Closed Circuit Rebreather – Technical CCR courses

It would be nearly impossible to explain everything about the Tec CCR diving on this page on the way that you would read all this information till the end of the page ๐Ÿ™‚
For that reason I have collected here few most commonly asked questions and gave short to the point focused answers. If there is something more you would like to ask or do not understand, please contact me and I will be more than happy to help you with.

What is it?

APD Inspiration Rebreather

APD Inspiration Rebreather

Rebreather diving is based on the idea of recycling of the exhaled gas. On this way the diver does not have to carry huge amount of cylinders for long and/or deep dives. The carbon-dioxide is removed from the exhaled gas by a chemical filter (absorbent) and the adequate amount of oxygen is injected to the breathing loop to replace the one the diver metabolized.
Also your breathing gas is optimized at every depth to the highest safe oxygen content, so the inert gas in minimized and this way, your no-decompression time tremendously extended, or in case of decompression diving, your decompression obligations are dramatically shorter.

Where is it coming from and why now?

Inspiration and Evolution CCR

Inspiration and Evolution CCR

Rebreather diving is not a very new thing. It was and is used for long time in research and military fields.
The price of the equipment, its maintenance and proper servicing was very expensive. With time this prices lowered and in last decade they become more affordable and available to the public.
More and more dive organization and associations integrated them into their programs. With time these programs were polished to better safety standards. Recently PADI after observing this “evolution” picked up all the best elements and released its own PADI TecRec courses for Technical CCR diving: The Tec40 CCR diver, Tec60 CCR diver and Tec100 CCR diver course.

Why to do it?

The reasons to dive on closed circuit rebreathers might very by individuals, however some examples are like: extend your underwater time, get closer to aquatic life, stay warm longer and breath moist gas, save money on gas… and many more.

Who can do it?

CCR Diver

CCR Diver

To participate in PADI Tec CCR courses you must meet some minimum prerequisites. For the entry level course, the PADI Tec40 CCR course you must be Enriched Air Diver, Deep Diver, Rescue Diver (before the end of the course) and have minimum logged 50 dives.
On the top of the prerequisites you must have the right attitude of a technical diver.

How much it cost?

The initial investment into the CCR diving is relatively high, however if you are planning to do some deep diving in the future you can make your money back by saving on gas expenses. The maintenance is not significantly more then the open circuit equipment upkeep.

How long it takes?

The courses are about 6-7 days long depending on logistics, however you are required to come prepared, because the theory part of it is extensive. You will home study in advance and during the course you will clarify and apply the information learned previously.

How dangerous it is?

Technical diving is having more potential risk then the recreational diving. A technical diver is also a mindset with which you agree to accept some more risk in exchange for other gains. During the course you will learn how to lower and manage those risks.
