surface marker for ocean diving
Deep sea diving or should I say open water diving? In any cases divers will need to be able to signal their position and communicate with the surface by using a surface marker buoy aka SMB, DSMB, sausage or even a bolb!!
At a beginner’s level, surface suport is just the boat captain and maybe his crew, just waitng in the drift to see ‘where’ the client-divers are going to surface from their dive. Pretty basic you’d say…
It should be, as long as it is agreed before the dive, that an SMB must be used and the boat crew know the type and eventualy color of the surface markers in use within that group of recreational divers.
But on the other hand, we’d have the more experienced diver, possibly a technical diver, even a sidemount technical diver 😉 who absolutely need surface support for his or her safety. During your technical diving class with Essential Scuba Training, you will learn how to deploy safely an SMB.
