Dive Master Internship

In 1999 Mermaids Dive Centre created the very 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 as 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 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 diving professional 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.

Key Benefits:
  • Prevents costly damage to the Haskel unit through incorrect use/lack of proper maintenance
  • Certification provides proof of formal Haskel pump service & repair training – When a new Booster pump stops working, manufacturers often blame the operator or the owner if the person responsible for the unit has no training. If the pump operator has formal training and the unit was maintained and used correctly, the blame for the system failure shifts to the manufacturer, supplier or earlier repair agent involved in servicing the unit.
