ClosedLoopDiving is an online supplementary learning platform for technical diving students. Its focus is AI-powered training, using interactive courses, AI quizzes, instant feedback, and progress tracking to reinforce the theory covered in formal technical diving courses. The site repeatedly stresses that it is only a supplementary study tool, not a dive training agency, certification body, or instructor, and that it cannot authorize anyone to conduct decompression diving, CCR diving, or other technical diving activities.
The directions listed on the site include Helitrox Fundamentals, Trimix Deep Diving, and CCR Fundamentals, covering topics such as MOD, EAD, partial pressure, gas planning, decompression planning, gas switching, CCR oxygen management, CO2 absorption, and bailout planning. Helitrox is shown as 17 lessons, 8-10 hours, intermediate level; Trimix as 20 lessons, 12-15 hours, advanced level; and CCR as 15 lessons, 10-12 hours, advanced level. However, all are marked Coming Soon. The learning format appears closer to self-paced interactive online lessons plus AI practice; the copy does not indicate live classes, recorded video, or 1v1 coaching.
The platform offers a free MOD demo lesson without requiring an account and prompts users to create a free account, but it does not disclose full course pricing, subscription options, or payment methods. Certification deserves special attention: ClosedLoopDiving does not provide any diving certificates, credentials, or skills assessments, and completing a course, module, or quiz does not mean a user is qualified to conduct decompression, mixed-gas, or CCR diving. Real certification must be completed through recognized agencies such as PADI, TDI, IANTD, or GUE under the supervision of a qualified instructor.
The main strength is its cautious positioning. It is suitable for breaking down complex, high-risk knowledge into questions and calculations that can be practiced repeatedly. AI-adaptive quizzes, spaced repetition, badges, and analytics can help with knowledge retention, while the built-in MOD/EAD/partial pressure calculators fit technical diving study scenarios well. The limitations are that course availability is unclear, pricing is not transparent, and the founder’s public background appears to be mainly in technology and AI applications rather than in a certified instructor system claimed by the platform. For safety-critical diving education, this means it can only serve as a review tool, not as a complete training loop.
It is suitable for divers currently taking formal technical diving courses, or for already certified divers who want to review theory after certification. It is not suitable for complete beginners who intend to study only from the website and then practice in the water. The site does not state whether access from China, payment availability, or network stability are reliable, so these would need to be tested in practice. Alternatives should prioritize local certified technical diving instructors, official PADI/TDI/IANTD/GUE courses and materials, with ClosedLoopDiving used only as a supplementary after-class practice tool.
