If you are the owner of a NERD Dive Computer from Shearwater Research, it has been announced yesterday on the Shearwater website that a bug has been found in the firmware for DiveCAN models. The bug affects the PPO2 decompression calculations.
Any DiveCAN users of NERD v09 should upgrade to v10 firmware.
Use Shearwater Desktop to update to the latest firmware (NERD v10).
Fischer NERD users are unaffected, but can update if desired. The Petrel and Predator models were never affected by this issue.
