Tec 40 & Tec 40 Trimix

The Dive Shop is Calgarys most active technical dive training centre. We go above and beyond what's outlines in the PADI Program to give you the best training possible.

The PADI Tec 40 course is where you transition from recreational diving to techncial diving. It is the highest level that can be completed using single cylinder configuration. It is the bridge between no stop diving and technical decompression diving and a pre requisite for Tec 45 diver training.  You will qualify to:

- Plan and make decompression dives with no more than 10 minutes decompression using decompression gas, or not more than 25 minutes or decompression using bottom gas, and not deeper than 40m/130ft. 

- Dive with redundant gas source, either single cylinder plus baiolout bottle Sidemount or back mounted double cylinders. 
-use a single cylinder of decompression gas up to 50% oxygen (EANx 50) for decompression

To enroll in the Tec 40 Course you must meet these qualifications:

• 18 years old
• 30 logged dives (minimum 20 in a drysuit recommended)
• PADI Advacned Open Water Diver (PADI Rescue diver recommended)

The Tec 40 course consists of seven online independant knowledge development sessions, two evening classroom sessions, 4 practical application sessions and 4-6 training dives. You'll learn about technical diving risks and responsibilities, technical diving equipment configurations and useage, team diving concepts, thinking like a technical diver, handling underwater problems, extensive and up to date decompression theory and gas planning. We will guide you on planning decompression dives so you don't just blindly follow your dive computer or decompression software.
