Tactix 7: Airplane Mode still recorded GPS data for Run activity??

I just did 2x one mile Run activities, but I accidentally had Airplane mode enabled on the watch for both.

I noticed this after the fact as I was walking to cool down, so I disabled airplane mode and then went to review the activity.

To my surprise, GPS data had been recorded, and the map showed my exact run path.

How is this possible?  Airplane mode is supposed to disable all wireless coms.  What am I missing??

  • GPS is receive only.  No wireless transmission. You can do the same with your phone ( or most phones).

    • "Airplane Mode: Select to enable or disable airplane mode to turn off all wireless communica­tions"
    • "Stealth Mode: Select to enable or disable stealth mode to turn off wireless communications and prevent the storage and sharing of your GPS position"

    "All communications" should mean transmission or reception.  If it doesn't mean this, then the definition should be updated to clarify.  Garmin has all this space to explain things... they go into great detail in some areas, and really skimp in others.

    Based on these descriptions, Stealth Mode would have prevented storage of the GPS location during my run but the watch still receives GPS location.

  • I'll consider this one answered (unintuitively).  I'll research my other question separately.  Thanks.
