Technical Training

Intro To Tech Course


This is the process of understanding the technical diving training program and acquiring the equipment and basic technical skills (buoyancy, balance, propulsion, etc.)
(Theoretical training + 3 open waters, and the number of dives available for advanced and drop-up operations can be adjusted.)

Nitrox Course


As an introductory technical diving course, diving using a mixture of gases (22 % - 40 %), which contain more oxygen than air. It teaches the advantages and disadvantages of nitrox and how to use them properly. Qualification can be obtained only with a three-hour theoretical training. Two dives are recommended if necessary.

Advanced Nitrox Course


It is a process of diving with oxygen content of not less than 40 % and not more than 100 % pure oxygen. This has the effect of dramatically reducing the deflation time (compared to air), which is mainly used as a gas for pressure relief. It is also a comprehensive gas management program, such as using a stage cylinder and preparing the gas for use based on the calculation of breathing volume (theoretical training + four open water diving).

Decompression Procedures Course


This is a process of training the theory, planning and procedure of the stage foot pressure diving for up to 45 meters under water. In order to deflate using nitroxs or oxygen without having to deflate it, you must be pre-qualified accordingly, otherwise you can proceed in conjunction.

Extended Range Course


Advanced Nitrox divers and pressure relief procedure divers are pre-qualified by using air as bottom mix to train and experience diving up to 55 meters deep. Typically, you charge a double cylinder and have two cylinders for depressurization.

Tri-mix Course


This is a process to train the value, risk and proper procedures of diving with tri-mix (helium, + nitrogen + oxygen) gas up to 60 meters below sea level. Pre-qualification and equipment preparation are the same as the ERD process. It consists of four theoretical training and four open-water dives.

Advanced Tri-mix Course


This is the highest level of the TDI Large Depth diving training program, diving up to 100 meters deep using tri-mix gases. It consists of four theoretical training and four open-water dives.

Rebreathing training

What is the rebreather?

This is a device that reuses the gases that divers breathe and breathe in water. The biggest advantage of rebreathing is that it allows you to stay underwater for much longer than normal scuba equipment.
In particular, nitrox nitroxyl, which increases the oxygen content, you can experience the benefits of pressure reduction, surface breaks, and more. It also reduces noise and allows breathing in gases that are not cold and have adequate moisture.

Air Deflection (Depressurization)

The second step for recreation divers to use a fully closed rebreather (CCR).

The objective of this course is to provide recreation divers with the benefits, risks, and appropriate procedures of de-pressurize diving with a dilution gas up to 45 m depth using a fully closed rebreather.

Mixed gas dilution

An intermediate course for recreation divers who wish to use a fully closed rebreather (CCR) as a mixture of gases.

The objective of this course is to train recreation divers to the benefits, risks, and appropriate procedures of using a fully closed rebreathing machine (CCR), in combination gas rebreathing diving. Mixed gases contain more than 16 % oxygen and are designed to teach intermediate techniques of rebreathing suitable for technical diving up to 60m using a fully closed rebreather.Upon successful completion of this course, divers will be able to enjoy technical diving with a completely closed rebreather using a mixture of 16 % or more oxygen at a depth of less than 60 meters.

Higher gas dilution

A top-level recreational diver for using a fully closed rebreathing machine (CCR) as a superior mixture.

The goal of this course is to train the diver to use a fully closed rebreather (CCR) to train and re-apply the benefits, the risk, and the appropriate procedure for the resuscitator diving of a higher gas. Successful completion of this course will allow divers to enjoy technical dive with a fully closed rebreather that uses a mixture of gases suitable for their diving plans below 100 meters.
