Rebreathers used to be only for military diving, but not any more. CCR - Closed Circuit Rebreathers have sophisticated electronics and are common now in technical diving. Why dive a rebreather? You get longer no stop limits, reduced gas consumption because you reuse most of your exhaled gas, and unmatched wildlife encounters because you don’t release annoying bubbles. 

In technical diving the surface is often inaccessible in an emergency, so tec divers use extensive procedures, equipment and training to manage the added risks and potential hazards. Although founded on extensive open-circuit scuba technology, tec diving has been revolutionized by the development, availability and reliability of closed circuit rebreathers (CCRs). CCRs have numerous benefits and provide tec divers with significantly more time underwater.

Rebreather Types
  • Closed-Circuit Rebreathers (CCRs) recycle all the gas you exhale; only a few bubbles escape during ascents to release expanding gas. CCRs require two gas supplies, a diluent (usually air) and 100 percent oxygen.
  • Semi-closed rebreathers (SCRs) recycle some of the gas that you exhale. Bubbles escape in a stream or small bursts, but not many and not near your face. SCRs only need one gas supply – enriched air nitrox – typically EANx36 or higher.
Standard Rebreather Features
  • Counterlung – A bag that expands when you exhale and contracts when you inhale.
  • Valves – Direct gas circulation in one direction through the breathing hose assembly, so your exhaled breath goes through a chemical scrubber that removes waste CO2.
  • Mouthpiece – Closes and also connects to the bailout valve (BOV), which is an open-circuit second stage regulator hooked up to a cylinder with breathing gas for emergencies.
  • Gas supply – Feeds into the gas flow loop to replenish the oxygen you consume, and to increase the counterlung volume as needed.
  • Oxygen sensor – An electronic module that gas passes through after the chemical scrubber.

At Absolut Diving we focus on the following rebreathers - Poseidon 7, Inspiration and Megalodon. Our Closed Circuit Rebreather Diving courses are available with PADI or TDI.

Tec CCR courses teach technical divers how to use Type T CCRs beyond recreational dive limits.Interested in rebreather training? Then see the CCR course you can learn at Absolut Diving Phuket Thailand. All the prices include the diving gear, standard gases, course materials, certification fees as well as pool and boat dives. At Absolut Diving we want you to get the best TEC education, so we don't leave it with the required amount of dives, No / we ad more dives with each course. That gives you and us the freedom of going more into detail and have more diving fun! The only thing which we would have to charge for is Helium for you and your instructor, our rate is 2thb per liter.
