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.
This course provides the diver with the basic safety, technical and practical knowledge necessary to be a competent full face mask diver and feel comfortable using their system. You will participate in an academic session to learn the features of full face masks, gain familiarity with the system in the pool, and finish by demonstrating the skills during two dives open water.
