All divers diving in Open water should be proficient in the use of Surface marker Buoys (SMB’s) a standard requirement in many diving locations especially in the UK, SMB use is designed as a device to improve diver safety, however improper use can be a real hazard.

SMB’s/Delayed SMB’s are used in a variety of situations:
