Surface marker buoys (SMBs) allow scuba divers to mark boundaries for mapping or search and recovery, alert boat traffic, or provide a line as a visual reference for ascending divers. During two dives, learn the proper techniques and protocols for using surface marker buoys and delayed surface marker buoys (DSMBs) in the local area.
You will learn about the different types of buoys and reels and during the 2 qualifying dives you will practice bottom and mid water deployment of a Delayed Surface Marker Buoy (DSMB) and their use during a dive and on ascent.
