Surface Marker Buoy


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.

The ability to deploy a delayed Surface Marker Buoy (DSMB) should be a given for any self respecting “autonomous” diver.
