Unlike a standard surface marker buoy (SMB), which is deployed at the beginning of a dive, a DSMB is typically deployed from underwater, often towards the end of the dive. This allows divers to mark their position and signal their ascent to the surface, providing visibility to boats and other watercraft in the vicinity. The DSMB plays a critical role in preventing accidents, ensuring divers are easily located, and facilitating safe and efficient dive operations.
