The Petrel, Petrel 2, and Perdix share a common firmware base. Due to hardware differences not all features are available on all models. The following changes apply to all models unless otherwise noted.

Listing of changes in Firmware v34



The ‘OC/CC’ mode has been renamed to...

Petrel Firmware V28

Fixed a bug in the Dive Planner where under some circumstances an ascent leg would incorrectly labeled as a descent leg and given zero time duration.


Petrel Firmware V27

Petrel firmware v27 is the first version to support the new hardware features of the Petrel 2, which are:
• Tilt compensated digital compass.
• Smart Ready Bluetooth (to add support for iOS devices).


Predator Firmware V59

V59 is recommended to all Predator users, as it addresses a flaw in the dive logging that can prevent dive logs from closing properly. This affected several of the previous versions, so all users are recommended to update.


Petrel Firmware V18 Released
