Garmin, with its mapshare link, allows anyone with that link to see your last position. If your InReach is set to default, it automatically sends your location every 10 minutes. Anyone with that mapshare link can also ping your location to get a current location.Don't you have to actually activate one of those? To clarify, the nature of my question is, 1) I know virtually nothing about these devices, and 2) if someone just disappeared, what device would make it easiest to track them? And always-on kind of thing, something that automatically pings every few minutes, etc.
