Technical Diving Courses & Cave Diving Courses Overview
Dan’s has been involved with Technical Diving since 1986 when we helped introduce Dive Rite to the Canadian dive market selling advanced gear and learning about higher level diving. Technical Diving Courses were inconceivable in those days, with only cave diving training being available from a small group of Florida cave divers. Usher in the early 1990’s when technical diving finally broke into the market, and when we became the first Canadian certified Nitrox divers and one of the first Nitrox blending and training facilities through IANTD and then TDI.
Since 1996 our technical diving course graduates have graced the water with more finesse, ability and experience than the vast majority of Technical Divers worldwide regardless of agency or instructor.
Our Divers are the most well rounded Divers you’ll find above and below the water, possessing higher skill and abilities, a great sense of team diving values, pride, compassion and a willingness to help mentor newer divers.

Our Technical Diving Courses embrace 3 main areas:

- Gaining a Solid Foundation of Practical and Academic Knowledge started in your Basic Nitrox Course and through a series of academic lessons build on that foundation with each lesson.
- Building on Rudimentary skills while introducing and mastering mandatory skill sets introduced through dry-land drills, confined water training and open water training in a positive, constructive manner, where students can review video footage of the dives with their instructor.
