Vancouver based Shearwater Research has announced they have released firmware updates for their dive computers.
Shearwater Petrel and Petrel 2
The Petrel Firmware V28 includes several changes for all Petrel Users. It also includes support for the new hardware features for the Petrel 2.
The Firmware V59 is recommended for all Predator users, because it addresses a flaw in the dive logging that can prevent dive logs from closing properly. This affected several of the previous versions, therefore it is recommend that all users update accordingly.
