How does it work?

When you activate the Nautilus Lifeline, a signal is sent to any vessels within a 50 Klm (34 miles) radius who have an AIS (automatic identification system) unit on board. These are on all commercial ships and most larger vessels. Sea Rescue and Water Police included.

Another message is sent to all vessels that have a VHF unit (The unit needs to be set up for this but I will cover that a bit further down) 

What do they see?

Vessels with AIS will get a flashing message on their screen. It will show as a “Man Overboard” and show latitude and longitude co-ordinates.

VHF receivers will hear a warning signal and the screen will flash with a distress message. It will also show latitude and longitude co-ordinates.

How do I set up the send on VHF?

You will need to download the Nautilus Lifeline app and follow the instructions on changing the setting from USA to International. Quite a simple process and easy to follow. One thing, when you have made the changes, the unit will flash a strobe light twice to confirm the settings have been changes. I noticed there were no details on how you confirmed it had been successful.

Do I need to register the unit?

No, it is a personal device and as you are not using two way, you do not need a radio operators’ licence.

The Nautilus Lifeline is a perfect safety unit for all free divers and scuba divers. Only last week we saw what happens when a boat breaks away for the anchor and leaves three divers drifting in the middle of nowhere.
