Nautilus Lifeline nexGen Marine Rescue GPS
AIS/DSC distress + position reporting — diver-tough to 130 m with fast GPS lock
The Nautilus Lifeline nexGen Marine GPS is a compact, diver-rated AIS/DSC beacon engineered to alert nearby vessels to your position at the surface. Unlike satellite messengers, the Nautilus Lifeline marine rescue gps communicates directly to AIS-equipped boats and your own vessel’s VHF (DSC), guiding responders straight to your GPS coordinates with minimal setup and no subscriptions. For divers, freedivers, and boaters who value clear, local maritime signaling, it’s a practical safeguard that fits any kit.
The Nautilus Marine Rescue GPS is built “diver tough”—depth-rated to 130 m/425 ft with a positive-buoyancy design and bright status/strobe indicators. nexGen electronics deliver quicker GPS acquisition, extended transmit time, and refined accuracy, while the optical-programming app simplifies MMSI setup for DSC where permitted. Carry it, forget it, and count on reliable AIS/DSC signaling when it matters.
