buy a new strap every two years.
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 T31 Transmitter
Excellent delivery time and price from Amazon.com. I use the polar T31 transmitter when running, nice fit, good pulse response, belt usually wears out before the battery does.
