Scuba Buoyancy Masterclass Series #8 THE BALANCED RIG by Andy Davis When considering the configuration of their scuba equipment for precision buoyancy and weighting, scuba divers should pay heed to the safety issues arising from having non-ditchable weight.  To mitigate those potential problems, it is worthwhile to devote some attention to the principle of a […]

Scuba Diving Buoyancy

Scuba Buoyancy Masterclass #7 ASCENT, DESCENT & BOTTOM PHASE by Andy Davis Scuba buoyancy plays an important role in 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 of scuba buoyancy control on the safety and enjoyment […]

Breath control for scuba diving lung volume

Scuba Buoyancy Masterclass #6 SCUBA BUOYANCY AND BREATHING by Andy Davis 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 rarely noticeable on a scuba dive. The Lungs are […]

Scuba Buoyancy Masterclass #5 PRECISION TRIM & POSITION CONTROL by Andy Davis 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 an angle (upwards or downwards) that will interfere with […]

scuba diving Weighting

Scuba Buoyancy Masterclass Series #4 PERFECT SCUBA WEIGHTING by Andy Davis Divers seeking perfected scuba buoyancy can achieve precise and correct weighting through the application of several assessment methods.  As the diver progresses in experience, whenever they change equipment or whenever they change diving environments (salt/fresh water) they should re-assess their weighting. During initial stages […]

Trim-Thrust-Buoyancy scuba diving

Scuba Buoyancy Masterclass ACHIEVING GREAT SCUBA BUOYANCY CONTROL by Andy Davis Scuba buoyancy control is determined by a number of different factors, such as breathing control, BCD/Drysuit inflation/deflation, weighting, trim and propulsion. As we know from our initial scuba training courses, our relative buoyancy underwater is dictated by whether the weight of water we displace […]

Scuba diving for fun and relaxation

Scuba Buoyancy Masterclass Series #2 PRECISION BUOYANCY CONTROL BENEFITS by Andy Davis Let’s have a look at 7 specific reasons why effective scuba buoyancy control is critical to the scuba diver: Environmental Considerations The underwater world is a fragile environment and unintended contact from a diver is going to cause some damage. This often happens on […]

Scuba Buoyancy Masterclass Series #1 Scuba Buoyancy Control for Divers by Andy Davis Effective scuba buoyancy control is, without doubt, the most important attribute that a diver needs to develop. Control of your buoyancy has a direct impact on air consumption, comfort, relaxation and the control of descents and ascents – which have direct safety […]
