Kestrel Instruments Support & FAQs
Why do I keep losing my compass calibration on my Kestrel 5500/5700/2700 series Meter?
Typically this will happen if the Kestrel is placed near a magnet or magnetic source. Things such as the MagnetoSpeed Riflekuhl or other chamber chillers, electronic hearing protection, or maybe even magnetic buttons on your pocket. Any magnet can affect the compass calibration. Also storing the Kestrel in a metallic enclosure such as a gun safe can have an affect on the compass calibration.
