If you’re a new boater -- or even if you’ve been boating for years, you’ve probably noticed how many new features are available among today’s available selection of marine radios. It can be a little overwhelming --and far too complicated! There is one feature, however, that strives to be as simple as possible – and that’s called Digital Selective Calling – or DSC. Today, we’re going to look at the proper use of the DSC radio, and how this feature could help save your life by taking the “search” out of “search and rescue!”
First, what is Digital Selective Calling and what are its benefits? DSC is a digital transfer between radios – as opposed to traditional “voice only” radios. This service allows mariners to instantly send an automatically formatted distress alert to the Coast Guard. The Rescue 21 system -- currently being deployed in stages across the country -- allows the Coast Guard to receive these digital transmissions.
