PLB = Personal Locator Beacon.
EPIRB = Emergency Position Indicating Radio Beacon.
They're functionally the same, using the same frequency and satellite network, but as above EPIRBs are intended for marine vessels.
EPIRBs are registered to a specific vessel, not just picked up and carried anonymously like a PLB for a hunter. And they're a legal requirement for commercial vessels I'm pretty sure.
