Take the PADI Surface Marker Buoy speciality diver course and learn to provide a  delayed marker buoy for ascending divers. This is a skill which all scuba divers should master. Learn how to use a Surface Marker Buoy (SMB), and how to place them to mark boundaries for mapping. Marker buoys may be part of a search & recovery dive, delayed surface marker buoys alert boat traffic to your presence underwater. This is a vital part of scuba diving and a safe way to avoid boat traffic incidents. Maintaining good buoyancy and trim plays a crucial part when you want to deploy a delayed surface marker buoy safely. Learn the safety and hazards of marker buoy lines and reels, as well as swimming underwater with a surface marker buoy.

Who should take this course?

Divers who require a line for visual reference when ascending from a dive, or scuba divers that need to ascend in or around boat traffic. With the delayed surface marker buoy (DSMB) you can make yourself present to overhead traffic, such as boats or jet skis. The DSMB is also a welcoming sight on drift dives for the captain of the boat when picking up divers out of the water. Marker buoys can be placed, when doing underwater mapping of a dive site or place to aid a Search & Recovery operation.
