Two Fish Tech is Two Fish Divers’ technical diving arm and has been at the forefront of technical diving development in Indonesia since 2010. Operating from two of Indonesia’s prime diving locations – Amed in north-east Bali and Bunaken in North Sulawesi – we are dedicated to providing high quality PADI and TDI technical diver training courses, guided technical dives and technical expeditions.

Most of our technical diving courses are taught at our main base in Amed, Bali, which is both a PADI Tec Rec center and a TDI dive center. It’s a great place to get started with technical diving, whether you would like to learn to dive in twinsets or sidemount configuration. With easy access to a house reef, deep walls and one of Indonesia’s best-known shipwrecks nearby, the USS Liberty, we are spoilt for choice of dive sites. If you already hold initial tech diving qualifications, this is a good place to gain further experience.

A little further off the beaten track, our second tech diving location in Bunaken, North Sulawesi features Asia’s best wall dives. It’s quite simply perfect for already qualified technical divers who enjoy exploring deep reefs and working their way up the wall as they complete their decompression stops. Nearby, we have the Manado Wreck with intact propellers and rudders in only 40 meters – perfect for a technical dive.

/// Experienced Instructors

Tech instructor in bunakenYvonne has worked in the diving industry since 2010, starting out as a Divemaster and since 2011 as an instructor. Initially teaching and guiding in Scotland, her work has taken her to Egypt, Bali, Thailand and now Sulawesi. Originally trained in the warm waters around the Great Barrier Reef, Yvonne truly fell in love with the underwater world in the sea lochs of Scotland. In 2014 she moved back to warmer waters and plans on staying here for a while.

Deep walls and wrecks captured her imagination which led to initial tech diver training in the UK in 2011. Since then, Yvonne expanded her experience in Scotland’s Scapa Flow, the Red Sea, the Gulf of Thailand and Indonesia. She currently teaches both TDI and PADI TecRec to 55 and 50 meters respectively, in both backmount and sidemount configuration. In addition, Yvonne teaches Solo Diving. She is also a TDI Cave and Advanced Trimix (100 m) Diver as well as an Advanced Gas Blender.

/// Two Fish Tech Philosophy

Technical diving has had a reputation of being a niche for ‘big, bald guys’ who completed military-style training. That’s a thing of the past. We strongly believe that becoming a skilled technical diver has nothing to do with physical size or strength but instead with solid training and an emphasis on safety and professionalism. This is what makes a good Tech Diver. We want our customers to enjoy the challenges of their training and become a better and safer diver overall, whether they are diving to 20 or 60 meters.

/// What is TECH?

Broadly speaking, TECH diving can be grouped into Soft-Tech diving and Hard-Tech diving.

Soft-Tech

Soft-Tech 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-TECH courses/diving styles, they are for Open Water and Advanced divers who just want to dive a different way.

Hard-Tech

This is for more experienced divers who want to do more exploration-type and/or deeper diving. Its the Hard-Tech diving that is for those who want to do more exploration-type diving and/or deeper, 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!

/// Introduction to TECH

We run FREE Intro to TECH at our resorts in Bunaken and Lembeh where guests can try sidemount and twin sets.



Check out this video of a TECH INTRO that we ran at Atlantis Dive Center, Sanur, Bali. Over 2 days, we “introduced” more than 30divers to sidemount diving and Poseiden MK6 rebreathers. Great fun!!


/// TECH Diving in Indonesia

All our locations in Bunaken, Lembeh and Lembongan are great for tec diving.

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!

This area is mainly dived as muck diving, and photographers will find sidemount and rebreather diving appealing due to longer bottom times, more gas and great up-close encounters to marine life.

However, Lembeh also has some pinnacles and wrecks to explore. There are also large parts of Lembeh that are unexplored at the deeper depths, and we believe that there are also some undiscovered deep-water pinnacles and submerged islands that offer some fantastic diving.

We do not yet offer Tech diving in Lembongan
