Delayed Surface Marker Buoy (DSMB)

Used on every dive, learn to properly deploy and manage a DSMB.

Depending on the places you plan to visit while scuba diving, boats and currents are two common factors associated with many dive sites. Boaters don’t always recognize that divers are in the area and current can carry you further than expected. Considered as a required piece of safety equipment in some locations, launching a delayed surface marker buoy (DSMB) before you surface can alert others to your location in advance of your ascent. Adding another layer of safety, you can also use the DSMB line to complete your safety stop, which is advantageous in a current or when there are no other visual references.

Marker buoys serve a range of purposes and you’ll learn about common types of DSMB along with the reels used to control them. During the two training dives, you will practice preparing and stowing your DSMB and reel, deploying the DSMB from a stationary position and from mid-water, swimming while towing a DSMB and managing the reel and line, and making a safety stop using the DSMB line.
