c_171_171_16777215_00_images_ariwill.jpgBlue Marlin Tech is a division of Blue Marlin Dive, which is dedicated to providing quality technical diver training, daily technical dive charters, as well as 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 as many places offer technical training to divers but few offer daily guided technical dives and technical live aboard expeditions. Our aim is to try and fill this gap in the industry.

Although we recommend all technical fun divers use their own equipment, we realise there are times that it may not be practical for you to bring everything with you. We have a wide variety of necessary tech equipment available (primaily Apeks and OMS) and we also have a huge variety of tanks available, including 22lt isolation manifold twins, 25 lt. isolation manifold twins, single 11lt, 8lt, 5ltr,4lt and 3lt decompression tanks. All our boats are equipped with emergency oxygen, mobile hand phones and an extra supply of deco gas. We even have buddy evolution and evolution + closed circuit rebreathers for courses, rental and retail as well as a generous supply of Sofnolime grade 797 for our rebreather clients.

Dive Guidelines


Outside of training activities, diving will be supervised in water (or from surface where deemed appropriate) by qualified Blue Marlin staff. Diving will take place at sites appropriate for the experience levels and certifications of the individuals involved. All decompression diving activities will be backed up by dedicated boat cover equipped with surface oxygen, additional decompression gases as required, and with mobile phones.

Fun Diving


The 23+ spots visited by recreational divers have been joined in the last few years by at least the same number of dive sites in deeper water, the vast majority of them within a fifteen minutes boat ride off the beach.  You are welcome to join our daily recreational sites for decompression diving or our dedicated technical dive boat that visits tech-only locations.

Dive Sites


The Gilis are blessed with beautiful technical diving because the ocean around us drops off to over 1200m and with the steady currents bring a variety of marine life including sharks, rays, turtles and pelagic fish. Around the 40m range the islands shelf drops off and we have stunning walls starting at 40m - 100m, which because of their depth are only visited by technical divers and are therefore in pristine condition. If you enjoy wreck diving, we have an intact Japanese Submarine Chaser from world war II lying in approximately 45m.
