Peace of Mind


Have not needed to use this, but it is reassuring to know that it will be there if needed.

The new Nautilus Life-Line Marine Rescue GPS is easy to use! Open the latch, press blue button to turn on, remove the red help cap, and hold red H" elp button for 5 seconds, you're transmitting, that simple! The all new Nautilus Life-Line is less than half the size of their original radio and is incredibly simple to use. No special or dedicated base units required. No registration, subscriptions or service fees required.Your Nautilus Life-Line floats! It is waterproof in all sea conditions. Life-Line GPS is waterproof. It is depth rated to 425' (130 meters) with cap closed. Long battery life, just keep the O-ring clean and forget about it for the next 5 years! GPS is powered by two CR123 3V lithium batteries. These batteries are not included with the device and are user-replaceable.

Accurate positioning, your GPS position accurate to 5' (1.5 meters) and a man overboard distress message will be broadcast to all AIS equipped ships up to 34 miles (55 km) away as well 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 Life-Line. Each Life-Line GPS is programmed at 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.

The Nautilus Life-Line Marine Rescue GPS has a transmit power of 1 amp, with an AIS frequency of 161.975 MHz and 162.052 MHz, and a DSC transmit power of 0.5 watt with DSC frequency of 156.525 MHz. The unit messages individual distress and relay distress alerts. The Nautilus Life-Line GPS has a durable and waterproof polycarbonate housing with 316L stainless steel hardware.

Peace of Mind


Have not needed to use this, but it is reassuring to know that it will be there if needed.


Still thinking if it was a good choice...!

By Xavier R.

from Pto. Ayora, Galapagos, EC

I have my doubts, one buttom came off right after I opened the case, and that is not a good begining. Up to now I have carried it once to the sea. I added some glue so the yellow buttom doesn't come off in the water. I should have stayed with the other unit that has a radio incorporated. I have used the other unit onboard a liveaboard that I worked in at Galapagos.


Terrible “upgraded”.

By Globulen

from Bethesda, MD, US

I returned the previous version that was an actual two way radio for this. I wish I hadn’t. It’s smaller, yes, but harder to use, no screen, no radio, a ridiculous antenna that needs to be wound back with a piece of plastic, no rechargeable batteries, etc etc. It’s a total downgrade from the previous larger radio unit. Don’t buy.


Questions & Answers

Questions about this item:

Shopper  Why Did You Choose This?
APRIL K  The Nautilus Life-Line marine radio and GPS is no longer made. Already have this one but wanted one for my wife. Never had to use and hope we never have to use but cheap "insurance" having it just in case.
Dan C  Is the signal able to reach helicopters when in the mountain?
OSCAR L  Sorry. I can not respond at this point. Even though I bought it, I don´t still use it because I live far from the sea and I haven't get opportunity to go diving. Possibly I´ll do it the last months of this year
KEVIN H  This unit is a marine band signal only. It does not have any radio in it. You should go to the Nautilus website.
L R  Possibly. However, signal is still "line of sight" and aircraft would have to be equipped with the proper radios (which I doubt). Depending on your use, you'd probably be better off with a 406 MHz EPIRB or inReach SATCOM unit. That signal goes up.
Shopper  Does the red button have some kind of attachment to the radio ? It seems a little red button cap would be easy to loose ! Thank you
JOEL L  The protective cap is to prevent accidental activation of the emergency GPS transmitter. It is only to be pressed in an emergency because it will send out a distress signal that all vessels in the area are required to respond to. The only time you would press it is if you are adrift alone in the ocean. If that happens, the plastic cover is the least of your worries and if you can't hold on to it and put it in a zippered BCD pocket, so be it. I am sure a replacement cover could be ordered from Nautilus. Keep in mind you will probably never remove this cover for the entirety of your diving lifetime and if you survive, the price of a piece of plastic or the entire GPS unit will be well worth it.
andrew P  I don't know I didn't use the GPS yet
