Nautilus Lifeline VHF - GPS Radio for Divers

Dive safety just changed forever with the introduction of this unit, a compact full featured GPS radio for divers that is depthrated to 425 fee/130 m. It is similar in size to a mobile phone but a bit thicker. You can use it as a full featured marine VHF radio or ask for help on CH16 from ANY boat around you within an 12 mile/18.5 km radius. Never worry about your dive boat finding you again. The diver location unit shows you your GPS position, VHF channel in use and battery life, it features chat channel and non-emergency functions as well as a DSC function allowing you to broadcast an alarm and your GPS position to every vessel in range that is equipped with a modern VHF marine radio. Lights will flash, horns will go off, everyone else's radio will autoswitch to channel 16 and your GPS coordinates and brief message will be displayed on their radios.

Distress Button:

Depress button for 3 seconds for DCS transmission of distress message. The unit will send GPS coordinates that will display on the other vessel's marine radios within 8 miles. Activate optional non-emergency group call with GPS coordinates and automatic channel switch for all Lifelines belonging to a specific dive boat or group.

Strobe Light:

We prefer to call this the diver position indicating light. Duel strobes will flash on the Nautilus Lifeline when in DISTRESS MODE which is especially useful after sunset.


The Nautilus Lifeline has the latest version Jupiter 3 GPS receiver displaying latitude and longitude on the LCD display.


Displays GPS position, signal lock, channel in use, battery remaining as well as volume, squelch, channel selection and GPS polling.

Boat Button:

Press this button to turn radio GPS on to Ch16, the universal hail and distress channel worldwide on EVERY marine radio. Use this button to select alternate channels 09, 14 or other pre-selected channels. The Nautilus Lifeline has imbedded software that prevents an inexperienced user from inadvertently locking the channel up.

Chat Button:

Pressing the Chat Button on the Nautilus Lifeline will turn the radio GPS on or switch to user selected marine VHF frequency. Use this button to change channels to any marine frequency. This is a fully functional marine VHF radio. Use both buttons together to adjust volume or squelch, select GPS polling or turn radio off.


The Nautilus Lifeline is waterproof to IP67 standards. Submersible to 10 feet (3 meters). The cap of your Lifeline can be opened on the surface (only) in any sea state allowing full use of all features.

USB Port:

Used for recharging the battery on the Nautilus Lifeline, downloading GPS log of dive sites onto Google map or interface for adjusting advanced settings.


1850 mAh lithium ion battery. The Nautilus Lifeline connects to any USB charger. 24 hours of battery life in DISTRESS mode.


VHF whip antenna. Waterproof to IP67 standards. Extend antenna for maximum range. Easy to stow when not in use. Range can be further extended by holding the Nautilus Lifeline above your head in the DISTRESS MODE.
