Commercial SCUBA Diving Equipment (Class IV) is a core course for divers entering or working in commercial SCUBA diving environments. It provides the essential knowledge and practical skills required to correctly select, use, operate, and maintain personal diving equipment and SCUBA systems to support safe and efficient diving operations.
Commercial divers rely on properly functioning equipment to reduce risk, improve task performance, and ensure safety underwater and at the surface. This course focuses on understanding equipment purpose, legal and operational requirements, correct use procedures, and routine care practices that prevent failure and extend equipment life.
Key areas covered include:
-
Understanding the goals and scope of commercial SCUBA equipment training
-
Identifying and using surface swimming equipment and personal protective equipment (PPE)
-
Selecting and using personal gear such as masks, snorkels, fins, knives, and weight belts
-
Understanding diving suits, harness systems, and safe equipment configuration
-
Understanding commercial SCUBA equipment including cylinders, regulators, gauges, and buoyancy compensators
-
Applying legislative and safety requirements for SCUBA use in commercial environments
-
Understanding SCUBA limitations and risk controls
-
Learning preventative maintenance, cylinder filling and storage rules, corrosion risks, and inspection requirements
-
Applying safety flashes and best practice safety precautions
-
Demonstrating competence through practical application and equipment readiness checks
By the end of this course, you will be able to use and maintain commercial SCUBA equipment safely and correctly, supporting professional diving standards and reducing risk during operations.

- Personal Diving EquipmentObjective: Develop the knowledge and practical skills required to select, use, and maintain personal diving equipment and surface swimming gear to support safe and efficient commercial diving operations.
Knowledge: Explain the purpose, correct selection, fitting, and safe use of surface swimming equipment, PPE, personal gear (mask, snorkel, fins, knife, weight belt), diving suits, harness systems, and basic care and maintenance requirements, including common hazards caused by incorrect use or poor equipment condition.
Skills: Demonstrate correct personal equipment competence by selecting appropriate equipment for conditions, fitting gear correctly, conducting readiness checks, and applying safe handling and maintenance practices for operational use.11 - SCUBA EquipmentObjective: Develop the knowledge and practical skills required to identify, operate, and maintain commercial SCUBA systems safely and effectively in Class IV commercial diving environments.
Knowledge: Explain the key components and functions of commercial SCUBA systems including cylinders (steel vs aluminium), valves, regulators (first and second stages), pressure gauges, buoyancy compensators, SCUBA limitations, legislative requirements, preventative maintenance practices, filling and storage rules, corrosion risks, inspection requirements, and safety flash lessons that prevent equipment failure and injury.
Skills: Demonstrate SCUBA equipment competence by applying correct selection and use procedures, performing pre-dive equipment checks, identifying unsafe conditions or faults, implementing safe cylinder handling and storage practices, and applying preventative maintenance and safety controls to support operational readiness.17- 4.1SCUBA
