In the event of a man overboard situation, the MLB will self activate 20 seconds after immersion into the water. The Sea Marshall beacon then transmits a signal which can be picked up by an onboard receiver to allow the crew to organize an immediate recovery of the MOB or if necessary to call upon the Search & Rescue teams to take over the operation.
The SAR organizations can then track the MLB signal on their own standard equipment. The MLB signal is set to 121.5 MHz which is the fixed, agreed international homing frequency. All SAR craft worldwide are outfitted with the correct equipment to monitor and track this signal.
The recommended Sea Marshall MLB (SMRS-LR or PLB8-LR) has a built-in electro luminescent light (night vision compatible) neoprene high bright antenna. This gives a visual reference to the search teams in addition to the transmitted signal.
