The GUE Technical Diver 2 (Tech 2) course is the second in a series of three courses designed to develop technical diving excellence, building upon previously learned skills with a focus on extending essential technical diving skills Tech 2 training focuses on building diving proficiency at increasing depth using Helium diving gases with Oxygen enriched decompression gases. These skills include:
• the use of multiple stages
• the use of Trimix
• the use of greater percentages of Helium
• gas management
• Oxygen management
• decompression
• accelerated, omitted and general decompression strategies
• dive planning
• technical equipment configurations
Course participants will gain experience working with a variety of different gas mixtures for use as bottom mix and multiple decompression gases.
PREREQUISITES
• Must meet GUE General Course Prerequisites as outlined in Section 1.6
• Must be a minimum of 21 years of age
• Must be GUE DIR Fundamentals and GUE Tech 1 qualified
• Must have a minimum of 200 logged dives, with at least fifty (50) dives on double tanks/cylinders; twenty-five (25) of these should have utilized a single stage
• Must have a minimum of twenty-five (25) dives beyond Technical Diver Level 1 qualification
• Must be able to swim a distance of at least 60 feet/18 meters on a breath hold
• Must be able to swim at least 500 yards/457 meters in less than 14 minutes without stopping. This test should be conducted in a swimsuit and, where necessary, appropriate thermal protection.
COURSE CONTENT
The GUE Tech 2 course is normally conducted over a 5-day period, and cumulatively involves a minimum of forty (40) hours of instruction, designed to instill in divers a working knowledge of extended range diving; including physiology, tables and logistics. Special emphasis is placed on extended exposures and on their associated considerations (gas consumption, DCS, Oxygen toxicity, and thermal concerns).
Course requirements include a minimum of six (6) hours of academics, and eight (8) dives, four (4) of which will be critical skill dives and four (4) will be experience dives. Four (4) dives must utilize Helium.
