Time Mark functionality

I am trying to determine how to sync my photos and GPS readings, and I want to better understand the exact functionality of the Time Mark pin. Does pulling the Time Mark pin down signal the Reach to simply record the time at which a picture was taken, or does it signal to the Reach to record the GPS at that exact moment in time?

If it simply records the time at which a picture was taken, how do I use that information along with the GPS logs to give my pictures a location?

Hello? Anyone out there? Do I need to provide more information in order to get a response?

Not my cup of tea but i`ll give it a shot.
Some links you might wanna look into

Hope this gets you rolling :slight_smile:
