Shearwater Firmware v65 for NERD 2, Petrel, Petrel 2, Perdix, and Perdix AI Is Now Available

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.

    Has Shearwater ever considered offering a CCR feature whereby users can see how much dive time is remaining based on their accumulated deco obligation, bailout carried and RMV?

      Thank you for the suggestion, Hugh. I’ve logged it as a feature request. Please keep in mind that this does not constitute a promise to implement this feature.

    Another way to do that could be a “bailout TTS” display that can be displayed in CC mode without switching to BO mode.

    After updating my Perdix AI in the log, all the Start and End pressures as well as the Avg SAC in each logged dive show N/A.

    Where is all this data gone and how can I get it back?

    TIA,
    Peter

      Hi, Peter. Sorry to hear you are having this problem.
      The data is still in your Perdix AI. It is not deleted. A bug is preventing it from showing. We are aware of the issue and have it as a high priority item to fix. I cannot currently give any timelines on the next Firmware release. I want to stress however, it is a priority. In the meantime, you can use the Shearwater Cloud app on your phone to check the tank pressures for the dive. Regards.

    Thank you all for the fantastic feature additions. Surfacing GF is very practical. I hate to look a gift horse in the mouth, but could not see another place to propose other enhancements. Is a numeric ascent rate indicator something that has been considered?

      Thank you for the kind words, Dean. We have a numeric ascent rate indicator in the Teric. We will take it into consideration for the Perdix/Petrel/NERD 2 interface, but we cannot promise implementation of it at this moment. Cheers.

    Since the last firmware update my Perdix clock gained 20 minutes, I saw this today when comparing my dive entry time yesterday to the entry time on my wife’s Suunto, never had this problem before.
