...It sent a couple nonemergency signals throughout the day, the last being about 3 p.m., Shuping said.
The beacon does not send out a signal that rescuers can track because it is based on satellite communications, not radio waves, he said....
Sounds like the
Spot Messenger, not a PLB.
Personal opinion, a map and compass properly applied would have made this "rescue" unnecessary. But if you are going to go with satellite based systems, start with a good GPS so you can stay found on your own. Don't unnecessarily burden the system because you got turned around/lost but are otherwise in good shape.
