Shearwater Firmware v87 for NERD 2 and Perdix AI, and v21 for Teric Is Now Available

Shearwater Firmware v87 is now available. This update is applicable to the NERD 2 and Perdix AI as they share a common firmware base. Firmware v21 is now available for the Teric.

Due to hardware differences, not all features are available on all models.

This release also includes new features, improvements and fixes. This v87 update is recommended for all users using NERD 2 and Perdix AI. And v21 for all users using the Teric.

Version 87 includes the following change:

  • This release is only for AI products (Perdix AI and NERD 2). This version addresses a minor bug where the Swift AI Tank Pressure Transmitter will occasionally send a false and unwarranted low battery warning. This change suppresses AI transmitter low battery warnings until four (4) have been received consecutively.

Version 21 includes the following change:

  • This version addresses a minor bug where the Swift AI Tank Pressure Transmitter will occasionally send a false and unwarranted low battery warning. This change suppresses AI transmitter low battery warnings until four (4) have been received consecutively.

    I have tried several times to update to 87 from 84 (brand new never dived Perdix AI) and it returns a failed result with CRC error. I’ve sent a message to Shearwood about this issue.

    Thank you and to Natalia. She replied quickly and I responded but then tried a reset and was able to update using the mobile app. You guys are fantastic as always and why I have two (soon to be three) models of your computers. 🙂

    I have a Teric running v21, with AI, but I have seen an odd (repeatable) behavior. If I turn on the tank and set the computer to dive (AI reports back tank pressure) then at 2m+ into the dive it says Dive Started in yellow and off you go all good. If I turn on the tank, but leave the computer in watch mode, then start the dive, I get Dive Started in yellow then I get a T1 critical battery warning also in yellow, then AI shows the T1 pressure correctly and the dive carries on as normal (I always have a manual SPG just incase).

    The T1 transmitter I am using is the grey model (not the new swift model)

    Thanks

    Mike

    Just bought a new Perdix Ai and downloaded a manual. In system setup and then mode Oc rec does not come up as an option instead it has Air, Nitrox and 3 gas NX as choice. Is that the alternative to Oc rec?

    Peter.

      Hi Peter, thank you for your comment. Air, Nitrox, and 3 gas NX are the “OC Rec” options. I apologize for the confusion.
      Best,
