Shearwater Firmware V65 Software Release Notes

Shearwater Firmware v65 is now available. This update is applicable to the NERD 2, Petrel, Petrel 2, Perdix, and Perdix AI as they 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.

This update includes new features:

– Surface GF display has been added. It shows the gradient factor if you were to surface immediately. This is different from GF99, which shows your gradient factor at the current depth.

– Log sampling rate can be set to 2, 5, or 10 seconds (previously always 10 seconds).

– A “Deco Clear” up-counter option has been added.

This release also includes improvements and fixes. This update is recommended for all users using NERD 2, Petrel, Petrel 2, Perdix, and Perdix AI.
