Nautilus Lifeline Marine Rescue GPS including 2x CR0123 batteries

Update 09/04/2024: Nautilus Lifeline is currently being redesigned and upgraded. We are out of stock of the "old" style one at the moment. If you would like to know when we're back in stock with the new Nautilus Lifeline, send us a line and we'll let you know when we're restocked.

The Nautilus Marine Rescue GPS is less than half the size of our original radio and is incredibly simple to use. Simply undo the latch and open, turn on, remove the antenna retainer, and press the red button. That’s it! Your GPS position accurate to 1.5 metres and a man overboard distress message will be broadcast to all AIS equipped ships up to 34 miles away, as well as a special DSC message to the marine radio on your own vessel. Your Nautilus GPS floats and is waterproof in all sea conditions. Just keep the o-ring clean and forget about it for the next 5 years! Don’t get left behind!

It’s more than a Personal Locator Beacon (PLB)

Nobody should be on the water without one. Compact. Super tough. Affordable. You might not think you need one until you do!!

You shouldn’t have to pay for a subscription in case you have to call for help.

Get Help Fast

Nautilus Marine Rescue GPS is faster and safer than satellite technology. Press the red button to send your distress alert directly to all boats, ships, and rescue craft around you. Your position sent is accurate to 1.5 metres!

Position Advisory

Perfect for letting boats know where you are without triggering any kind of emergency response.

Diver Tough

The Nautilus GPS works everywhere in the world. At its affordable price, we want EVERYONE on the water to have one.

    International Shipping

    At the moment, our website is only set up to ship within New Zealand. If you live outside New Zealand, please contact us and tell us your full shipping address, phone number, and what you want to purchase. Please note that our free shipping offer applies to NZ shipping only. Our preferred method of shipping internationally is DHL.

    How long will it take for my order to arrive after I make payment?

    That depends on where you live and whether we have an item in stock or not. While we do have many items in stock, we don't carry everything. If you need an item in a hurry, it's a good idea to contact us and find out if your item is in stock.

    If we have it in stock, we can usually send it out as soon as we receive payment, or you can pick it up. If an item is not in stock, we'll need to order it from our suppliers, which means it can take 1-2 weeks to arrive at your door (usually closer to a week).

    Sometimes delivery can take longer, if our manufacturers are out of stock, for example, but this is unusual - we let customers know as soon as possible if something like this happens.

    How do you ship my NZ orders?

    We use New Zealand Post Courier to ship orders. You may organise an alternative with us by contacting us directly. New Zealand Post aims for next-day delivery nationwide between major towns and cities in the North Island. South Island delivery can take two days. If you require next-day delivery in South Island, choose the express shipping option for the South Island. If you spend over $250 get your shipping for free!
