This programme builds on your previous technical diving training and expands your capabilities to planned decompression dives to a maximum depth of 45 metres. You’ll refine your equipment handling, emergency skills, and decompression planning while strengthening the mindset required for more advanced Tec pathways.
The Tec 45 programme begins with seven e-learning modules that deepen your understanding of decompression models, gas physiology, oxygen exposure limits, and the operational discipline required for deeper technical dives. During the practical applications, you will configure technical equipment, practise valve drills, refine long-hose procedures, and strengthen your buoyancy and propulsion techniques.
In-water training includes four structured dives that progress from skill reinforcement to advanced decompression execution. You will plan and conduct dives with staged decompression, apply bailout strategies, and use 100% oxygen during simulated or real decompression procedures. Each dive includes precise ascents, controlled stops, and team-based task management. Your instructor will evaluate your ability to maintain positioning, communicate clearly, and respond effectively to equipment or gas-related emergencies.
The training also reinforces complex problem-solving at depth, requiring divers to maintain composure while managing failures such as free-flows, regulator malfunctions, or lost-gas situations. By the end of the course, you will be competent in conducting decompression dives to 45 metres and will have a solid foundation to advance toward Tec 50 or Trimix training.
Confined preparation sessions take place in calm-water settings ideal for practising equipment drills, valve operations, and emergency responses. These environments minimise distractions and allow divers to focus on refining precision skills before applying them at depth.
Open-water sessions are conducted at dive sites with clear, stable depth profiles appropriate for planned decompression dives. These areas allow safe execution of staged ascents, mid-water stops, and emergency planning scenarios. Facilities nearby support equipment setup, gas analysis, and thorough pre- and post-dive briefings to maintain a professional technical training environment.
Divers must be certified at Tec 40 level or equivalent and hold a Rescue Diver certification with recent CPR/First Aid training. You must have logged at least 50 dives, including a minimum of ten dives below 30 metres, ensuring you have sufficient deep-water experience.
A medical form signed by a doctor within the past 12 months is required due to the physical and psychological demands of technical diving. Completing all e-learning segments before arrival allows you to focus fully on practical exercises and deeper planning requirements during the sessions.
Training is delivered by experienced technical instructors who prioritise precision, safety, and structured development. The teaching approach blends rigorous skill-building with clear explanations, ensuring divers understand not only how to perform advanced procedures but also the reasoning behind them.
The environment supports serious technical training while maintaining a friendly, community-focused atmosphere. Facilities are organised, equipment is reliably maintained, and the team promotes safe learning through careful supervision and progressive challenge. This combination ensures divers gain confidence, competence, and readiness to progress toward higher levels of technical diving.
