The Tech 40 course lays the foundation for your technical diving career as you will be able to dive further, deeper and longer. Introduction begins with primary safety skills.

Tech diving can be a challenging, stimulating & exciting concept. Tech courses will teach you to dive deeper, for longer, using multiple tanks & mixed gasses. We offer training that will enable you to access more challenging environments such as wrecks, caverns & caves. Courses we offer include Tech Deep, Trimix 65, Trimix 90, Wreck Speciality & Advanced Wreck Speciality. Davy Jones Locker are also one of the few dive schools on Koh Tao which can offer Closed Circuit Rebreather (CCR) training.

Tech and wreck dive sites are easily accessible from Koh Tao. Cave diving takes place on the mainland. Song Hong and Khao Sok are both popular spots when we undertake expeditions.
