The Nautilus Lifeline... the piece of gear you hope you never need, but glad you have it if you ever do! In an emergency, simply open the cap, push the button. Your GPS position is accurate to 1.5 meters and a man overboard distress message will be broadcast to all AIS equipped ships up to 34 miles away as a special DSC message to the marine radio on your own vessel. All modern commercial ships and most yachts are equipped with AIS and DSC allowing universal worldwide use of the all new Nautilus Marine Rescue GPS. Each GPS is programmed at our factory with an MID number allowing automatic AIS functionality as soon as your unit is powered up. Your ship’s MMSI must be loaded with the simple to use built-in optical sensor to activate DSC functionality.

In the unlikely event that you’re at the surface and need to get the attention of someone on shore or on a boat, you’ll be glad you have a surface signaling device. Signaling devices are important safety equipment that help scuba divers be seen and heard if they need assistance. The recommendation is to always carry at least two devices – one audible and one visual.
