CCR diving

WDT Dive proposes different Closed Circuit Rebreathers CCR diving programs:Rebreather experience, CCR diver (MOD1), Normoxic CCR diver (MOD2), Trimix Diver (MOD3), Expedition trimix CCR diver (MOD4), wreck CCR diver, Cave CCR diver.
Closed Circuit Rebreathers are used in Recreational and Technical diving, they give the diver the ability to stay longer underwater, to go deeper and further. The training has to be done for each environment. We are not selling certification cards but we provide a realistic training for our rebreather divers. It has to be done and repeated all along your diving careeer. Today we have the technology, we need trained human beings to use it. NO SHORTCUT ALLOWED! 

Rebreather Experience

This Program is designed to introduce the diver to the basic concepts of Diving with Rebreathers, and to provide a practical confined water and optional OW exposure for swimming with a Rebreather. It is not a Qualification Program.

Closed Circuit Rebreather Diver (CCR)

CCR Diving program is designed to train competent divers in the safer use and technology of CCR diving requiring up to 15 minutes decompression. It is also especially useful to train divers who wish to dive up to 160 fsw (48 msw) if using diluent with helium or 140 fsw (42 msw) if using air as a diluent. The training requirements here-in are IANTD minimums.     


Normoxic Trimix Closed Circuit Rebreather Diver

Normoxic Trimix CCR program is designed to train divers who wish to dive between 90 fsw (27 msw) and 200 fsw (60 msw). But do not wish to breathe air diluent below 90 feet (27) msw on CCR. In the safe use of the CCR for dives using Normoxic helium-based gas mixtures for diluent, and for stages.This program qualifies divers to perform Trimix Dives outside of training up to 200 fsw (60 msw)

Trimix Closed Circuit Rebreather Diver

Trimix CCR Diving program is designed to train divers in the safer use and technology of Rebreathers for deep diving to depths in excess of 200 fsw (60 msw). This program qualifies divers to perform Trimix Dives outside of training up to 330 fsw (100 msw)

 Expedition CCR Trimix Diver

Expedition Trimix CCR program is designed to train CCR divers already involved in deep diving activities to more safely conduct exploration dives requiring extended decompression profiles and helium-based gas mixture. This program is not intended to be used as an enticement to divers who are content to remain in normal Trimix diving limits. This program qualifies divers to perform Trimix Dives outside of training up to 400 fsw (120 msw).

CLosed Circuit Rebreather Cave Diver.

CCR Cave Diving program is designed to train divers in cave diving while using CCR. Emergencies and behavior are totally different from open water to a cave environment. An open circuit cave diver should follow a CCR Cave diver class before to cave diving using a closed circuit rebreather. A CCR diver must follow the full CCR Cave diver program before attempting ANY cave dive using a closed circuit rebreather.

Note: Candidates must own their unit. Gas, rental equipment, dive trips are not included. Contact us for more information on training fees.

Equipment needed for Wreck and CCR Cave diving with a CCR

1. All students must be taught the concept of gas matching based on oxygen metabolism.

2. Bailout adequate to allow 1 ½ divers to exit the cave on OC must be carried by the dive team.

3. A stage decompression cylinder containing oxygen is recommended for deco as a back up to the system.

4. Bailout stages must be configured to ensure easy handling off to an out of gas diver. A 5 foot 1.5 meter hose is recommended. IANTD tanks labels for mix content

5. Each gas source must have its own dedicated submersible pressure gauge.

6. A primary BCD is required. Back flotation is recommended.
