The other (important) bit I have always wondered about is: Do we buy a cheap RDF to pick up the 121.5 transmition for our MOB EPIRB's? Otherwise they are useless as tits on a bull if a crew goes over with one of those pinned to them. |
There are at least 2 levels as to how these are marketed.
You have a receiver that alerts you that someone is overboard.
You have a receiver that alerts you that someone is overboard and hits the mob button on your gps. (most have this capability now?)
You have a directional receiver (rdf as you suggested) to lead you back to the transmitter.
