For scuba divers: VHF + DSC + GPS emergency radio!

Postby John » 09 May 2012, 22:29

FYI: There is a new product on the market called the 'Nautilus Lifeline'

Perfect for those doing potentially dangerous dives (7 stars, Taiwan; Blue Corner, Palau etc.)

The Nautilus Lifeline incorporates a personal DSC-version VHF radio into a compact, waterproof enclosure not much larger than a smartphone. With the clamshell latched, the unit can be taken as deep as 425 feet. On the surface, it can be opened to access the radio and GPS-beacon controls, all still waterproof to surface splash. The antenna pops up, and robust push-button controls engage the various functionalities, allowing divers to talk to their base boat with the two-way radio or, if in an emergency, alert boats for miles around to their situation and location.

It accomplishes this remarkable communication through several built-in functions:

Chat button. This can be preselected to a given VHF frequency to allow for two-way communication between divers or between divers and the boat.
Boat button. This button also allows communication with the boat, but it automatically uses Channel 16, the international hail-and-distress channel.
Distress button. Pressing the button for 3 seconds initiates a DCS transmission of distress, sending and displaying an emergency message and your GPS coordinates on other vessels' marine radios within an eight-mile radius.
LCD display. On the side of the unit is a clearly legible readout for GPS position, signal lock, the channel in use, remaining battery power and other important information.
Speaker and microphone. Used to send and receive messages while floating on the surface, these features are actually submersible to 3 feet without the clamshell closed.
USB port. Used for charging, downloading software updates, logging dive sites onto Google Maps or other advanced options.
Battery. Powered by an 1850 mAh lithium-ion battery, it provides 24 hours of power in distress mode.

The Nautilus Lifeline charges via the USB port, which conveniently uses either a standard 110/220-volt AC adapter, or it can be plugged directly into a PC or Mac laptop. The GPS display is easy to read, and the radio's audio is excellent, whether transmitting or receiving. The ergonomics of the clamshell latch, antenna deployment and button navigation are logical and reliable.

The Nautilus Lifeline is unlike any other safety device on the market today. It utilizes modern marine-safety technology and makes it available to every person in and on the water. Divers and boaters are no longer reliant on someone else to send a distress signal in the event of an emergency; that ability can now rest in each individual's hand.


Please note that the RED button requires an MMSI number (Maritime Mobile Service Identity).

Note: Taiwan government does NOT issue MMSI numbers to individuals:

  According to the law, Regulations for Equipment of Ships Article 288-6: Applying for the marine mobile services identity from NCC, applicant should fill in the application form and provide the following documents to NCC:

1. Those ships with Certificate of Nationality:Permit of installation for ship radio communication equipment(or specific approval document), Certificate of Nationality, copy of valid license for ship radio communication equipment(those ships not obtaining licenses may be exempted).

2. Those ships without Certificate of Nationality:Installation approval letter/document from ship and/or fishery administration, Certificate of ship number and related document for purchasing the ship radio communication equipment.

As mentioned above, you could apply for MMSI using the ship with R.O.C Certificate of Nationality and it is not allowed personal to apply for MMSI.

This is NOT an issue for NON Taiwanese!

An MMSI number can easily by obtained on-line for those with USA, Canada, UK, New Zealand nationalities:
