Personal Locator Beacon (PLB) · EPIRB / SART
The McMurdo PLB1 Max G is a personal locator beacon. It is normally installed carried by an individual or with personal survival equipment. It is designed for personal distress alerting when separated from the vessel or normal communications. The operating principle relies on manual activation of a registered satellite distress beacon, with position/homing functions where fitted. Compared with neighbouring models, the relevant differences are GNSS/homing features, activation method, battery and carrying arrangement; these must be confirmed from the installed documentation rather than inferred from the model designation alone. Service and survey attention should concentrate on registration, battery, self-test, casing/antenna and secure accessible carriage. For exact ratings, dimensions, tolerances, test limits and model-specific settings, refer to the manufacturer documentation for the exact figure.
What our service work and the manufacturer documentation say about keeping this model running.
Check battery/service expiry, approved self-test, casing, antenna, activation arrangement and identification/registration. Verify mounting, lanyard, pole or hydrostatic-release arrangement where applicable and ensure deployment is unobstructed. Do not generate a live distress transmission during routine inspection unless an authorized test procedure specifically requires it.
Internal repair is normally an authorized-service task. Carry only manufacturer-approved external mounting, lanyard, bracket, pole or hydrostatic-release parts where shipboard replacement is permitted, and schedule battery/service replacement before expiry.
