The FastFind Crew1 AIS Man Overboard (MOB) device transmits an AIS MOB message with the user���s position and ID via AIS (Automatic Identification System) when activated. The transmission is then received by AIS equipped vessels within local radio range. The inbuilt GPS receiver transmits the user���s exact location, dramatically reducing the time taken to locate them. The FastFind Crew1 AIS MOB device also features a flashing white light to help rescuers pinpoint the user���s precise location in the water. The device can be carried in the supplied belt pouch but can also be fitted to lifejackets using the clip options as supplied. After the lifejacket is inflated, pull the activation cord downwards, releasing the red cap and deploying the antenna. Transmissions will then start shortly after, and the light will flash. This Crew1 device can be stored in a standby mode, ready to automatically activate on contact with water.
