What PADI Tec 40 actually involves
The gateway to the PADI TecRec ladder. Tec 40 takes you from recreational no-stop diving into the technical world: limited decompression to 40 metres, a single deco gas (EAN50), and the twinset skills, gas planning and team procedures every tech diver needs. Four training dives over three days with a dedicated technical instructor, small ratios and all gear and gas included.
Your schedule
- 1 Day 1
Theory + confined skills
Gas planning, decompression theory, equipment configuration and the DSAT/Buhlmann approach to limited deco. Confined-water session building twinset trim, valve drills, gas switches and S-drills.
- Twinset configuration
- Valve & S-drills
- Gas planning
- 2 Day 2
Training dives 1 & 2
Two open-water dives applying team procedures, gas matching, and switching to a single deco gas at a controlled stop. Focus on trim, buoyancy and situational awareness in doubles.
- First deco stop
- EAN50 gas switch
- Team formation
- 3 Day 3
Training dives 3 & 4 — to 40 m

FAQ
Is Tec 40 the right place to start technical diving?
Yes. Tec 40 is designed as the bridge from recreational to technical diving. It introduces staged decompression, twinsets and a single deco gas in a controlled, limited way — the perfect first step before Tec 45 and 50.
Do I need my own technical equipment?
No. A complete twinset, backplate, wing, regulators and deco cylinder are included. If you own a technical rig you're welcome to dive it once we've checked the configuration.
How is this different from the Deep Diver specialty?
Deep Diver stays within no-stop (recreational) limits to 40 m. Tec 40 crosses into planned decompression — you'll incur and manage a deco obligation using a separate deco gas, in a redundant twinset.
