Perfect Buoyancy and SMB Deployment

Buoyancy Control

(Formerly Advanced Buoyancy Clinic) There’s nothing like being in control of yourself and your whereabouts as a scuba diver in the deep blue sea. Divers need to be able to control buoyancy and know the operation, care and custody of the equipment they wear.

Imagine yourself at the end of a dive with no rope to hold onto during your ascent. Let’s go one step farther and say that boats are running around overhead.
With 1,500 psi or less, aluminum tanks float.

Are you confident of your ability to control your ascent?
In class, we discuss how to care for dive equipment and how to properly operate the BC. We spend time in the pool bouncing up and down before finally learning this elusive skill called neutral buoyancy.

You should be able to acquire and maintain Fish Position throughout a dive. This horizontal position keeps our lungs and air supply at the same level and pressure. When in Fish Position, we move less water, use less energy and conserve air.

SMB Deployment: Surface Marker Buoys (SMBs) have become standard equipment for boat divers. And, while most divers can figure out how to inflate one at the surface, to be effective, you need to be able to deploy one using a reel or spool before you even begin your ascent. This requires special training, which we now include with this course.




This course has the following prerequisites:

  • Be at least 10 years old.
  • Possess a minimum of Open Water Diver certification.*
  • Be able to either answer No to all of the questions on the RSTC Medical History form, or secure a physician’s approval prior to taking part.

*Students in one of Harry’s Dive Shop’s Open Water Diver courses may also take this class prior to their open-water training dives.



This course consists of two classroom/pool sessions (mostly pool). If you would like to receive a Specialty Diver certification for this course, you must also complete two open-water training dives. Your instructor will have details.



All classroom and pool training take place right here at Harry’s Dive Shop. We are among the few dive centers in the country with our own indoor, heated swimming pool. This 16-foot-deep pool was designed specifically for diver training. It provides unbeatable convenience and enjoyment.
