To many the prospect of diving is exiting and adventurous. It is the reason that many people learn to dive and use the skills that they learn their entire lives. However, many may fear going beyond the conventional depths of recreational diving (12-40 meters) and learn to deep sea dive (40m+). Even though more technical knowledge is required it is possible to safely reach these depths. One of the ways in which this is done is thought reducing the oxygen in the compressed air mixture from 21% to 10%. This is done to reduce the concentration of oxygen that enters the body at higher depths. As you descend in the ocean pressure increases at a rate of 1 atm (atmosphere) every 10 meters. Surface pressure is 1 atm so at a depth of 60 meters the pressure exerted on a diver would be 7 atm. Every time the pressure is increased by 1 atm the volume of the tank is effectively halved, however no gas is lost and thus the same amount of gas is taking up a smaller space due to pressure. So per breath more elements are entering your body. Returning the the 60 meter example, at this depth there is a pressure of 7 atm being exhibited and as such per breath 64x the amount of air will enter your body. Thus 64x the normal amount of oxygen would be taken in per breath, which is a harmful amount, so to reduce this effect and and keep you safe, the mixture is reduced to 10%. This allows you to reach these amazing depths and see the side of the ocean only few have ever seen. See what lives in the deepest depths of the planet. The PADI Open Water Course is the first step you must take, from there the PADI Advanced Diver and PADI Rescue Diver will set you up to become a Divemaster (after experience is gained) and the technical knowledge of this amazing, professional will be available to you.

The PADI courses are taught in Cardiff, Swansea and the South Wales area throughout the year, all equipment is provided and the Open Water course only requires one pool session, a theory exam which is done on the same day and 4 open water dives done over a weekend. Come and experience the most beautiful and rewarding aspect of our world.
