Course Highlights

  • Train divers in the use of helium-based trimix blends for deep diving, reducing narcosis and managing oxygen exposure.
  • Teach gas management skills, including the selection and blending of trimix gases, oxygen management, and calculating gas volumes for extended dives.
  • Guide students in the use of both normoxic and hypoxic trimix gases, understanding their applications for various depths.
  • Instruct decompression theory specific to trimix diving, including the use of helium for decompression to reduce nitrogen narcosis and oxygen toxicity.
  • Teach problem-solving skills at depth, handling gas switching errors, equipment malfunctions, and emergencies specific to deep dives.
  • Conduct deep dives with students, focusing on equipment setup, pre-dive checks, and post-dive debriefing to ensure safety and efficiency.

Prerequisites

  • Minimum age 2l
