It's my impression that the 406 alerts the system. If you are not using a GPS equipped EPIRB, the 121.5 signal gives the rescue people a signal to home in on once they get close.
We still have a small 121 on board in our dink.
Also, it IS legal, in an emergency, to transmit on ANY AND ALL frequencies.
