Thread: PLB and GPS or just an inReach?

I really don't understand why modern PLBs don't broadcast their position data on low power transmitter in the same way ships do with AIS.
Helicopters with suitable recievers could recieve the signal on a moving map and essentially fly to the user directly.

A lot of vessels now give their crews water activated AIS beacons so if they, god forbid, fall overboard a mark pops up on their nav equipment as soon as its recieved by onboard reciever so they can find said person quickly
