Dive Master Internship

In 1999 Mermaids Dive Centre created the Worlds first Dive Master Internship. The diving industry required a more professional approach to the training of a dive pro and we took the lead. Diving instructor internships followed allowing Dive Masters to progress into scuba diving instruction seamlessly.

All of Mermaids scuba diving internships are FULLY inclusive of agency fees, unlimited diving, full equipment (to keep), dive courses, training, materials and accommodation. Being ALL-Inclusive allows you the professional diver in training to concentrate solely on education and experience. We want you to become the very best diving pro possible and enjoy a wonderful life working in the scuba industry.

Located in Thailand Mermaids offer Dive Master and Dive Instructor training 365 days per year. With a year-long diving season we’re well placed to receive divers any time that is convenient to them. The local diving creates a perfect training ground with several penetrable ship wrecks, deep and shallow coral dives, slack and ripping currents – we have a wide range of diving experiences on our doorstep.

Diving internships allow you the ‘wet-side’ training in order to be a diving professional. Additionally Mermaids operate dry-side scuba repair training in the form of dive equipment maintenance and servicing. We offer a Scuba Engineer Internship that includes diving equipment, compressor strip down, engine rebuild, scuba tank testing and much more. Dry-Side scuba skills are looked at by diving employers very favourably.

If you are looking to become the very best dive pro possible then Mermaids can assist you with your dream. It is our goal to make you as employable as possible as a diver and work prepared. Mermaids have hundreds of ex-interns working throughout the world within the diving industry.

Compressed Air System Management

Compressed Air System Management - Training for the scuba industry


The Compressed Air System Management (CASM) training was introduced in to compliment the Cylinder Testing Course, but also for personnel with responsibilities for day-to-day filling of scuba and scba cylinders.

The course covers:

  • Essential user level maintenance
  • Safe operation procedures
  • Compressors use in accordance with the pressure systems regulations and other relevant legislation

There are no student prerequisites to attend this course

Key Benefits:

  • Prevents costly damage to the compressor unit through lack of operator care
  • Prevents costly damage or destruction of the dive centers scuba tanks through the moistures damage resulting from the damp air supplied from an incorrectly cared for compressor
  • Compressed Air System Management training provides proof of formal compressor and air bank training. When a new compressor stops working, manufacturers often blame the operator or the owner if the person responsible for compressor operation has no training. If the compressor operator has formal training, the blame for compressor failure shifts to the manufacturer or supplier of the unit.
