The Mobilarm V100 VPIRB (VHF position indicating radio beacon) is a water-activated personal locator beacon that provides an automatic man overboard alert in water tracking, using the marine VHF radio band.

The V100 VPIRB personal locator beacon transmits a Mayday, man overboard alert and real-time coordinates of the person in the water within seconds of the fall overboard to all vessels in the range.

When the V100 VPIRB personal locator beacon detects the fall overboard, it automatically transmits the initial Mayday man overboard alert as a VHF DSC (Digital Selective Calling) distress alert. Once the device acquires a GPS lock, typically in 45 to 60 seconds, it transmits the man overboard alert again through DSC with the current latitude and longitude coordinates of the person in the water. It then broadcasts the message in a synthesised voice on channel 16, the marine radio emergency channel.

The DSC and voice messages are repeated at regular intervals during water tracking the casualty. The first known position is marked, frequently updated and tracked as they drift, providing rescuers with information about where to perform the search. Messages continue until the device is deactivated. The V100 VPIRB personal locator beacon’s battery supports transmission for a minimum of 12 hours and with a 1W transmitter, it has an alerting range of 2 to 5NM. It also features a high-intensity and SOLAS-compliant strobe light for visual homing.

The localised Mayday provides early warning of the occurrence of a man overboard incident. The V100 VPIRB water-activated personal locator beacon directly alerts the crew on board the closest vessel and a rescue team is then deployed immediately. This quick response improves the man overboard casualty’s chances of being found and found alive.
