Nautilus LifeLine Marine Rescue GPS

Nautilus LifeLine Marine Rescue GPS for Scuba Diving and Boating Emergencies

The Nautilus LifeLine Marine Rescue GPS is a compact, waterproof personal emergency signaling device designed to help scuba divers, boaters, and water sports enthusiasts communicate their location during emergencies. Using Automatic Identification System (AIS) and Digital Selective Calling (DSC) technology, this marine rescue GPS transmits a man-overboard distress alert with GPS coordinates to nearby AIS-equipped vessels and compatible marine radios within its communication range.

Designed for quick and simple emergency activation, the Nautilus LifeLine allows users to open the protective case, power on the device, remove the red distress cap, and press the emergency button. Its GPS positioning technology provides location accuracy of approximately 1 meter, while its AIS distress signal can reach equipped vessels up to 34 miles (55 km) away under suitable conditions. The device is positively buoyant, compact enough to fit in a BCD pocket, and depth-rated to 425 feet (130 meters) with the dive cap closed.

Stay Connected and Improve Your Marine Safety

Be better prepared for unexpected situations on the water with the Nautilus LifeLine Marine Rescue GPS. Combining accurate GPS positioning, AIS and DSC communication technology, positive buoyancy, and a compact waterproof housing, this personal emergency signaling device provides an additional way to communicate your location when assistance is needed. Keep it accessible during diving and boating activities for added emergency preparedness.

Important: The Nautilus LifeLine Marine Rescue GPS communicates through marine AIS and DSC radio systems and is not a satellite-based EPIRB or PLB. Successful reception depends on nearby vessels having compatible AIS or DSC equipment and being within radio range. DSC functionality requires compatible vessel MMSI programming and may be restricted or disabled depending on regional regulations. The 425-foot depth rating applies only when the dive cap is properly closed. Batteries are not included. Always follow the manufacturer's operating and maintenance instructions.
