HOME > Technical Diving Courses


Technical Diving takes you to depths and places where most scuba divers can't go. Technical dive training is demanding and requires commitment from both you and your instructor. There are various forms of technical diving requiring different procedures and equipment configurations.


We run both PSAI Technical Diving and PADI TecRec programs, from which you will find the next step in your diving career, whether you are just entering the technical realm or have already advanced further.

PADI TecRec Logo
PSAI Advanced Nitrox

PSAI Advanced Nitrox course teaches you to conduct staged decompression dives down to the maximum diving depth of 45m utilizing enriched air (nitrox) mixes and EAN50 and 100% oxygen for accelerated decompression. More...

PSAI Extended Range

PSAI Extended Range Nitrox Diver course further extends your depth range. The course is designed for divers who wish to conduct dives to the maximum air depth of 55m using staged decompression techniques. This course uses air as the primary back gas and EAN50 and 100% oxygen as decompression gases. More...

PSAI Advanced Wreck Penetration

The lure is there.  When you're diving along the sunken ship and you see a way in... Penetrating wrecks without proper training is dangerous. PSAI Advanced Wreck course teaches you the proper techniques and procedures. More...

PSAI Trimix Programs

When air is not enough - or too much... add helium. There are three levels in the PSAI Trimix program from the basics of using helium based mixes diving with normoxic trimix to the maximum of 55m to using hypoxic trimix down to 100m. More...

PSAI Cave Diver Programs

Some call cave diving an extreme sport. We may not entirely agree, but cave diving requires skills and extensive training. Here you will find it. Four certification levels from Cavern Diver to Full Cave Diver. More...

PSAI Advanced Buoyancy Control (ABC)

While not technical diving as such, the PSAI Advanced Buoyancy Control course is the perfect way to introduce you to technical scuba diving equipment, twin tanks and skills requirements. Helicopter turns, frog kicks, modified frog kicks, backwards finning... The ABC course is a real eye opener even if you have been diving for quite some time and teaches you the basic skills, buoyancy control and finning techniques you'll need in all forms of technical diving. The Advanced Buoyancy Control is also a pre-requisite for PSAI Overhead programs. Once you've truly mastered your buoyancy, you can be confident that you'll do well in further technical diving courses. More...

PSAI Narcosis Management

Narcosis Management is PSAI's signature program with 50 years of continuous development and perfection behind it. The program is taught on air in seven different depth levels, allowing the diver choice of training depth. During the training divers perform only the underwater skills that relate to the actual real world of diving. More...

PSAI Rebreather Programs

If rebreathers interest you for the lack of bubbles, silence or for maximizing your dive time, ask us about the available rebreather courses. More...

PADI Tec Deep Diver Program

PADI's Tec Deep Diver program consists of three courses: you'll start with Tec40 and proceed to Tec45 and Tec50 courses. If your pre-requisites allow, you may take all three back-to-back or one at the time and continue to build up over time. More...

PADI TecRec courses
PADI Trimix Program

As a technical diver you know about limitations of diving on air. To reduce the effects of narcosis or to go deeper, you need to add helium into the mix. PADI Trimix program has two levels: Tec Trimix 65 and Tec Trimix. More...

PADI Trimix Courses - two levels of Trimix certifications.
How we run
Technical Diving courses

Most courses you start right here in Hong Kong. If you're new to technical diving we'll first get your dive skills up to the required levels you wish to go. This may include pool practice, line drills both on land and underwater and training dives in Hong Kong's shallow water.


The Advanced Buoyancy Control is the ideal first step. When done on technical set-up, the course gives you the skills you'll need in further technical diving training. You also complete all or most of the academic study in Hong Kong.


Deep dives we can't unfortunately really do in Hong Kong, either because of depth requirements or for the fact that they'd be very uninteresting dives...  so for those we need to go abroad. By that time you will have done all the preliminary work and you'll be ready to jump into the exciting stuff.

How long
the courses take

Durations vary depending on which courses you're doing, your initial skill levels and logistics. Traveling is required for most technical diving courses.


The overseas dives of the technical diving courses are arranged a few times a year, whenever there are enough divers joining a trip. 

For deep dives requiring staged decompression, we can do two dives per day so the number of dives in the course gives you an indication on the minimum duration required to complete the open water dives. Please keep in mind, though, that the dive numbers given in the course descriptions are minimum requirements, and the actual number of dives may vary due to logistics and on-site conditions.


Many divers combine courses to get most out of the dive days abroad. For instance, Advanced Nitrox plus Extended Range, or Advanced Nitrox plus Advanced Wreck Penetration make good combinations.

How much
it costs

Costs vary depending on how and where you will be doing your courses.


You'll need a full technical gear set-up plus some specific equipment depending on the type of dives you will be doing; dive lights suitable for overhead environment, lift bags, reels, etc. 


You will also need to travel and pay for the tank rentals, gases and other specific equipment you might prefer to rent.


We quote all technical diving courses as 'Tuition Only'. You will then pay for the dives, travel and other costs as you go.
