Divers are often surprised that we invented, designed and manufacture the Nautilus LifeLine Marine Rescue GPS. The shocking reality is that in the USA alone, someone dies on the water every 17 hours without being able to call for help. Just in the USA! Imagine what that number is worldwide. Our ambition has always been to save lives by helping as many divers as possible take safety into their own hands. To date, 37 divers have told us that the LifeLine saved their lives. We feel strongly that all our guests should own and carry a Nautilus Lifeline.
