This is the second entry level certification course for divers wishing to utilise
a Closed Circuit Rebreather (CCR) for mixed gas diving using a Helitrox diluent. 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, to a maximum of 45 metres, using an air/nitrox/helium diluent for formal decompression diving. Students are permitted to utilise a diluent and bailout mix with no greater than a 35% helium content and no less than a 21% oxygen content and can use up to 100% oxygen for decompression.

Currently, all training is done using AP Inspiration XPD, EVP, EVO & Classic/IQSub XCCR/ScubaForce SF2 rebreathers.

Some units are available to be used for the duration of the course and can be included in the price of the course if required. We are an authorised dealer for all units used in the teaching portfolio and can advise you on and arrange the purchase of your new unit.

Please have a discussion with your instructor about all these options.
