Scuba Cylinder Specifications for Buoyancy and Weighting Calculations When scuba divers calculate their buoyancy with an aluminum cylinder,  it is essential for them to know the relative buoyancy characteristics of their chosen cylinder – at full pressure capacity and also at their minimum reserve (500psi). The following tables provide buoyancy information on the common Luxfer [...]

Scuba Buoyancy Masterclass #7 ASCENT, DESCENT & BOTTOM PHASE by Andy Davis, PADI TecRec, ANDI, BSAC and SSI Technical Diving Instructor Scuba buoyancy plays an important role within all the phases of a scuba dive.  In this article, we look in detail at particular elements of a scuba dive, with an emphasis on the impact [...]

Breath control for scuba diving lung volume

Scuba Buoyancy Masterclass #6 SCUBA BUOYANCY AND BREATHING by Andy Davis, PADI TecRec, ANDI, BSAC and SSI Technical Diving Instructor Breathing plays a critical role in scuba buoyancy control.  As we breath, the inflation and deflation of our lungs is continually affecting our buoyancy, but providing the breathing remains steady, slow and controlled it is [...]

Scuba Buoyancy Masterclass #5 PRECISION TRIM & POSITION CONTROL by Andy Davis, PADI TecRec, ANDI, BSAC and SSI Technical Diving Instructor Whenever we use our fins for propulsion in the water, we create directional thrust. If our body is not horizontally trimmed (‘flat’) in the water, then we will be accidentally directing that thrust at [...]
