Calgary Scuba - Calgary, Alberta's Newest Dive Centre - About Us

who we are

TDI/SDI - The Scuba Diving Innovators!

SDI was the first dive training agency to introduce online learning, the first to teach using dive computers, and the first to introduce rebreather training.
TDI/SDI is run by divers, for divers! Why would you settle for second best?

At Calgary Scuba, we are interested in your safety, comfort, and peace of mind. Your training is conducted by our Professional Instructors in a full size pool, where you learn the basic skills before they accompany you to the lake or ocean to safely practice the skills you have mastered. You can actually start today!

Visit us on the TransCanada at 602B 16 Ave NW in Calgary for Scuba Diving Certification, Advanced Diver Training, or Snorkeling and WaterSports needs.

Our Philosophies

  • Class starts with the Instructor

    The Staff of Calgary Scuba are some of the most highly educated in the industry. Our Instructors have been qualified by a minimum of two International Dive Training Agencies to teach you about Scuba Diving.

  • Performance based Training

    We guarantee your success with performance based, not time based training. Should you require additional time and training to master the skills, we provide it.

    Scuba is unlike anything you have ever done before.

  • Commitment to WRSTC Standards

    The World Recreational Scuba Training Council (WRSTC) was founded in 1999, and is dedicated to creating minimum recreational dive training standards for scuba diving certification agencies around the world.

    Our Staff are committed to uphold these Standards.

  • Do what you love,
    do it often

    The very first question we ask our Staff is why do you want to teach Scuba Diving. The common answer is we truly enjoy our sport, and love the look on a students' face when they take their first breath underwater.

    We are here to ensure you have an amazing experience.

Gertie Griffith

"If anyone in my Open Water Class had told me that I would become a scuba instructor ... I would have laughed, and then cried. Like many new divers, I am pretty sure I actually did." As a PADI, SDI and TDI Instructor, Gertie is delighted that teaching scuba is her 'fun' job. There are so many more places to see....Mozambique? Brazil? Who is in?

Marianne Pucheu

Marianne came to us last year by way of the C CMAS (the training agency) that is. "When I dive, I reach a state of serenity. I am mesmerized by the beauty and tranquillity of the life below the surface. I enjoy diving even more when my dive buddies feel the same way."

Gilles Pucheu

Originally from the mountaineering rescue world, Gilles started diving 35 years ago, then 7 years later, the ocean experience let Gilles discover the "Monde du Silence" that he truly understood what Jacques Cousteau meant. Today, Gilles's passion is training divers with CMAS and SDI to be comfortable in the amazing underwater world.

Sean Pendrak

I stopped in here last week and I must say some of the best customer service ever. I was just looking for some basic snorkel gear and the lady that helped me was extremely informative and I never once felt any pressure to buy anything. Highly recommended!

Kimberley Andrews

John created a rescue diver class just for me, and worked it into a very busy and tight schedule. This all came about because John took the time to ask a few extra questions when I came into his shop about my needs, next thing you know I am getting my course completed. Shirley and John set me up with with all the required diving equipment which was high quality and well maintained. Very positive experience with this store.

Don Topper

I checked out this dive shop when preparing for a trip to the red sea. I worked with John. It was an excellent experience. He was able to service our regs and explain gear options. We needed some things at the last min and he worked hard to get us what we needed. I will go back to this shop again without hesitation.
