TECHNICAL DIVER TRAINING, TECHNICAL DIVING, TECHNICAL EXPEDITIONS


/// Two Fish Divers joins with Blue Label Diving

In Feb 2013, Two Fish Divers and Blue Label Diving created a joint venture, Blue Label Diving Indonesia (BLDI), that is dedicated to providing quality TECHNICAL DIVER TRAINING, DAILY TECHNICAL DIVING, as well as TECHNICAL EXPEDITIONS to all corners of Indonesia.

Through BLDI, PADI & TDI courses and Technical diving and Technical explorations are available in each of the locations of Two Fish Divers. As of April 2013, this has only been established in Bunaken, and Blue Label Diving Bunaken is the first and only PADI Tec Center and TDI Center in North Sulawesi.

With the close proximity to Lembeh, Bunaken can support TEC diving & courses in both Bunaken & Lembeh. We hope to have Blue Label Diving established in Lembongan by June 2013, this will let our guests have real close-up encounters with the manta’s and mola-mola’s with no bubbles on a rebreather!

/// Who is Blue Label Diving?

Tec diving with Blue Label DivingBlue Label Diving is a premier PADI/TDI facility for TEC Courses and diving, and has operations in Thailand, Maldives and Australia. Blue Label Diving is owned by Ben Reymenants, renowned cave diver/explorer and record-holder for deep diving on rebreathers, and his wife Simone Reymenants. They run the full range of TEC courses including Sidemount Diving, Solo Diving, Nitrox/Advanced Nitrox and Decompression Diving, Rebreather Diving, Trimix Diving, and Cave Diving.

/// What is our experience?

/// Why TEC Diving around Bunaken?

There are some very good reasons to Tec dive around Bunaken:

  • The dive sites are only 10mins away
  • Walls around Bunaken drop to more than 600m, and visibility is 25m even at 75m+ depth.
  • The water temperature around Bunaken is 29C making for fantastic reef life – Bunaken Island is considered to be one of the most diverse marine environments on the planet.
  • The larger animals such as sharks & mantas like colder water. There are occasional sightings of these animals by our guests, so they are here, however they are found at the deeper levels 55-70m where the water is colder (25C).
  • Coelecanth fish at 90-120m, exploration trips are run regularly
  • We believe that there are also some undiscovered deep-water pinnacles and submerged islands which may offer some fantastic diving, and we will be doing some exploration of the area to find them. We are extremely excited about this as no one has ever done this type of exploration in the area before!



/// What is Technical Diving?

Broadly speaking, TEC diving can be grouped into Soft-TEC diving and Hard-TEC diving. Soft-TEC diving is only aimed at recreational divers and includes:

  • Sidemount Diving – having a tank on each side is a lot more stream-lined and comfortable, and the extra gas is ideal for photographers wanting to stay longer as well as those gas-guzzlers. Its also good for those with bad backs because the weight is distributed more evenly and you can easily put-on/take-off your gear in the water
  • Solo Diving – learn how to be self-reliant, perfect for those photographers who like to sit in one place for ages. It can also be combined with Sidemount Diving to give the extra gas!
  • Nitrox Diving – ideal for staying for longer at that ship-wreck, but is also used for added safety and less tiredness
  • Rebreather Diving – fish and underwater life are not scared away when you have no bubbles, so you can get up closer with that camera!

You do not need to be experienced divers for these soft-TEC courses/diving styles, they are for Open Water and Advanced divers who just want to dive a different way.

Its the hard-TEC diving that is for those who want to do more exploration-type diving, and includes:

  • Advanced Nitrox and Decompression Diving – using open circuit or rebreathers, this type of diving takes you beyond the recreational limits to 55/60m
  • Trimix Diving – using open circuit or rebreathers, you can add an extra gas to go deeper still, beyond the 75m level
  • Wreck and Cave Diving – using open circuit or rebreathers, with or without trimix, diving in overhead environments where few have been before – a bit like exploring mount everest!

/// Coelecanth Diving Expeditions



The Coelacanth is a prehistoric creature that thrived in the oceans over 400 million years ago. Thought to be long extinct until rediscovered alive in 1938.

A deep water living ‘Dino-Fish’ that lives in waters between 90-150m, it has been found in only two areas of the world, Bunaken Island being one of these areas.

The Bunaken Coelecanth has only been filmed using ROV, so imagine yourself part of a team of explorers to find and dive with this amazing fish!

PADI Tec Diving Courses

/// Try TEC

For those who are interested in tec diving and finding out a little more about using a different configuration of equipment, added tanks and of course, looking very cool, then Discover Tec is a good way to do so.

You will learn the basic setup of twin banded cylinders that would be back mounted as well as how to rig up and carry a stage cylinder on the side.

You will also be introduced to some of the tec skills learnt in the the first tec level course, the PADI Tec 40. DANGER, PROCEED WITH CAUTION, TEC DIVING IS ADDICTIVE!

DISCOVER TEC Prerequisite: Open water diver with 10 dives



/// Sidemount Courses

Find a new and different way to configure your cylinders in the PADI Sidemount Diver course. Sidemount diving offers:

  • an alternative way to streamline in the water
  • easier equipment transportation when topside
  • reduced lower back strain
  • redundant gas supply
  • ability to monitor all equipment because it’s in front of you
  • increased gas supply for longer dives

PADI Sidemount Prerequisite: PADI Open water diver and at least 15 years old.

Tec Sidemount offers the same benefits as the PADI Sidemount Diver course but gives you the opportunity to dive with up to four cylinders for extended dive times and depths.

The Tec Sidemount Diver course is a great way to start with technical diving because the skills you learn in this course will train you to handle multiple cylinders on a single dive.

You can combine what you learn in the Tec Sidemount Diver course with other open-circuit tec courses that you take, or certifications you’ve already earned, to take advantage of sidemount’s cylinder configuration and handling.

PADI TEC Sidemount Prerequisites:

  • Be a PADI Advanced Open Water Diver
  • Have logged 30 or more dives
  • Be at least 18 years old
  • Certification as PADI Enriched Air Diver is recommended

/// Open Circuit TEC Courses

The Tec 40 is the entry point into the technical diving, the transition from recreational diving. During the course you will be using the full technical diving equipment configuration of twin banded tanks and carrying up to one stage tank to a maximum of 40 meters.

During this course you will learn to plan dives using up to EANx50 (advanced nitrox) with decompression software to conduct dives with up to 10min of decompression.

TEC 40 Prerequisites:

  • Be a PADI Advanced Open Water Diver (or hold a qualifying certification from another organization)
  • Be a PADI Enriched Air Diver (or hold a qualifying certification from another organization)
