The current craze in diving is rebreather diving!! With a rebreather, all the air you breath out is captured in the unit on your back and the carbon dioxide is removed, and it is returned to you for breathing again. This means that you do not need as much air, therefore the tanks are only 3liters!
Its not new technology. The “thing” that removes the carbon dioxide is called the scrubber, its just a chemical that reacts with the carbon dioxide and therefore removes it, and was first used in submarines in 1885!
Rebreather diving also offers a different type of diving. During the dives you have to monitor the oxygen content of your air, adding more oxygen to your air if the content gets too low. This is the “technical” aspect with rebreathers, but many rebreathers do this automatically so you just need to make sure that the rebreather unit is doing this properly.
Why do it? Its not about deep diving but about getting up close to the underwater life. When you go diving, the bubbles that you produce scare the fish away, if you produce no bubbles then the fish life will allow you to get closer to them. We can personally verify this with the black tip reef sharks on Rons Point where we had an amazing dive surrouned by 5-10 sharks for ages!
How to get started? As part of becoming a PADI TEC center, we purchased some rebreathers and can offer some try-dives. We will also soon be offering the new PADI rebreather courses aimed at recreational divers:
After this, the next steps are the PADI TEC courses aimed at going on deeper/decompression dives, but thats the subject of another blog!
For more info, keep an eye out on our blog and our website tec diving page.
Yesterday Brendon and Nigel went diving with their brand new Megadolon Rebreather!!
What is a Rebreather?
A rebreather is a type of breathing set that provides a breathing gas containing oxygen and recycled exhaled gas. This recycling reduces the volume of breathing gas used, making a rebreather lighter and more compact than an open-circuit breathing set for the same duration.
There are different types and brands of rebreathers, the one that Brendon and Nigel choose is MEGALODON REBREATHER.
The Megalodon CCR Rebreather is a fine piece of diving machine sporting double heavy-duty o-ring seals on all connections, a heavy-duty aluminum stack where the electronics and Co2 absorbent canister is living in. Individualism is the motto of the day when it comes how to carry the unit ranging from Transpack soft packs to slim or full size stainless steel, aluminum or ABS backplates or even Armadillo sidemount systems. The Automatic Diluent Valve ( ADV ) is a nice safety feature addition during busy events or runaway descents. The Heads Up Display ( HUD ) is a sweet dream to dive with enabling the diver to watch the Po2 at all times, even the busiest ones.
There is a variety of configuations possible with the Megalodon CCR Rebreather depending on personal preferences. The unit is standard back mounted with front mounted cordura counterlungs. The Megalodon CCR Rebreather does not have a standard way of configuration, but can be configured to the divers needs and preferences and to suit the diving environment such as recreational diving, cave diving, technical diving or wreck diving.
SOON SOME PICTURES!!
We are providing support for Tec Deep diving, Trimix diving and rebreather diving. We are also running expeditions to find the elusive Coelecanth fish.
So join us for some exciting dives to 50m and beyond on the deep walls, and help us search for deep underwater pinnacles!
