The objective of this course is to train candidates in the proper technique, equipment requirements, and hazards involved in blending nitrox gases for recreational scuba.
The PSA Advanced Nitrox Gas Blender course may be combined with this course at a special 'combined bundle' price of 280.
The candidate will complete a 'Open Book' Exam, blend and analyze 5 Nitrox blends to the instructor’s satisfaction. These blends shall include at least one deco (high FO2) mix. Not all blends should be made starting with an empty cylinder. Where practicable, one blend should include filling twin cylinders. If a set of twins are not filled, the instructor must ensure that the candidate is familiar with twin cylinder isolator manifold operation by providing a “hands-on” session.
