Test: Watch Polar RS800CX GPS



This watch is really perfect compared with my needs. Moreover I could not pay too expensive.
The GPS is more accurate with a high battery life, it’s easy to transfer and share data on Google Earth.
Lastly, the software Polar Pro Trainer 5 and the watch are very easy to use, efficient and it’s really beautiful. I put 5 stars.


Watch_Polar_RS-800-CX_GPSTo do my trip around the world, I would like a GPS tracer to record my tracks anywhere I’ll go.

Thanks to my relationship, I bought a second-hand Polar RS 800 CX_GPS pack as new with the CS speed sensor W.I.N.D.. So, I could save money (60% of price).

With this watch, I can record my tracks around the world and sell these in the future. The avantage of this product is the watch, the GPS and the body measurement have their own battery.

Also, I’ll practice lot of sports. It will allow to control my body measure and my physical condition over my trainings while suggesting a wide range of performance information.

This watch is really easy to use. In a half hour, you control all features. The GPS finds quickly the satellites (less than 1 minute) regardless there are big clouds, rain, or in the woods. Also it’s really accurate and you can record your position all 1, 2, 5, 15 or 60 seconds. After you will can see your track on Google Earth (.kml, .kmz) or a GPX software with your effort areas.

GPS has a high battery life (20 hours). This feature is important over long trail or when you can’t charge it.

The altimeter is more accurate too (+/- 1 meter) but don’t forget to configure it before start your training.

Lastly, Polar Pro trainer is more useful and easy to use. It records all informations and organizes these in a calendar with each week resume.

The watch has a big memory to record  data. With GPS and altimeter activate:

  • 1 second recording: 4h40 autonomy
  • 60 seconds recording: 270h50 autonomy

Also, the record rate increases when there is less than 30 minutes recording.

In one word, this watch and its accesories are perfect!
