Tech 40, 45, and 50 Can be combined to provide the more progressive technical diving students with a faster route into expedition diving. Combining the courses provides a more intense learning curve, culminating in the Tech 50 certification. Any one of the courses can be upgraded to Trimix at gas costs only, giving the student a Trimix certificate.
The courses can be conducted in back gas or side mount configuration. Please allow 12 days for the combined package in one configuration and four extra days to include two configurations, allowing for make-up dives. Students will use four tanks with three gases enriched air blends of up to 100% O2. TMX is optional at gas costs. Accelerating the decompression can improve the quality of the decompression schedule. The course schedule is 12 dives, including confined sessions. With eight more dives for the second configuration
Thailand is an ideal place to take a Tec Deep course due to the variety of tec and wreck diving spots
around Koh Tao. This combined course will incorporate diving on a minimum of 6 different shipwrecks.
Below is a breakdown of what the Tec Deep course consists of.
The prerequisites needed to take a Tec Deep course are;
Advanced Open Water & Rescue Diver certification
Enriched Air and deep Diver Specialties
Combined courses in basic side mount
You must also have logged at least 100 dives, including 20 enriched air dives, 25 deeper than 18 metres and 15 deeper than 30 metres. For the combined configuration package, the student must be side-mount certified.
The minimum age to start this course is 18 years old
For divers who are interested in taking the combined courses but don’t meet all the prerequisites, it’s no problem. We will help you reach the required standard to start the courses if you contact us with your current diving details and certification.
DJL owner Tim Lawrence has many years of experience as a technical diver and instructor trainer. Away from teaching, his passion is wreck discovery, and he has an impressive list of located wrecks. These include aeroplanes, tankers, WW2 wrecks, commercial vessels and even a two-thousand-year-old Roman shipwreck. Julia Alberonie is fast catching up within an impressive array of firsts, including but not limited to 700-year-old first Ming dynasty shipwrecks.
With this background, students are guaranteed an exceptionally high level of training from a team that truly understands and respects the potential dangers of tech diving.
The combined courses
the tech courses consist of several parts. There are academics and shallow water skills followed by dives that get progressively deeper.
The course duration is usually twelve days and includes 12 dives with make-up dives possible, but we are happy to extend the time needed if students require it.
Allow four more days for the combined configuration courses
What is covered during the Tec Deep course?
Tec Deep Theory was conducted online at first and improved in the classroom using dry particles and dry workshops
Firstly, Students will study Tec 40-45-50 online, completing the quizzes;
Tech diving equipment configuration
Risks & Responsibilities
Gas & dive planning
Emergency procedures
Techniques & procedures
This will cover topics such as:
Decompression sickness/field neuro exams
