This is a NO RESERVE listing for ONE (I have EIGHT to sell) USED, Polar Electro IR Interface data transfer device in very good plus to excellent USED condition. This device is the interface between certain Polar heart rate monitor watches and the Polar Protrainer 5 software running on older WINDOWS computers. It allows the watches data to transfer to the Polar software app on the PC via infrared.

I don't know very much about these devices. After some research, I found that they are the interface between the watch  and the computer running Polar Pro Trainer 5 software. I've included some printed material and a copy of Pro Trainer 5--PC only and note this Polar interface is NOT for MACS. It works with several Polar watches including the CS600. RS800x,  and a lot of the other more sophisticated Polar watches made several years ago.

The  ProTrainer 5 app  works with Windows XP, Vista 7, 8,  and can be installed on Windows 10 but without full support. It is a 50MB application. The software on the disk may need to be updated--I've included only one version. As a Mac user I am not promising  that this IR device will work with your Polar watch and your Windows PC. for the price it's a steal and worth trying. Any additional research is your responsibility or you can try calling Polar in LI, NY.

Included with the IR interface that has a serial port  connection is the serial port to USB cable to allow connection to USB ports. I have not tested this device  since all my computers are Macs and this interface is PC Windows only.

Shipping is $5.00 via USPS First Class Mail with tracking. Good luck bidding.
