Condition is 9/10. Throwing in an old but working Polar FT4 for those who still like to wear a watch and monitor their heart rate. Chest strap is brand new as I used the monitor with an old one. Great for those who do not need the high commitment of an expensive activity tracker as it works really well for tracking heart rate and transmitting the information directly to your smartphone's fitness apps. Compatible with Polar Beat, Strava, Runkeeper, etc.
Uses low energy Bluetooth smart technology and coded 5 kHz transmission, providing ECG-accurate heart rate to any Bluetooth smart ready device and compatible Polar training computers
Provides live heart rate on your mobile training
