The Series 500-12 Personal Locator Beacons are simple, compact, lightweight units which can be used either manually or automatically via ejection seat harness.

Fully compatible with the majority of search and rescue equipment including the COSPAS/SARSAT satellite based survivor location equipment. The PLB is a one-piece unit with the transmitter housed in a yellow pigmented or NATO green moulded thermoplastic case, which is designed such that the replaceable battery pack can be mounted within the overall package to form a smooth but non-slip hand portable unit.
