Product Information
The Nautilus nexGen LifeLine Marine Rescue GPS bundled with the Nautilus Neoprene Pouch and a free DiveCatalog Quick Release Coil Lanyard is a personal VHF search-and-rescue locator that broadcasts your GPS position, accurate to within 1 meter, to AIS-equipped ships up to 34 miles away and to DSC-equipped radios on your own boat. It is depth rated to 425 feet (130 meters) with the dive cap closed and needs no MMSI, license, registration or subscription.
Who it is for
Divers, boaters, kayakers and paddleboarders who want to be found if they surface away from the boat or go overboard. Operation is deliberately simple: undo the latch and open the unit, turn it on, remove the antenna retainer and press the red button. Two modes cover both situations, a Distress Alert for emergencies and a Position Advisory for non-emergency location sharing. The neoprene pouch keeps the unit secured on your gear with a turn lock for fast access and a sewn-in lanyard for secondary attachment.

Frequently Asked Questions
Does the Nautilus nexGen LifeLine need a subscription or registration?
No. The nexGen LifeLine requires no MMSI number, no license, no registration, no subscription and no service fees. It transmits on common marine VHF frequencies worldwide, sending AIS alerts on 161.975 and 162.025 MHz and a DSC message on 156.525 MHz, so any AIS-equipped vessel or DSC radio in range can receive your position as soon as you activate it.
What batteries does it use and how long do they last?
It requires two CR123 batteries, which are not included with this bundle. The batteries are user-replaceable and have a 5 year lifespan, and a full set supports up to 100 hours of transmit time. Keep the o-ring clean so the housing stays sealed, and check the batteries as part of your regular pre-trip gear inspection.
How deep can I take the LifeLine on a dive?
The unit is depth rated to 425 feet (130 meters) with the dive cap closed, and it is IP68 rated. With the dive cap open for transmitting it is splash-proof only, so it is designed to be opened and activated at the surface. It is positively buoyant and floats in salt water once deployed.
How far will the signal reach?
Nautilus publishes a typical range of up to 5.5 miles (about 9 km) to a skiff at sea level, and a maximum demonstrated range of up to 34 miles (about 55 km) to an elevated or hilltop receiving antenna. Actual range depends on the height and sensitivity of the receiving antenna and on sea conditions.
Review summary
Reviewers agree this unit works as a safety signal: the built-in GPS encodes your position onto the marine AIS network, so nearby ships can plot where you are, and it sets off a loud alert on marine radios when triggered. One diver reported taking it to 100 feet with no issues. Several note it is a strong value next to subscription-based alternatives that carry a monthly fee, and one buyer called it a product they hope never to need. It suits open-water and boat divers who want to be found if they surface away from the boat.
