|The original Lifeline Radio
with the two way VHF radio has
been discontinued by Lifeline and superseded with a new product
Marine Rescue GPS.
This new unit does not have the VHF radio communication functions,
but still works as an emergency locator. Size, costs and
feature set is smaller, but still a very valuable piece of dive
equipment to carry.
Presented here is the information on the
original Lifeline units. Go buy a used Lifeline or a new
Lifeline Marine Rescue GPS if you want to be rescued when adrift.
The Nautilus Lifeline
Diver Radio is the best safety equipment advance of the
past decade for divers. The open Ocean is a big space. If you
become separated from the dive boat and the surface conditions are
anything but flat calm you are very difficult to locate, but the
Nautilus Diver Radio changes all of this.
Carried with the diver throughout
the dive this very compact unit is depth rated to 425fsw, at the
surface with the communication lid opened it is "splashproof"
like a regular marine VHF. It has a normal range of about 5
miles, so if you can see a boat, you should be able to talk to
it. The digital emergency signal can transmit much, much farther.
of the Lifeline is very simple and easy using just three buttons
on the radio. The first
button is GREEN and it allows the
diver to talk with the boat on a selectable "chat"
channel for routine
communication. The second button is ORANGE
and this button is preset to
talk on VHF channel 16, which is the marine hailing and distress
channel that most all boats monitor.
The third button is the RED
button under the movable shield. This button activates the
emergency call message and sends out a DSC distress message.
This is a digital broadcast that includes your GPS location and information
about the identity of the radio using the encoded MMSI data.
Because this is a digital broadcast the range of the radio greatly increases over a voice call.
ANY modern Marine VHF radio within
range will receive this digital emergency call and activate an
alarm to alert the receiving radio operators of the distress
call. The USCG monitors the frequency of these DSC calls
24/7 using their Rescue 21 system. On our boat the location
of the emergency call shows up on our GPS network displays
allowing us to pilot the boat right to the spot. The RED
button only functions if you have followed through on the radio
registration and obtained a unique MMSI number for your unit, all
done from your PC over the internet for free - no cost.
The Nautilus Lifeline is extremely
simple to set up and use: You fully charge the unit (using
USB) prior to
first use and check the charge status prior to diving. Using
a simple program, downloaded for free from the Nautilus Lifeline
site, you register your unit and can also update the firmware and
software automatically as needed. You can select the VHF
radio channels you want in your Lifeline for the region you are
going to be diving. All this is done using a simple USB
The pre-dive check is fast and
easy. You push the ORANGE
three times very quickly and the Nautilus does a system check and
gives you a "Good to GO" right on the screen. You
then inspect the O Ring seal and close up the unit and you are
dive ready to 425fsw!
|Open Ocean diving is
risky enough. Being separated from the boat rarely every
occurs in a calm sea state where you are easily seen. The
Nautilus Lifeline Diver Radio could very easily save your
life. We have experienced just how well the Lifeline
works several times while conducting dives from our boat. To
quote one of our divers "It was just like calling for a cab
and the boat pulled right up"!
The MSRP for the no longer
available Lifeline Radio VHF radio unit was $299 and the carrying pouch is $40.
The new Marine Rescue GPS, emergency
broadcast only unit is less cost then the original units and works
extremely well, you just cant talk on the radio with it.
No excuses, get one for open ocean
