of this thing work.


==================================

Exactly what is it you'd like to know?

You need a DSC capable radio to go with it. All the GPS does is
output your current position to the radio via an interface. If you
activate the DSC button on the radio, it broadcasts your encoced
position to the Coast Guard. Virtually an modern GPS with a data
output interface can do this.
