You’ll refine your equipment handling, emergency skills, and decompression planning while strengthening the mindset required for more advanced Tec pathways. Key Details 🗒️ Course duration: 4 sessions / 3 days (9 hours) Session duration: 3–4 hours Schedule: 9:00, 14:00 Number of dives: 4 Maximum depth: 45 m Minimum age: 18 Prerequisite certifications: Tec 40; Rescue Diver; CPR/First Aid within 24 months Logged dives: 50 (including 10 dives deeper than 30 m) Key Skills 🤿 Advanced decompression planning and modelling Use of 100% oxygen for accelerated decompression Refined problem-solving under task load Team procedures at increased depth Emergency management and out-of-gas protocols Precision trim, buoyancy, and propulsion at technical depths Equipment redundancy and failure handling What to Expect 🧭 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. Location 📍 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 refini… ### Essential information _None._ ### What’s included Technical diving equipment for all sessions Confined and open-water training Instructor-led practical applications Use of facilities for setup and debriefing Guidance with decompression planning software Feedback and skill development throughout the course ### What’s not included Tec 45 e-learning package Trimix upgrade fees Medical examination if required Transport to dive sites Accommodation and meals Additional dives beyond course requirements ### Kit list _None._ ## FAQs ### What is the Tec 45 course? Tec 45 is an advanced technical diving programme that expands your ability to complete planned decompression dives to a maximum depth of 45 metres. It builds directly on Tec 40 and strengthens your skills in gas planning, equipment management, and emergency procedures. The course also introduces the use of 100% oxygen for accelerated decompression, improving efficiency during ascent and preparing divers for even deeper technical pathways. ### How long does the course take? The course runs over three days and includes four structured sessions, each lasting about three to four hours. These sessions combine equipment workshops, skill development, and open-water dives focused on technical procedures. Completion times may vary slightly depending on your comfort with the equipment and your progress with ascent control, decompression execution, and emergency drills. ### What equipment configuration will I use? You will train using a technical setup such as twin cylinders, long-hose regulators, an isolation manifold, and a wing-style BCD. Redundant systems are essential at this level, and you will learn how to manage each part efficiently. Your instructor will also cover the use of high-oxygen decompression gases, gas analysis, cylinder labelling, and pre-dive planning procedures to ensure safe and consistent use of the equipment. ### How deep will I dive during the training? The maximum depth for this course is 45 metres. This range allows for limited but meaningful decompression obligations, enabling divers to practise staged ascents, stop planning, and use of decompression gases when appropriate. Dives are instructor-led and follow strict planning protocols to ensure that execution remains controlled and safe throughout the training. ### What prerequisites are required to join? You must be a certified Tec 40 diver or hold an equivalent credential. Rescue Diver certification is required, along with proof of CPR and First Aid training completed within the past two years. Divers must also have 50 logged dives, including at least ten deeper than 30 metres. A medical form signed by a doctor within the last 12 months is compulsory due to the increased risks associated with deeper diving. ### What skills will I learn during Tec 45? You will refine advanced decompression planning, use decompression software, and handle 100% oxygen for accelerated stops. Skills include backup gas management, valve shutdowns, long-hose procedures, and emergency ascent strategies. The programme also develops the mindset of a technical diver, emphasising discipline, problem-solving, and clear communication throughout every stage of a dive. ### Is a Trimix upgrade available? Yes, a Trimix upgrade can be added once specific requirements are met. You must complete the Trimix e-learning modules, pass related exams, and conduct Trimix analysis during relevant practical applications. Two of your Tec 45 dives may then be completed using Trimix once all prerequisites are satisfied, offering a pathway toward deeper technical training. ### Will this course qualify me for deeper diving? Tec 45 certifies divers to conduct single-gas decompression dives to 45 metres. It does not authorise deeper or multi-gas decompression dives; however, it is the essential precursor to Tec 50 or full Trimix programmes. The skills developed here—especially emergency management and decompression precision—prepare divers for the more complex planning required in advanced technical diving. ### What theory work is involved? There are seven knowledge development sections covering decompression models, gas management, oxygen handling, equipment redundancy, and dive planning. Completing these modules before training allows you to apply the concepts directly during the in-water sessions. The theory is reinforced through instructor briefings, dive planning exercises, and practical scenario responses that combine knowledge with application. ### What should I bring to the sessions? Bring swimwear, a towel, dry clothing, and personal dive accessories if preferred. Items such as water, snacks, and sun protection are useful during surface intervals. All technical equipment required for the course will be supplied. If you normally use personal items like a mask, fins, or a dive computer, you may bring them for familiarity, but they are not essential. ## Media - **Primary image URL (resolved in app; may be absolute)**: https://adventuro.com/cdn-cgi/image/width=1200,format=auto,quality=90/https://wp.adventuro.com/wp-content/uploads/2025/12/Screenshot-2025-12-10-at-09.21.12-3.png - **Gallery image count**: 6 ## Limitations - Availability, exact session times, and final price may depend on the live booking flow. - This Markdown is generated from the same catalog fields as the public HTML page at the canonical URL above.
