Delayed Surface Marker Buoy (DSMB) Adventure Dive
Many divers wouldn’t think of diving without carrying a delayed surface marker buoy (DSMB), and in some locations it’s mandatory safety equipment. Learn how to properly deploy and manage a DSMB.
Please note, dives you take during this activity can count towards the corresponding Specialty Course, but this is not a certificate-granting course itself.
What You’ll Learn
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.
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.
