What is technical diving?
Technical diving means going beyond recreational scuba diving limits, but it's also about the challenge and adventure of exploring places that no one else has ever seen. You will learn to dive beyond 40 metres, how to do stage decompression and how to accelerate decompression and/or the use of variable gas mixtures during the dive with specific standardized gear setup.
Why consider technical diving?
For us, it was the ability to see shipwrecks beyond 30 meters and to extend our divetime to see them. Many interesting wrecks like the USS Emmons in Okinawa, lie at depths below 40 metres. Some prefer to see deep reefs that have organisms you don’t find in the shallows. Some people enjoy the challenge and focus tec diving requires. Still others love being involved with cutting edge technologies. These reasons make tec diving rewarding.
So consider making the next step.
The PADI TecRec Program consists of three sub courses: Tec40, Tec45 and Tec50. The number in each course corresponds with the maximum depth divers are qualified to dive in with each level.
Just want to get a feel of what diving in a technical or hogarthian setup feels like? Try Discover Tec.
Discover Tec allows divers who are curious about tec diving to try out a full technical rig in controlled conditions. The emphasis is on trying out tec diving and the standardized setup in tec diving. Discover Tec may be credited towards the Tec 40 course if you meet all performance requirements for the dive. However, skills performance is not required for the course.

Tec 40: This is the first step to entry level technical diving rating you to 40 metres including decompression and higher gas mixes. This course is for those interested in trying limited decompression diving as well as those wishing to progress further. All decompression is based on desktop decompression programmes (pre dive planning) and dive computers (during the dive).
Tec 45: The next step rating you to 45 metres. The next step for continuing Tec diver training, and you'll learn skills intended for Tec50 and beyond. You'll learn to calculate dive plans 'by hand', but the emphasis is on using multi gas dive computers coupled with decompression software.
Tec 50: Qualifies you to dive to 50 metres with full decompression and up to 100% O2 usage. Also allows you to progress onto trimix and extended range diving.
Tec 45: The next step rating you to 45 metres. The next step for continuing Tec diver training, and you'll learn skills intended for Tec50 and beyond. You'll learn to calculate dive plans 'by hand', but the emphasis is on using multi gas dive computers coupled with decompression software.
Tec 50: Qualifies you to dive to 50 metres with full decompression and up to 100% O2 usage. Also allows you to progress onto trimix and extended range diving.
