The Deep 40 course is made up of 1 Confined Skills Clinic and 4 Open Water dives;

Day #1

  • Confined Water Fundamentals

Equipment set-up and configuration backplate/wing BCD. Confined water skills include precision buoyancy, horizontal trim, control and propulsion techniques (frog, modified flutter, helicopter turn and back kick), s-drills, descent checks, air-sharing long hose and DSMB deployment.

Day #2

  • Dive 1 – 24m (80ft) to 30m (100ft) – Nitrox
  • Dive 2 – 27m (90ft) to 35m (115ft) – Nitrox

Day #3

  • Dive 3 -30m (100ft) to 40m (130ft) – Nitrox
  • Dive 4- 30m (100ft) to 40m (130ft) – Normoxic/Hyperoxic Trimix (TriOx / Helitrox)

Every dive includes precision buoyancy standards, descent checks (bubble check and s-drill), gas management (SAC), ascent and stop protocols, DSMB deployment and varied emergency scenarios.

All skills developed during this program are applied cumulatively; so the skills learned on the first dive will be applied on each successive dive. A high standard of mastery is applied throughout the entire program and certification is entirely performance-based.
