Personal Locator Beacon (PLB) · EPIRB / SART
Spot Gen4 Marine PLB is a emergency position-indicating radio beacon. It is normally installed in an approved accessible position, commonly near the bridge or externally in a float-free mounting depending on category. Its primary purpose is to transmit a distress alert and vessel identification for search-and-rescue response. Compared with routine ship radios, an EPIRB is a dedicated emergency beacon intended for distress alerting and autonomous deployment or manual activation. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
