Train with purpose.
Tech 1 develops deeper decompression diving to 160 feet/48 meters with trimix 25/25, 21/35 or 18/45 and one decompression bottle of oxygen or nitrox 50. Oxygen decompression is limited to one 15-minute cycle, or 30 minutes when using nitrox 50. A stage bottle requires stage training.
As depth and decompression obligations increase, so do the demands of proper gas management, team awareness, and precision execution. This course uses a critical skills approach where dives are treated as real dives with real objectives and evolving failures that require the team to problem-solve together under pressure. Training focuses heavily on mid-water control, ascent discipline, gas switches, valve drills, and handling failures away from the bottom — building the comfort, awareness, and confidence required for more advanced technical diving.
Prerequisites include a minimum age of 21, 75 dives beyond open water, and UTD Essentials of Tech, Rec 2 with Doubles MINI, Techreational, or equivalent with assessment. The instructor verifies all general, fitness and rescue prerequisites before training.
A personal approach.
Train directly with Jay Gardner in a small team, with a maximum student-to-instructor ratio of 3:1. Connect the skills to real diving, with time for observation, practice, and feedback.
Start with a free 15-minute consultation to discuss your experience, course prerequisites, equipment needs, and what you want to achieve. Training dates are arranged together.
