Nautilus Lifeline
Surface-signaling devices are considered a must-have safety item for many divers, and the Nautilus Lifeline takes that concept to a new, ingenious level. A combination GPS receiver and VHF marine radio, it gives divers the ability to speak with boats up to eight miles away. Plus, the system will broadcast GPS coordinates of the diver’s location to nearby vessels. A tough polycarbonate housing is rated to 425 feet and easily attaches to a BC’s D-ring. Battery life is 24 hours in emergency mode and, yes, there’s also a strobe.
