Extended Range Instructor
Duration: 4+ Hours
Dives: 1 Pool & 1 Ocean
Age: 21+
Course Highlights
- Learn how to instruct students in planning and executing dives to 55 meters, covering both the theory and practical application.
- Teach gas management and how to safely switch between breathing gases at different stages of the dive to minimize nitrogen absorption.
- Instruct students on decompression theory, including the use of accelerated decompression gases like nitrox or oxygen to reduce overall decompression time.
- Cover deep diving techniques such as managing narcosis, understanding physiological limitations, and handling equipment failures at depth.
- Guide students through the complexities of gas planning, including determining the right gas mixtures for deep dives.
- Supervise staged decompression dives, ensuring students master buoyancy control, ascent rates, and emergency procedures.
- Conduct thorough pre-dive checks, emphasizing the importance of redundancy and contingency planning for all aspects of the dive.
Prerequisites
- Minimum age 21
- Provide proof of 250 logged dives, 25 must be extended range dives
- Certification as a TDI Extended Range Diver or equivalent
- Certification as a TDI Advanced Nitrox and Staged Decompression Instructor or equivalent
- Must have certified 10 students in advanced nitrox diver or decompression procedures diver, a minimum of 5 must be decompression procedures divers
What You Learn
- How to teach students to safely conduct extended range dives using air and nitrox, with a focus on gas management and switching during the dive.
- Methods for guiding students through the selection and use of multiple cylinders, and how to manage decompression gases to optimize their dive profiles.
- Conducting classroom sessions on the physics and physiology of deep diving, narcosis, and gas laws, as well as emergency management procedures at depth.
- In-water training on managing decompression stress, handling out-of-gas scenarios, and maintaining neutral buoyancy during staged ascents.
- Instructional techniques for teaching gas analysis, cylinder labeling, and the configuration of twinset or sidemount equipment.
- How to demonstrate and guide students through problem-solving exercises, including handling equipment malfunctions and managing dive emergencies.
- Post-dive debriefing techniques to ensure students understand the intricacies of their dives, their performance, and areas for improvement.
HOW TO BEGIN?
Self-Study
Choose your preferred self-study option: receive a comprehensive course manual or detailed instructions via email to begin your learning journey. Study at your own pace before arrival to ensure you’re well-prepared. Once on-site, you’ll join classroom sessions with your instructor to review the material, clarify concepts, and solidify your knowledge, setting the stage for successful hands-on training.
Self-Study time commitment: 10-14 hours
With Your Instructor
Engage in practical, hands-on training with your instructor. You’ll develop and refine essential skills, covering everything from equipment setup to advanced diving techniques. Your instructor will guide you through real-world scenarios, ensuring you’re fully prepared to dive independently. This immersive training builds your confidence and competence, equipping you to safely and efficiently explore the underwater world.
Diving time commitment: 4 Days
