AIM

A BSAC Sport Mixed Gas Diver is competent to:

  • Conduct dives with an open circuit buddy who is a minimum of a Sports Diver (or equivalent), within the restrictions of the lesser, in conditions already encountered by either during their training or previous experience, and under the supervision of a Dive Manager
  • Conduct dives with another mixed gas diver or mixed gas rebreather diver, within the restrictions of the lesser, in conditions already encountered by either during their training or previous experience and within safe diving practices.
  • Conduct dives with an appropriately qualified diver to expand their experience, within the limits of their mixed gas certification, beyond that previously encountered. An appropriately qualified diver would normally be a minimum of Dive Leader or equivalent, but may also be a sports diver who has additional relevant qualifications (e.g. IANTD Tri-mix Diver, IANTD Tri-mix Rebreather Diver, TDI Tri-mix Diver, etc.) gained through formal training with a recognised agency. Such dives should be under the supervision of a Dive Manager who is ideally an experienced mixed gas diver.
  • Dive, subject to a progressive build up of depth experience beyond that encountered during their training, to a maximum depth limit of either 50 metres for the recreational sport mixed gas qualification or 60 metres for the normoxic sport mixed gas qualification.
  • Plan and conduct dives requiring mandatory decompression.
  • Rescue another mixed gas diver from depth and hand over to an appropriate in-water dive support team (It is accepted that the students are able to rescue an open circuit diver to the surface by virtue of the course entry requirements).
  • Conduct dives where other divers, capable of providing assistance and rescue management skills, are available at the surface.

COURSE OUTLINE

The sport mixed gas diver course consists of the following elements:

  • Seven classroom lessons.
  • A theory assessment.
  • A dry practical lesson of 90 minutes.
  • One or more sheltered water lessons of not less than 90 minutes total in-water duration.
  • For recreational mixed gas (50 metres) two open water lessons, dependant on student performance, with a total underwater duration of not less than 120 minutes and an individual lesson duration of not less than 45 minutes.
  • For normoxic mixed gas (60 metres) three open water lessons, dependant on student performance, with a total underwater duration of not less than 195 minutes and an individual lesson duration of not less than 45 minutes.

All practical training in both sheltered and open water includes the achievement of specific performance standards at appropriate points throughout the lessons.

ENTRY REQUIREMENTS

In order to attend this course, students must comply with the following:

  • Be a minimum of 18 years of age.
  • Hold a minimum diver grade of BSAC Sports Diver (or equivalent with a valid 35 metre depth certification).
  • Be able to demonstrate a high level of proficiency in diving. In general terms, this usually entails about 100 logged dives.
  • Be a BSAC Advanced Nitrox Diver & BSAC Extended Range Diver (or equivalent).

EQUIPMENT CONFIGURATION

For Sheltered Water training, the following student equipment configuration is assumed:

  • Twin back cylinders.
  • A single stage cylinder of minimum capacity seven litres for the sport mixed gas recreational assessment.
  • Two stage cylinders of minimum capacity seven litres for the sport mixed gas normoxic assessment.
  • Access to an Alternate Source (AS) ‘octopus’ demand valve, minimum hose length 1.5 metres.
  • Mask & fins.
  • Weight belt or integrated weights where necessary.
  • Spare mask.

When progressing to open water lessons the equipment should also include:

  • Depth gauge and watch/timer or decompression computer
  • Suitable mixed gas for the lesson
  • A delayed surface marker buoy and reel
  • An emergency delayed surface maker buoy
  • An additional surface detection aid (e.g. a folding flag)
  • Protective clothing as appropriate
  • Two Torches
  • Run time slate

FACILITIES

Suitable classroom with teaching aids for formal presentations. Suitable shallow water dive site (10 metres maximum) for skills development. Dive sites with 45 metres maximum for open water dive and 50 metres for the sport mixed gas recreational diver open water assessment. For those opting for the Sport Mixed Gas Normoxic Diver certification are required to undertake a further open water assessment dive to a maximum depth of 60 metres.

QUALIFICATION

Course certification will be issued by BSAC HQ after the event.
