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.

Dive Compressor Strip Down Training Includes:
  • ASSET/IDEST approved Certification establishes the legal competent person status of the technician to work on all compressed air systems.
  • All of the student training manuals are included and access to our technician online database is granted.
  • All compressor spare parts & consumables used during the course.
  • Free Tea/Coffee and high speed Wi-Fi internet to keep you fuelled at the training facility.

There are no formal pre-requisites for the Dive Compressor Strip and Rebuild training.

Dive Compressor Strip Down Rebuild Key Benefits:
  • Opens new fields of employment and hence dive career development.
  • Certification is highly desired by remote employers.
  • Training prevents costly damage to the compressor unit through lack of operator care.
  • Understanding prevents costly damage or destruction of the dive centers scuba tanks.
  • Certification 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. However, if the compressor operator has formal training, the blame for compressor failure shifts back to the manufacturer or supplier of the unit.

Learn how to use and carry out routine servicing of all compressor models, then strip down and rebuild one.

Example of compressors types used during the course:- Bauer Junior, Bauer Capitano, Bauer Mariner, Bauer KAP Series, Coltrisub MCH6, Coltrisub MCH16, L&W Lenhardt & Wagner LW450ES *

* Exact compressor models used for training may vary. Older units are retired and newer units are brought into the technician training workshop.

The diving compressor strip down training is a real asset to diving professionals that require dry-side skills working in a remote area.
