Tec Diving Guidelines

Trawangan Dive is dedicated to providing quality technical diver training and guided daily technical dive trips. 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 deep walls, pinnacles and wrecks the Gili Islands and Indonesia have to offer.

We feel a gap exists in the dive industry, as many dive operations offer technical training to divers, but few offer daily-guided technical dives and TDI Technical Diving Courses. Our aim is to try and fill this industry gap.

By taking the technical diving courses you will not only learn a great deal, but also be challenged and by the end of the course you will be a much more knowledgeable, capable and accomplished diver.

The co-founder of Trawangan Dive, Simon Liddiard has been living and diving the waters around the Gili Islands and other parts of Indonesia since 1990. He is a PADI Course Director and has been an Instructor since 1986. Simon also holds the following TDI and IANTD Certifications: Nitrox Instructor Trainer; Technical Wreck Diver Instructor; Normoxic Trimix Instructor; Trimix Instructor Trainer; Inspiration, Evolution and JJ CCR Trimix Instructor, and is a member of the IANTD Board of Advisers.
