About Blue Marlin Dive Tech

The leading technical dive school in Indonesia

Passion, a commitment to quality and safety, and an emphasis on our diving family have kept Blue Marlin Dive at the forefront of the Indonesian diving industry for over 30 years.


Welcome to Blue Marlin Dive Tech:

Blue Marlin Dive Tech is Located East of Bali and off the North West corner of Lombok. The main headquarters for the operations is based on Gili Trawangan. Other shops are based on Gili Meno, Gili Air, Komodo, Senggigi, and with our latest dive shop opened in Lombok Kuta.

This first Technical IDC in December 2013 saw Blue Marlin Dive continue as the leading technical dive school in Indonesia, as pioneered since 1992 by Blue Marlin founder and owner, and accomplished TDI Instructor Trainer, Simon Liddiard. Five candidates participated in total, four of whom are already employed in the diving industry here with Simon’s diving companies. Since then we have had regular TDI Instructor courses with a 100% success rate and all candidates moving on to full time employment.

Blue Marlin Dive Tech is affiliated with Technical Diving International (TDI). We offer the full range of Nitrox, Mixed Gas and Closed Circuit Rebreather (CCR) courses as well as Technical Instructor courses to all levels to increase your knowledge and further your career.

We are a division of Blue Marlin Dive, which is dedicated to providing quality technical diver training, daily technical dive charters, and technical expeditions to all corners of Indonesia.

Our aim is not only to provide a conducive environment for training, but a facility where qualified technical divers can actually use their skills to dive the many wrecks and deep walls that the Gili islands and Indonesia have to offer. We feel a gap exists in the dive industry because many places offer technical diver training to divers, but few offer daily guided technical dives and technical live aboard expeditions.
