Freediver levitating between two large rocks

Air-shift equalisation techniques for freediving.

During a freedive, the airspaces inside our body reduce in volume. As we dive deeper, this reduction in volume deceases. It goes without saying that during a dive, we must shift air into the throat and oral cavity to compensate for this reduction. During the first few metres of a dive, most beginners would instinctively

Freediver descends on line

RV and Exhale diving.

The residual volume of the average human is approximately 1/4 of the total lung capacity (TLC). As a freediver starts to descend on a single breath, the residual volume will be reached at 30 metres. Fully exhaling on the surface and freediving on this lung volume is known as exhale diving or RV diving, which

Freediving in cold waters. A useful guide.

Freediving during winter in cold water proves to be challenging for many freedivers, and the truth is most avoid it. Few people are conditioned to the cold and can spend hours in the water. They simply don’t get cold. Cold water freediving comes with many challenges that do not exist in warm water, and overcoming

Instructor uses equalising tool

Equalising for freediving

Equalisation is a relatively big topic in freediving. From beginners equalisation all the way to advanced, covering movements, air shift techniques, control of certain and specific structures / doors, it comes with good reason. And whilst certain air shift techniques may come ‘naturally’ to some, most freedivers will eventually get stuck at some point. For

The Oxygen Advantage for Freedivers

The Oxygen advantage is perhaps one of those books beginner freedivers (as well as experienced and especially instrucors) should pick up after completing their first course. Granted, much of what the author Patrick McKeown writes about is already mostly understood by freedivers, but there are some other specific gasses and chemicals, such as EPO and
