Technician’s Qualification System

The Technician’s Qualification System (TQS) was created to ensure high-quality vocational training and competency assessment for SCUBA equipment technician.

It is the primary scuba service technician qualification scheme in Australia. There are 3 levels of TQS training.


TQS Level One

This is the entry-level certification for a professional scuba equipment service technician. Attendance on a TQS sanctioned course, followed by an assessment of proficiency can lead to this valuable diving industry qualification being issued.

The TQS Level One program provides students with recognised proficiency in the following key areas:

  • Principles of SCUBA equipment function and gas flow dynamics.
  • Technician Quality Control and reporting systems.
  • Compliance with manufacturer technician.
  • Understanding and interpreting equipment schematics.
  • Inspection and fault finding principles
  • Procedures for equipment disassembly and assembly
  • SCUBA regulator tuning, adjustment and testing.
  • Workshop equipment safety.
  • Preparing and delivering service reports to customers.

*Please note this is not a manufacturer’s seminar, but an industry service technician training course. This course is designed to prepare you for any manufacturer’s service seminar.

Course Objectives:

The objectives of the TQS Level One Regulator Service Technician Course are:

  • To develop engineering knowledge of SCUBA regulator design and function.
  • To explain SCUBA regulator function based on pressure differential.
  • To describe factors that reduce the mechanical efficiency of SCUBA regulators.
  • To demonstrate fault diagnostic protocols, based on sequential and logical procedures.
  • To introduce appropriate diagnostic and servicing equipment.
  • To illustrate effective standard workbench procedures.
  • To describe appropriate methods for regulator disassembly and reassembly.
  • To explain appropriate methods for regulator inspection and cleaning.
  • To demonstrate appropriate methods for the testing and adjustment of regulators.
  • To introduce professional service technician standards and codes of practice.
  • To explain the need for producing and maintaining standardized service records.

Prerequisites: 18 years old, Advanced Open Water Diver and Nitrox Diver or equivalent.
Duration: 6 days
Course fee: POA

We use demo regulators, each pre-set with deliberate faults. The idea is to prompt a logical and efficient troubleshooting process to real-world kit problems.
