Take your diving further by becoming a technical diver

Technical diving is a step beyond recreational scuba diving. It is training to allow you to plan and execute advanced dives beyond recreational scuba diving limits. Here at Oceans Unlimited and Go Pro Costa Rica we offer the only technical dive programs in Costa Rica with our in house TDI instructor and DSAT Tec Rec instructors and instructor trainer. We offer a selection of DSAT Tec Rec and TDI courses here at student level up to and on demand instructor level programs.  Check out our different course options below.

Tec 40

The PADI Tec 40 course is where you transition from recreational scuba diving to technical diving. It’s a great place to start because it’s the first subdivision of the full PADI Tec Diver course and bridges the gap between no stop diving and full technical deep decompression diving. You gain experience and begin building the knowledge and skills you need to continue your tec diver training. You will qualify to make limited decompression dives to 40 metres/130 feet.

General Course Information

Number of Dives: 4
Duration: 3-4 days
Prerequisites: PADI Advanced open water certification or equivalent

PADI Enriched air diver certification or equivalent

PADI Deep diver certification or equivalent

Minimum 18 years old and at least 30 logged dives. 

Tec 45

The PADI Tec 45 course is the second part of the full PADI Tec Deep Diver program. You’ll extend your depth limit to 45 metres/145 feet and learn to plan and execute repetitive decompression dives using a single stage/decompression cylinder. It puts you in a complete tec diving rig, which can be either backmount or sidemount. You’ll also make accelerated decompression dives using EANx or pure oxygen. This is a course where you’ll rise to the challenge and make the commitment to become a technical diver.

What will you learn about?

During this program you will focus on the function and maintenance of tec diving equipment and associated issues. You continue fine-tuning gas planning and calculating accelerated decompression stops. Plus, you learn to think like a technical diver.

General Course Information

Number of Dives: 4
Duration: 4 days
Prerequisites: PADI Rescue diver certification or equivalent

DSAT Tec 40 or equivalent

Minimum 18 years old and at least 50 logged dives of which 12 dives are deeper than 18m and 6 are deeper than 30m. 

Tec 50

The third part of the full PADI Tec Deep Diver program is Tec 50. As a Tec 50 diver, you show that you’ve developed competency as a tec diver and have the skills to dive to a maximum of 50 metres/165 feet. You know how to make extended, accelerated decompression stops using up to two gases. It’s not easy to reach this level and earning your Tec 50 certification opens the door to deeper diving expeditions.

What will you learn?

The Tec 50 course includes two knowledge development sections, three practical application sessions and four open water dives. A primary focus of this course is mission planning and execution. You also learn more about handling emergencies and how to think like a technical diver.

General Course Information

Number of Dives: 4
Duration: 4 days
Prerequisites: DSAT Tec 45 or equivalent

Minimum 18 years old and a minimum of 100 logged dives, with at least 20 dives on enriched air nitrox deeper than 18 metres/60 feet and 15 dives deeper than 30 metres/100 feet

TDI Advanced Nitrox

The TDI Advanced Nitrox Course qualifies divers to use enriched air nitrox from EAN 21 through EAN 100 percent within your current certification level to a maximum depth of 40 metres/130 feet during dives that do not require staged decompression. Often taught in conjunction with the TDI Decompression Procedures course, this can be considered the foundation of your technical diving career. What will you learn?

This course offers a more in-depth look at diving with nitrox including:

  • Physics and physiology relating to diving with gas mixes containing more than 40% oxygen
  • Gas planning, dive tables, dive computers, oxygen limitations, nitrogen limitations
  • Equipment considerations, cylinder labeling, analyzing nitrox mixtures, gas blending procedures, and oxygen service ratings for using gases with more than 40% oxygen

TDI Decompression procedures

As sport divers, planned decompression is not something that we do or have been taught.The TDI Decompression Procedures Course prepares you for planned staged decompression diving. With a maximum operating depth of 45 metres/150 feet, this course is your first step beyond the normal sport diving limits. The TDI Decompression Procedures Course combined with the TDI Advanced Nitrox course form the foundation of all other technical courses. After these two courses and some additional experience, the stage has been set for you to move onto additional technical levels.
