Polar WearLink Coded Transmitter (Medium/XX-Large, Black)

I have owned various polar heart monitors over the past decade. This particular band is a huge improvement. The wearlink transmitter detatches. This makes the band and the snaps that hold the transmitter much easier to clean. Also, the strap is one separate integrel unit that doesn't depend on the transmitter to complete the circuit. This makes it easier fot the strap to maintain contact with the skin, and leads to less corosion. All in all a superior product

This strap came with my M61 Polar monitor. It is very comfortable but sometimes difficult to disconnect. The transmitter began to give erratic readings after about a year. Sometimes, after about 30 minutes of exercise, the readings would settle (it had nothing to do with being wet). I regularly cleaned the strap, but decided to clean all contacts too. No help. I replaced the battery. Still no help. I feel this strap is way too expensive to give only one year of usage!

This is not even comparable with the strap I got when I bought the unit.
I use it for long hikes/climbs and sometimes I wear it for 12 hours; the old one was leaving me bruises, the Polar Wearlink is just perfect.

Big plus that you can change the battery.

Somebody was complaining it takes a long time before starting transmitting: you have to moisten it and it will work right away!

I purchased this item along with a Polar heart rate monitor. The combination enables me to maintain my heart rate within the desired range during cardio exercises. I have also observed that this transmitter works with many of the treadmills, bicycles and eliptical machines at the gym so I can monitor my heart rate on the readout panel of the machine without checking my wrist monitor.

Note: I understand from a friend that Polar USA will take back old/warn-out sensors and send you a new one for $25 or so. You might want to check into that if your looking for a replacement that is out of "Juice".

This replacement sensor is comfortable, but they sure are pricey! I personally never found the old plastic sensors un-comfortable, and if my girlfriend's dog hadn't eaten my old one out of spite, I wouldn't have bought a new one! -Recommended
