Being able to provide a marker buoy for ascending divers, using a Surface Marker Buoy (SMBs), or using them to mark boundaries for mapping, search & recovery, even alerting boat traffic of your presence is a vital part of scuba diving.

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.

  • Using a variety of surface marker buoys
