Technical Diving in Manado

Gideon TechOdyssea Divers at Cocotinos Manado Boutique Dive Resort & Spa  is the first diving facility in Manado to offer technical diving and training. You will find sheer drops to hundreds of meters at the amazing walls of Bunaken National Park and Bangka islands. Furthermore, there are many undiscovered sites for those looking for more challenging technical and exploratory diving. The resort also offers technical dive equipment and training, with dive crew and boats experienced with technical divers and their equipment.

The walls at the Bunaken National Park drop to over 800 meters, and are largely unexplored, with only rumours of big fish living beyond the recreational diving limits. The Bangka island walls drop to over 70 meters, and have deep reefs that go all the way down to the sandy bottom. The wrecks in the Lembeh Straits are also accessible a few hours’ drive away. With Manado’s traditionally calm waters and amazing visibility, this is the perfect location to experience technical diving at its best.

Come and explore the undiscovered depths of Manado and be one of the first to experience a new frontier in the blue waters of North Sulawesi.

The Odyssea Divers’ crew has experience dealing with technical divers. These include dealing with scooters, mixed gas and stage-bottle handling. All the equipment that is available for rent includes 20 double-tank setups, with another 20 stage tanks available for decompression gases. Helium and Oxygen are available for use and will be made available when required.

Technical Diving Courses

Odyssea Divers offers GUE Courses organized by Living Seas in Singapore and conducted by GUE Instructors Gideon Liew and Leon Boey. Please email us if you need more information on the courses below.

GUE Fundamentals

The GUE Fundamentals course is designed to cultivate the essential skills required by all sound diving practice, irrespective of level or environment. A prerequisite for the rest of the GUE classes, save Recreational Diver level 1 course, GUE Fundamentals performs a three-fold function.

1. It provides the recreational diver, who does not desire further diver training, with an opportunity to advance basic diving skills, thereby developing more comfort, confidence, and competence in the water.
2. It provides the diver with aspirations of more advanced diver training with the tools that will contribute to a greater likelihood of success.
3. It provides non-GUE trained divers with a gateway to GUE training.

GUE Technical Diver Level 1

GUE’s Technical Diver Level 1 (Tech 1) course is structured to prepare divers for the rigors of technical diving and to familiarize them with the use of different breathing and decompression mixtures. Tech 1 training focuses on expanding the fundamental skills learned in the GUE Fundamentals course (or elsewhere), and is designed to cultivate, integrate, and expand the essential skills required for safe technical diving. This will include problem identification and resolution, and building the capacity for progressively more challenging diving. In this class, students will be trained in: a) the use of double tanks/cylinders and in the potential failure problems associated with them; b) the use of Nitrox for accelerated and general decompression strategies; c) the use of Helium to minimize narcosis; and d) the applications of single decompression stage diving, with respect to decompression procedures.

The class will focus on Nitrox and Trimix as breathing gases for dives down to 160 feet/48 meters, and provides an excellent foundation on which divers can build their technical diving experience and prepare for GUE’s Technical Diver 2 course (Tech 2).
