PADI’s DSAT Tec Deep course enables you to undertake deep decompression dives to a depth of 50 metres.

During this course you will be trained to dive with a twin set and stage/deco cylinders, using up to 100% O2 enriched air blends to accelerate your decompression schedule, or enhance the safety of your dive.

We have a variety of wrecks & deep dive sites around Koh Tao, which makes this an ideal location to take your DSAT Tec Deep course. This is a challenging course, but if you’re the right kind of person deep technical diving is an exhilarating experience. By taking your DSAT Tec training with Davy Jones Locker you’ll get the opportunity to make deep wreck dives around Koh Tao, plus you will gain the experience to work & dive on tech liveaboards further afield.
