Air Dil, Air Dil Deco, Helitrox (MOD 1)

This is the entry level certification course for divers wishing to utilize a closed-circuit rebreather (CCR) O2ptima, either in back mount counter lung or chest mount models. The objective of the course is to train divers in the benefits, hazards, and proper procedures for diving a CCR and to develop basic CCR diving skills, using air or helitrox as a diluent. This course can be taught with or without decompression.

Course Length: 5 days minimum. Minimum of 60 minutes confined water training, Minimum of 420 minutes open water training to be completed over a minimum of 7 dives. Unit Crossover 2 1/2 days

Maximum Depth: 30meters/100feet no deco, 40 meters/130feet with air dil deco 45 meters/150feet with helitrox deco.

Prerequisites:
No Decompression: 

• Minimum age 18
• Provide proof of 50 logged open water dives. If completing a unit crossover, provide proof of 10 logged CCR dives in the last 12 months. 
• Provide proof as a TDI Nitrox Diver or equivalent from agencies recognized by TDI.
• With Decompression (air or helitrox): 1.

or

• Minimum age 18
• TDI Air Diluent CCR Diver certified or equivalent,
• Minimum of 30 hours and 30 dives on the CCR unit.
• Six months CCR diving experience.

Costs: Diving a CCR is a serious commitment. That is why we require you to own your own rebreather to take this course. Therefore, we make it a no headache process by combining the unit and training into a complete package. Everything except helium (gases, cylinder rental, extend air and scrubber, weights, bailouts, learning materials is included with no additional costs)

• O2ptima CCR (back mount counter lungs) and training is $12,250
• O2ptima CM CCR (chest mount) and training is O2ptima CM w/ Nerd $9,750
• O2ptima CM CCR (chest mount) and training is O2ptima CM w/ Petrel 3 $9,450 .
• Upgrade from Air Dil to helitrox $1100
• Upgrade Air Dil Deco to Helitrox $700
• If additional training is required past the included 5 days, the cost is $450 per day including consumables

Unit Cross Over (Already certified on another CCR)

• O2ptima CM CCR (chest mount counter lungs) and training is $7675* with Shearwater wrist controller or $8375* with Shearwater NERD.
• O2ptima CCR (back mount counter lungs) and training is $10,875*
