/// 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.

Depth and decompression are not everything – it’s about skills and knowledge and many divers start their journey as advanced open water divers with a recreational Sidemount course or enjoy shallow dives on their rebreather. For some, that leads to deeper, more challenging dives and maybe even into overhead environments such as wrecks and caves. Our aim is to support technical divers on that journey.


PADI tec rec center tdi dive center

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.

Amed – Technical Diver Training and Guided Technical Dives
Most of our technical diving courses are taught at our main base in Amed, Bali, which is both a PADI TecRec 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 USAT 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.

Bunaken, Sulawesi – Deep Wall Exploration for Trained Technical Divers
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. We also offer the PADI sidemount specialty here.

/// Experienced Instructors

TDI Instructor Trainer Yvonne PressYvonne Press is a TDI Instructor Trainer, and currently the only female at that level in South-East Asia. Having worked full-time in the industry since 2010, diving has taken her from Scotland to Egypt, Bali, Thailand, Sulawesi and now back to Bali.

After becoming certified in Australia, the deep walls and wrecks of Scotland truly captured Yvonne’s 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 TDI instructors as well as both TDI/SDI and PADI TecRec divers to 60 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.

/// TECH Diving locations in Indonesia

Our locations in Amed, Bunaken and Lombok offer great tech diving opportunities.

North east Bali and the Amed / Tulamben area are becoming a bit of a hub for technical diving:

  • Great selection of training dive sites, including the USAT Liberty wreck at Tulamben
  • The dive sites are only 5 – 25 minutes away
  • Easy access to sloping walls and reefs that stretch well beyond recreational diving limits
  • Few divers explore below 30 meters here, giving you a good chance to have the dive site to yourself
  • Good opportunities to spot pelagic species including the elusive thresher shark
  • Warm water year-round with average temperatures around 28/29 degrees
  • Visibility tends to be around 15 meters + and even at depths beyond 40 meters, it is easy to keep team contact even without a torch

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!

In September and October 2017, Two Fish Tech is heading to Sekotong, South Lombok for two weeks of Sidemount and Solo Diver courses, Sidemount workshops and Sidemount Instructor courses. Add a day or two and head to nearby Belongas Bay to enjoy dives with Hammerhead sharks and Mobula rays! What’s more, if you bring a friend or two, each of you will receive a discount off your course price!


Why South Lombok? It’s one of those areas of Indonesia that’s almost undiscovered. No crowds, pristine waters, beautiful corals. Sekotong and the South Gilis offer great conditions for learning and lots to see on fun dives. You will need 2-3 days for a TDI or PADI Sidemount course and 1-2 days to become a Solo Diver. Workshops can be arranged flexibly depending on your needs. Lastly, the TDI Sidemount Instructor course take 3-4 days.


Once the ‘hard’ course work is done and for a bit of excitement, we will head to The Magnet, Belongas Bay, to enjoy diving with pelagic species including Hammerhead sharks and Mobula rays.

In 2017, we will be in South Lombok from 21-30 September and 21-30 October. Courses can be arranged flexibly within those dates. Contact us for more information.

/// Intro to Tech Diving

We run FREE TECH TASTERS at our resorts and dive centers in Amed and Bunaken 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!!
