Objective: Deploy a surface marker buoy (SMB) while on the surface.
Value: An SMB is a signalling device. It lets those on the surface know your underwater location. It is frequently used to increase diver safety.
How It’s Done:
- Your instructor will demonstrate the deployment of an SMB while on the surface.
- If you are diving in an area that requires deployment of the SMB while you are underwater, your instructor will teach you how to do it.
