Digital Selective Calling has also been selected as part of the Global Maritime Distress and Safety System (GMDSS). This service will let you instantly send a Distress call with GPS position to the US Coast Guard and other vessels within range of the transmission. DSC will also let you initiate or receive distress, urgency, safety, position information and routine calls to or from another vessel outfitted with a DSC transceiver.
