If you want to use CORE during high performance sports, you will get better and more quickly adapting results when pairing a heart rate monitor. If you buy one, make sure it works with ANT.

In the following I will explain how to pair a hear rate monitor to your CORE:

  1. Connect to your CORE.
  2. Click the heart rate icon.
  3. Initiate a scan
  4. To pair, choose the ANT ID of your heart rate monitor
  • Multiple heart rate sensors can be paired with a CORE device – it will use the first paired device it finds

You're all set up now!
All there is left to do is let CORE calculate your core body temperature.


It is good practice to clip the CORE to the same heart rate monitor strap. Secure the CORE to the HRM strap with the provided clips.
