Big Blue Tech: Rebreather Courses
A rebreather is diving unit that allows you to re-breathe the exhaled gas you have already consumed, unlike open circuit scuba, where you breathe directly from the cylinder and then vent all the gas into the surrounding atmosphere.
We only metabolize around 4% of the inspired oxygen, the balance is exhausted along with CO2 (carbon dioxide). The rebreather captures the exhaled gas and re-uses it by removing the CO2 and re-circulating the oxygen, it also adds fresh gas to the system to keep it at a life sustaining level.
There are three different types of rebreather: SCR Semi-Closed, CCR Fully Closed and Oxygen Rebreathers (not available). The Semi-Closed works on a principle of consistently adding fresh gas to the loop while re-using the exhaled gas. These units also vent a portion of the gas into the atmosphere, and even though this happens the gas supply lasts significantly longer than open circuit (recreational diving).
Once you start diving on a rebreather you many find it very difficult to come back to the dark ages of open circuit diving.

Level I - CCR Diver
Introduction to Closed Circuit Rebreathers
This is for people who want to try Closed Circuit Rebreather diving.
It gives you a chance to use a unit with the help of a qualified instructor. You only need to be Open Water certified to get a chance to do a shallow dive with a rebreather unit.
This is a very safe course and it is done in a controlled environment. This can be accomplished in one short day. It is a good way to see how a rebreather works. If you do like what you have done, you can progress to the next level.
Rebreather Unit Options: Pelagian DCCCR | Drager | Azimuth | Inspiration | Evolution | Kiss
Pre-requisites:
*Certified Diver to 18m
Available Locations: Similan Islands, Phuket, Koh Tao, Koh Samui, Khao Lak, Pattaya

Level II - SCR Diver
Semi Closed Rebreather Course
The length of this course is approximately 4 days. There is one day of theory, one day in the pool and two days on the ocean.
This course gives most people plenty of time to get comfortable with the SCR unit.
You must remember, the buoyancy characteristics are not the same as with open circuit. You will be shown how to assemble and disassemble your unit to develop confidence to achieve it on your own.
The two days on the ocean will provide no less than 150 minutes of bottom time, again to provide ample experience. Don't miss out on the opportunity to dive silent and more comfortable.
Rebreather Unit Options: Drager | Azimuth
Pre-requisites:
* Certified recreational diver to use Enriched air nitrox up to 40%
* Minimum logged dives: 50
* Minimum age: 18 years old
Available Locations: Similan Islands, Phuket, Koh Tao, Koh Samui, Khao Lak, Pattaya

Level III - CCR Diver
Closed Circuit Rebreather Course (Recreational)
This course is similar to the Level II, SCR program except that you will be using a fully Closed Circuit Unit.
Minimum open water time is increased to 180 minutes. The pre-requisites are the same as in Level II, SCR.
Rebreather Unit Options: Pelagian DCCCR | Inspiration | Evolution | Kiss
Pre-requisites:
*Certified technical diver to use Enriched air nitrox to extend no decompression up to 80%

Level IV - CCR Diver
Closed Circuit Rebreather Course (Technical)
For the more experienced certified rebreather divers who would like to do dives beyond the recreational limits.
This level of rebreather diving is obviously considerably more extensive. During the course we will take you to a maximum depth of 50 meters. We will be doing decompression no deeper then 9 meters with a maximum decompression time of 30 minutes.
There are four to five dives with a minimum bottom time of 180 minutes and a minimum run time of 210 minutes. Plenty of time will be devoted to practicing decompression procedures.
Rebreather Unit Options: Pelagian DCCCR | Inspiration | Evolution | Kiss
Pre-requisites:
* Certified technical diver to use pure oxygen to accelerate decompression.
* Level III CCR (or qualifying certification from another organization).
* Minimum logged dives: 100
* Minimum age: 18 years old
Available Locations: Similan Islands, Phuket, Koh Tao, Khao Lak, Pattaya

Level V - CCR Diver
Closed Circuit Rebreather Course (Mixed Gas)
This is the highest level you can reach.
The maximum depth for this course is 100 meters which should satisfy all needs. The minimum time using the unit during the course is 240 minutes bottom time with a total run time of 300 minutes.
To be able to dive these deeper depths you have to definitely be familiar with your equipment and your specific unit. You will have the confidence and ability to plan and execute these dives when you finish this course.
Rebreather Unit Options: Inspiration | Evolution | Kiss
Pre-requisites:
*Certified technical diver to use pure oxygen for decompression
*Certified helium mix gas diver
* Minimum logged dives: 200
