/// Open Circuit Diving

Open circuit diving uses the full technical diving equipment configuration of twin banded tanks with side-slung stage tanks. The gas supplied during Open-Circuit scuba is not recycled at all. When a diver breathes out, the exhalation goes out to the surrounding water instead of being recirculated.

Open Circuit Tec Courses

There are many course options from both PADI and TDI training agencies , and it depends on your objectives.

  1. entry point courses into the technical diving where you make the transition from recreational diving
  2. subsequent courses that allow you to use any mixture of Nitrox and even 100% oxygen, to plan and conduct dives requiring some accelerated decompression with multiple gas switches during a dive to 45 meters
  3. additional courses that teach you more accurate planning and near perfect diving skills in order to dive to 50/55m.

At both Bunaken & Lembeh, we have TEC Instructors that can buddy you right up to extended trimix dives to 100m and beyond.
