Delayed Surface Marker Buoy Diver

PADI Equipment Specialist

The Course


Surface marker buoys (SMBs) and delayed surface marker buoys (DSMBs) allow scuba divers to mark boundaries for mapping or search and recovery, alert boat traffic, or provide a line as a visual reference for ascending divers. SMBs make divers much more visible to their dive boat and other traffic on the water.




If you’re at least 12 years old and certified as a Scuba Diver or higher, you can enroll in the Surface Marker Buoy Diver course.

The Learning


You will learn about the various types of surface marker buoys (SMBs) and delayed surface marker buoys (DSMBs) used by divers, the capabilities and limitations of each style, and how to rig and stow them. During two dives, you will learn and practice the proper techniques and protocols for deploying and using SMBs and DSMBs in open water environments.

Important Medical Information


All student divers are required to complete the PADI/RSTC Medical Statement Participant Record form. If you can answer "YES" to one or more of the questions in the Divers Medical Questionnaire section of this form, then you are required to obtain a physician's release, without conditions or restrictions, before participating in any in-water component of the course. Please read the complete details and download the form here.


If you have a copy of this form signed by a physician within 12 months prior to the expected completion date of your course, and your medical history has not changed, then you may provide a copy of it to your instructor. Otherwise, you will need to complete a new form.
