PPS: FCC ID MH8APPS transmitter has one....
That said, as dive computers only have to receive the signal from a PPS transmitter, I doubt it will show up on a FCC report so we won't know if the Mk2i supports PPS until it is released (or someone gets hold of a manual).
I did go through a whole bunch of FCC reports for Garmin devices hoping to find the Mk2i but I couldn't find it. I found all the Fenix 6 range (which the Mk2 is meant to be based on) but nothing I could be sure was the Mk2 or Mk2i. What I was hoping for was the report would include the User Manual, as it did for the Garmin Transmitter and for the Mk1: FCC ID IPH-A3095
