Agree the vast majority of boaters dont use DSC here in the states.
DSC was supposedly up and running in Europe almost a decade before the US. Anyone have experience using it there?
If buddy boating or just in a really radio congested area it might be the ticket to learn how to, especially if cel reception is bad.
I have read of people using it and loving it once used to it, but it is a small number of people in comparison to all boaters.
Probably like features on all electronic gadgets these days, they are there because it is easy to incorporate into the design (and DSC was designed for other things besides just alerting people) more than z demand for them.
So some people jump on them while others never see the need.
Probably the best thing for thd max decibel alarm would be an ambient noise sensor like motorcycle radios have.
