What is the Professional Diploma in Diving Equipment Maintenance?
This professional diploma prepares you to service and manage diving equipment to professional standards. You will learn how recreational, professional and technical equipment works and fails, how first and second stage regulators, valves and hoses are stripped, serviced, adjusted and tested, how cylinders are inspected, cleaned, stored and withdrawn from service, how compressors and filtration systems deliver clean breathing air in line with EN 12021, how wetsuits, drysuits, BCDs and accessories are repaired and conserved, and how dive computers and instruments are diagnosed and verified.
What sets this professional diploma apart: a complete view of the equipment life cycle, from reception and inspection to withdrawal from service; a strong focus on breathing gas, with regulators, cylinders, compressors and air quality; coverage of soft equipment, drysuits and buoyancy compensators; instrumentation and dive computers with post-maintenance verification; workshop organization, SOPs, spare parts and traceability; and a final project in which you design a maintenance service for a real equipment fleet.
