DEMA 2025 Seminar Series: How Big Is Tech Diving?

Back by popular demand, Brian Carney once again presented highly anticipated data on the size and scope of the technical diving market. Over the years, his annual analysis has evolved into a cornerstone session for professionals who want to understand where the industry has been and where it is heading. His presentation has become a favorite within the community because it does more than report numbers. It traces the story of technical diving’s global expansion, revealing how training demand, technology, and diver expectations have transformed since the early days of mixed-gas exploration. This year’s session continued that tradition. For the third time in the past decade, TDI released its certification numbers, offering one of the most transparent snapshots available in the diving world. These figures document the steady rise of technical training, the diversification of course pathways, and the increasing influence of advanced diving disciplines on the broader market. By placing historical data alongside current performance, Brian illustrated not only how far the agency has come but also how much the field itself has matured. The data underscores a powerful story. It charts the agency’s sustained growth and highlights key milestones that have shaped technical diving into a dynamic, globally interconnected community. At the same time, it provides a benchmark that helps facilities, instructors, and divers evaluate emerging trends, anticipate future needs, and understand the direction in which the technical diving community is moving. In many ways, the presentation serves as both a historical archive and a forward-looking roadmap, capturing the momentum of an industry driven by innovation, exploration, and a relentless pursuit of pushing boundaries. 🔔 Don’t forget to LIKE, SUBSCRIBE, and HIT THE NOTIFICATION BELL so you never miss an update from the #OnediveFamily! https://www.youtube.com/c/SDITDIERDI SDI - Scuba Diving International: Linkedin: https://www.linkedin.com/company/scuba-diving-international-sdi Facebook: https://www.facebook.com/SDIdivers/ Instagram: https://www.instagram.com/sdidivers/ For more info on Dive Courses: https://www.tdisdi.com/ *Please note that translations in all of our materials are created by a process that utilizes translators in combination with automatically generated content.
