Yes this is true, and when the chopper can't get in due to weather they know where to send the land crew.
Only plus side of the INReach/Zoleo type devices is they can ask you questions if you trigger the SOS function.

Think Garmin have had to pull their socks up (redo procedure) somewhat after Adam Greentree's Southern Alps debacle - basically the guy at the Garmin Helpcentre went to lunch for three hours and ignored Adam's SOS. Going to be interesting to see if the new Starlink/satellite cellphone coverage thingy actually cuts out the need for gps units/this type of tech.
Is that Garmin Helpcentre worker on a never ending lunch break now? That's pretty shocking.
That was before Garmin owned GEOS/IERCC (used to contract to them) - Now owned by Garmin and called Garmin response centre
FYI - Zoleo S.O.S goes to the Garmin response centre / IERCC
Garmin supports LANDSAR in NZ, and has a pretty good history as far as emergency and non emergency resolutions.

Full disclosure, I'm on the Garmin payroll.
