- Satellite-based alarm signal in an emergency -
PLB stands for Personal Locator Beacon. these devices are registered to the person, not the boat. Registration must be made in the country where you are resident.
AIS MOB / SART devices are best suited for use in coastal or inshore waters. These AIS MOB transmitters send an AIS emergency signal, which can be received by surrounding ships equipped with an AIS receiver. Because they use VHF frequencies, their range depends on the antenna height. We therefore recommend an AIS MOB transmitter in addition to your EPIRB.
