One Dive Family

Uniting Our Diving Activities Under SDI

Since 1994, International Training has operated with one core commitment—safety, quality, and innovation in diving education. With the creation of Technical Diving International (TDI), we set a new standard for training technical divers. In the years since, we have proved that if you can train technical divers to safely operate in the most extreme and demanding environments, you can elevate safety for every other diving discipline. What we’ve learned through TDI has shaped the way we approach diving instruction across all levels. Now, we are taking the next step in our journey by unifying all our diving activities under a single umbrella brand, Scuba Diving International (SDI), through the One Dive Family campaign.

This unification allows us to better communicate who we are, what we stand for, and how our shared values, first introduced with TDI, continue to guide everything we do across all disciplines of diving.

Since our founding, we have operated under the same core values of safety, quality, and innovation. These principles were first introduced with TDI, where we pioneered technical diving education and set the gold standard in the industry. TDI’s expertise and leadership in training technical divers laid the foundation for everything we do today. Whether you’re a recreational diver, a freediver, or a public safety professional, you have been benefiting from the same standards that have guided TDI from the very beginning.

By unifying all diving activities under SDI, we are aligning our brand to better reflect the values that have always been at our core. This evolution brings clarity to our brand while maintaining the credibility we have built over the last three decades. With One Dive Family, we recognize that the same values of safety and innovation apply to every diver, no matter their discipline or experience level.

We are Sport Diving

A Family of Diving Specialties

Under the SDI umbrella, we bring together a unique family of diving specialties, each contributing to the broader diving experience while maintaining its distinct focus. Whether you’re a recreational diver seeking adventure, a technical diver exploring deep or hazardous environments with TDI, performing crucial underwater operations as a public safety diver with ERDI, or pushing the boundaries of breath control and performance with PFI, you are part of the same family. By aligning all these specialties under one unified brand, we strengthen the connections between disciplines while preserving their unique expertise.

This unity ensures that every diver benefits from the highest standards of safety, no matter what kind of diving they pursue. Our focus on specialized training has always been what sets us apart, and this unification strengthens that commitment.

We are Technical Diving

A Family of Professionals

At the heart of One Dive Family is our network of instructors and dive centers across the globe. These professionals are the backbone of our organization, ensuring that every diver receives the best possible training and support. By unifying our diving activities under SDI, we are providing a clearer, stronger platform for our instructors to deliver consistent, high-quality education to their students.

This unification strengthens our professional community, creating more opportunities for collaboration, innovation, and growth. Whether you’re an instructor specializing in technical diving or a freediving expert, you are part of a global network of professionals committed to helping people explore the underwater world safely.

We are FreeDiving

A Diverse Family of Divers

Diving is a sport for everyone, and at SDI, we celebrate the diversity of our global diving community. One Dive Family is not just a campaign; it’s a reflection of who we are as an organization. From the most experienced technical divers to those just starting out in recreational diving, our community includes people from all walks of life, united by their passion for underwater exploration.

By bringing all our diving activities together under SDI, we are making it easier for new divers to join our family and for experienced divers to explore new disciplines. One Dive Family is about inclusion, accessibility, and fostering a sense of belonging in every diver, no matter their background.

We are Public Safety Diving

A Family-Run Business with a Global Reach

Since our inception, we have operated as a family-run business, and that personal connection has always been at the heart of what we do. One Dive Family emphasizes that SDI is not just a brand, but a community of people who care about one another and share a love for diving. This close-knit, family-oriented approach has enabled us to grow into one of the most respected and trusted diving certification organizations in the world.

As we move forward, we are excited to continue building on the values that have guided us since 1994, ensuring that every diver, instructor, and dive center feels like part of our One Dive Family.

I am not a fan of the brand change and placing all training under the “SDI” umbrella. I learned through a different agency and looked to “TDI” as something special. I have taken several TDI courses and feel that it means something to show a card under the distinctive technical diving variety. I hope mine will not be the only negative feedback on this topic, which you will be receiving.

  Good Morning,
  TDI is where our root origins lie and we are extremely proud of that brand and it will never go away. All we are doing is banding all of our social media platforms in one – so instead of having a social page for TDI, SDI, ERDI, PFI and First Response – we will sandwich all of our socials and blog posts under SDI. This gives us the opportunity to reach audiences in different agencies. So someone who is a new SDI Diver, may see the TDI blog posts or TDI posts and become interested and want to learn more.
  TDI itself is not going anywhere nor is any of the other agencies such as PFI, ERDI or First Response.
  If you have any additional questions or concerns, please e-mail cs@tdisdi.com so we can assist you!

The “One Dive Family” is an exciting consolidation that will dramatically improve the communication and cross-training between the various groups. This will capitalize on the best techniques each group has to offer to make SDI even more diverse while keeping valuable commonality between each specialty.

Does this means TDI (and the other brands) will, with time, cease to exist?

  Hi Jose,
  None of the other brands are being phased out or will cease to exist.
