    I can’t seem to find where to set a depth alert/alarm in rec mode for the Teric. Please help! Thanks.

  2. Hi Shearwater

    When do you integrate stack time in the CC/OC mode on the Teric?

    Kind regards

      Hi Morten. As you’ve seen, the Teric does not have a stack timer option, and unfortunately, there isn’t information about this feature . I can confirm that your suggestion has been added to that feature request list. Thank you

    Is there any timeline for improving or adding some features for the free-dive modes? are where I can submit some suggestions – this is one of few free-dive capable computers rated deeper than 100m. There are some lacking features though

      Hi Shaun, while we don’t have a timeline for updates to the Freedive mode for the Teric, you can email us at with suggestions. We’d appreciate any features you suggest.

  4. Hi Team,

    I have had my Teric since 2020, the Iron man edition, never been on a dive yet thanks to the pandemic but i am scheduled to do so next week.
    I was trying to update from FW V18 to the latest V22 via the MS Cloud app but it always fails. Battery above 50%. It reaches about 55% and then the Teric sort of reboots and gives a tissue clear warning.

    Could you help please ?

      Hi Ajay, thank you for your comment. I’m sorry to hear you’re having this issue with updating the firmware for your 2020 Teric. Could you please let me know the serial number and current firmware version showing in Settings – General – System Info? Sometimes the firmware upgrade will go through, but may not appear to have done so. Once you check your current firmware version, if it’s showing as V22, then that’s great. If it is still not updating, could you try to update your Teric using the mobile Cloud app?

  5. I was using the latest apps on both Windows and Android.
    On windows it failed 4 times between 55% and 70%. The watch would reboot and give an error stating tissues would be cleared and then upgrade failed.
    But it went through in 1 go using the Mobile app.

    All good now 🙂 Thanks for your quick response !
