Course Highlights

  • Learn how to instruct students in planning and executing dives to 55 meters, covering both the theory and practical application.
  • Teach gas management and how to safely switch between breathing gases at different stages of the dive to minimize nitrogen absorption.
  • Instruct students on decompression theory, including the use of accelerated decompression gases like nitrox or oxygen to reduce overall decompression time.
  • Cover deep diving techniques such as managing narcosis, understanding physiological limitations, and handling equipment failures at depth.
  • Guide students through the complexities of gas planning, including determining the right gas mixtures for deep dives.
  • Supervise staged decompression dives, ensuring students master buoyancy control, ascent rates, and emergency procedures.
  • Conduct thorough pre-dive checks, emphasizing the importance of redundancy and contingency planning for all aspects of the dive.
