Garmin Fenix 6 adds acclimation widget. dual HR broadcasting and more

Acclimation Widget on Fenix 6

With the exception of the FR945, all the Fenix 6 series today received a BETA update that you can now try at your own risk following the instructions in the links further below.

The heat acclimation capability has been available since launch (more details) and the feature makes adjustments like VO2max correction, although note your body (and the algorithms) will likely take 4 or more days until full acclimation. Also of interest is the addition of dual ANT+/BLE broadcasting of optical HR.

  • What’s new: What’s new here is the ability to add the acclimation info as a widget and, with the new widget glances, I reckon these are implemented now in a much-improved manner.
  • What’s new: Despite some limitations it’s now possible to broadcast your HR from the FEnix 6 over either Bluetooth SMART or ANT+. More info on

      1. The fact that link to Wikipedia is covered in words containing the letter z means it can be largely ignored on this UK site… 😂🙄
        Zee, my arse. 😜

    1. i thought it was
      acclimatisation for altitude
      acclimation for temperature
      mainly on the grounds that Garmin invented the word acclimation and then sneaked it onto the internet somehow.
      i then worked on the assumption that if i used each one alternately i would annoy everyone
      BTW: you could probably add a JHC to the FFS and still be correct.

      1. Your assumption is wrong. To annoy EVERYONE, you’d have to cycle between those two and acclimatation. 😀

        (Thank you Frank up above for the Wiki link, where I read that variant for the first time)

    1. nothing new. from earlier leaks the Instinct 2 could be addition of solar but otherwise very similar.

        1. find anywhere garmin_mobile.apk
        2. apktool d base.apk
        3. $ less /base/smali_classes4/i/a/a/a/a/o6/b.smali
