DSC capable VHF transceivers can be coupled to a GPS so they know your exact location at all times. When you get a DSC VHF you apply for a unique ID code from the FCC and they store emergency information about you, your boat, and emergency contacts for you and make it available to the Coast Guard.
In case of emergency at sea all you have to do is hit the DSC button on the VHF and it automatically starts sending a distress signal including your ID and position and many other VHF units as well as the Coast Guard immediately know where the boat is thats in trouble. Some of the new chart plotters will display exactly where you are so any boats within range will know exactly how to find you. Some of the more advanced DSC units also have a nature of emergency feature where they can transmit that youre sinking, have a fire, have a medical emergency, or other potential problems at sea so potential rescuers know what to expect before they get to you.
Theres plenty of other fancy tricks DSC can do like programming it so a friend can interrogate your VHF and know where youre at, as well as giving you much better and more secure communications.
