A delayed surface marker buoy (DSMB), decompression buoy, or deco buoy is an inflatable buoy which can be deployed while the diver is submerged and generally only towards the end of the dive. The buoy marks the diver's position underwater so the dive boat crew can locate the diver even though the diver may have drifted some distance from the ...
A delayed or deployable surface marker buoy (DSMB), also known a decompression buoy, is a soft inflatable tube that is attached to a reel or spool line at one end, and is inflated by the diver under water and released to float to the surface, running out the line as it ascends. This provides information to the surface that the diver is about to ...
DSMB may stand for: Delayed surface marker buoy , an inflatable buoy used by SCUBA divers Data and safety monitoring board , an independent group of experts who monitor patient safety and treatment efficacy data while a clinical trial is ongoing
A scuba diver who deploys a Delayed Surface Marker Buoy (DSMB) at the end of a dive may use a pre-arranged colour code to indicate to the surface support crew if there is a problem for which assistance is required. In some circles a yellow DSMB is considered an emergency signal, and red means OK.
Decompression buoy (DSMB), also known as Delayed surface marker buoy – Inflatable surface marker buoy deployed from underwater; Decompression trapeze – Horizontal bars suspended at decompression stop depths; Distance line, also known as dive reel or guide line – Line deployed by scuba divers for navigation
Surface marker buoy, which indicates the position of the divers to people at the surface. [16] DSMB - (Delayed, or deployable surface marker buoy), or decompression buoy which is inflated at the start of, or during the ascent, to indicate the position of the divers to the surface team, and as a signal that the divers are ascending.

One system common with recreational divers is for one of the divers in each group to deploy a delayed surface marker buoy (DSMB), also known as a decompression buoy, at the end of the dive. This serves to notify the boat that divers are surfacing, and where they are.
A commonly used procedure for ascent in open water when not ascending along a shot line or anchor cable is to use the more recently developed delayed surface marker buoy, or decompression buoy, inflated and deployed at the start of the ascent to notify any vessel in the vicinity of presence and location of the divers as well as helping to ...
