sMRT Personal Locator Beacon (PLB) Integrated with other MOB protective Equipments

Integrated LifeSaving PLBs (Personal Locator Beacons) with other Man Overboard protection equipment, including Life Jackets, Immersion Suits, and Dan Buoys.

Our PLB range is meticulously designed to comply with the latest international safety standards. It combines 121.5MHz, VHF DSC, and AIS GPS technologies into a single, compact, and robust unit, providing you and your crew with the highest chance of survival in the event of an MOB situation.

Critical for the Oil & Gas, Offshore, and Marine Industries.

Taking the Search out of Search and Rescue !


A Personal Locator Beacon (PLB) is a portable electronic transmitter designed for individuals to signal rescuers in the event of a life-threatening man overboard (MOB) situation requiring immediate rescue. Once activated, the PLB emits a distress signal on either the 406MHz frequency or the Local Area System, utilizing 121.5MHz, VHF DSC, and/or AIS technologies.

406MHz devices, like EPIRBs and ELTs, were traditionally standalone solutions for platforms such as aircraft, vessels, or platforms. However, they are now employed on individuals.

Activation Process

  • Signal Transmission: Once activated, the signal is transmitted at 406MHz.
  • Satellite Detection: The signal is detected by satellites in orbit.
  • Mission Control Centre (MCC): The signal is sent to the Mission Control Centre.
  • Decoding and Forwarding: At the MCC, the signal is decoded and forwarded to the nearest Rescue Coordination Centre (RCC).
  • Upon Verification (which can take up to 60 minutes):
  • Dispatch: The closest Search and Rescue forces are dispatched to the location.

MOB Alert

Local Area Systems

PLB’s operating on Local Area Systems use a combination of; 121.5MHz radio direction finding tone, VHF DSC distress alert (Mayday) on channels 70 & 16 and AIS GPS tracking, to alert the nearest vessel and provide updated location & tracking details to within +/- 1m.

Local Area Network

Types of PLBs that can be integrated to other MOB protection equipment such as Life Jackets, Immersion Suits, Dan Buoys.
