Surface marker buoys (SMBs) are one of the most useful items of diving kit you’ll ever own, and having the ability to use an SMB is vitally important when you are coastal diving.
They can allow scuba divers to mark boundaries for mapping or search and recovery, alert boat traffic, signal for assistance underwater, provide a line as a visual reference for ascending divers, and provide an emergency source of buoyancy.
If you’re at least 15 years old and have earned a PADI Adventure Diver certification or higher, you can enrol in the Surface Marker Buoy (SMB) Specialty course.
During two dives, you’ll learn the proper techniques and protocols for using surface marker buoys and delayed surface marker buoys (DSMBs) in the local area using a range of buoys and techniques.
This is a full PADI Speciality, and counts towards your Master Scuba Diver qualification.
