BSAC Sports Mixed Gas Course  CCR


Are you an experienced closed circuit rebreather (CCR) diver but want to extend your range to 50m?

The benefit of using gas mixes containing helium is controlling to an extent, the effect of nitrogen narcosis. The narcotic effect of nitrogen becomes debilitating as depth increases. Controlling the narcotic effect of the gas at depth enables improved awareness, therefore safer than deep air diving.

This course introduces divers to mixed gas diving using CCR equipment. It teaches experienced divers to use mixed gas to expand their current skills to be able to dive a maximum depth of 50 metres using the most appropriate gas mix - with a CCR unit. The course uses diluent gas mixes of oxygen greater than or equal to 20% and helium less than or equal to 30%.
