DURATION
Two days: Day 1 - Classroom studies, Day 2 - Two Open Water Dives
ENTRY GRADE
* BSAC Sports Diver or similar (see BSAC SALT table) + 20 additional dives
* BSAC Nitrox Diver (or equivalent)
* Current evidence of Fitness to Dive
FACILITIES
* A suitable classroom for theory lessons, with enough space to spread Nitrox cylinders for practical analysing lessons.
* A suitable open water site for practical diving on Day Two.
* The following equipment will be required for the practical dives:
* 1 Nitrox cylinder per student (minimum 10 litre)
* 1 Pony cylinder (or doubles) per student
