How do I calibrate the compass on my Kestrel?

  • In order to properly calibrate the Kestrel compass, first, stand the unit upright. Turn the unit 360 degrees for 3 full rotations. For best results, turn 1 every 6-8 seconds. Note: Keep the unit away from any metal objects when calibrating and ensure that the battery shim is inserted. If you are getting magnetized battery error, rotate the batteries inside the unit.(If this persists, try using a different brand of batteries. Some batteries' magnetic signature is too high to calibrate the compass.
  • We also have a Calibration video that may help! See below
  • If you cannot get even one rotation to register, the issue may be firmware related and the NK support team can help! techsupport@nkhome.com
