Compass Error in Kestrel 4500 and 4600 Units
We've been receiving reports that the Kestrel 4500 and 4600 models are having an issue recording compass direction when the unit powers off. The issue started with firmware version 4.83 and has appeared in several updates since. We have resolved this issue with firmware version 4.89. If you have a Kestrel meter with firmware version 4.76 or higher and would like to upgrade your firmware to the latest version, please contact firstname.lastname@example.org to discuss your options.
Please note: Kestrel meters with firmware lower than 4.76 cannot be upgraded further due to their internal board, but should not be experiencing the issue.
