True buoyancy control has the ability to transform a diver’s experience underwater, improving air consumption, comfort and level of enjoyment. This specialty is designed to increase the open water diver’s understanding of the factors that influence buoyancy through effective weighting, trim, breath control and finning techniques. The added benefits to the marine environment cannot be overstated!

There is nothing quite like the feeling of being able to effortlessly glide through a wreck or get up close and personal for that great photo. The Advanced Buoyancy Control Specialty can help you do just that!
