This section will cover the use of GSM cellphones, using our Bluetooth Nokia 6820 as an example of the new generation of  'SmartPhones' that can manage voice and data transmissions in the marine environment.

 

Our 'clamshell' GSM phone also acts as a wireless modem for my laptop - see how I can hoist it to the top of my mast when the reception needs a boost.

For those out-of-the-way places where there just ain't no cell reception, you'll see how I use my Globalstar satellite phone to fill the gap. It works almost anywhere, with a large constellation of orbiting satellites that automatically switch your signal to the best one.

And let's not forget about VHF radio. In times of extreme emergency, you may be too rattled or physically unable to dial a number, and it sure is nice to just press a button and talk to someone in a hurry.

 

We'll also take a good look at the clever new GPS VHF units that can automatically flash your precise location to the Coast Guard in an emergency.

These GPS capable units should really help improve safety on the water, as the Coast Guard reports that one of the biggest challenges for their SAR (Search and Rescue) units is determining where callers are located. Many people have difficulty explaining their precise location, especially in an emergency.
