Rated 5 out of 5 by Anonymous Does what it says and very well too.
I have this unit paired to my CS600x and have been very impressed by it. It is very easy to pair with the HRM and once paired it never needs any maintenance.
It gains a satelite fix within 30 seconds normally.
The antenae and reception is very good. Polar provides an arm band but I stick the unit in a sealed plastic bag in my uder saddle bag and it never misses a beat.
Charging is via a Micro usb means most phone charges will charge it, which take two hours tops, it can also be charged by plugingt into a PC. It then lasts for over 20hrs of use and the led on the unit gives a battery indicator too. The GPS Icon on the CS600x flashes when the GPS battery is low too, but it still held out for a couple of hours to be able to get me home.
A quality bit of kit and nice to review your route post ride.
The unit itself does not hold any data, all data is stored in the Heart Rate Monitor unit and downloaded as part of the normal exercise download process.
