Hydronauts Diving

Founded in 2017 by world renowned technical diving instructor Erik Brown, Hydronauts follows the philosophy that skills which work for a diver at 100 meters will work equally well at 10. Taking a holistic approach to diving means that we understand that the best equipment, combined with a commitment to excellent buoyancy control and rigorous dive planning will result in the most competent and confident divers possible. This has been borne out in our graduates, who both rave about their training and are raved about by other divers!
As a RAID dive center, we are able to provide excellent instruction for all levels of training from Try Dives to Technical Instructor Development courses.

Hydronauts is the only dive center on Koh Tao to teach with the backplate & wing style BCD and long hose configuration from the get go. In addition to the BCD providing the most streamlined and comfortable dive experience, safety is enhanced by the long hose’s rapid deployment in out of gas situations. We use the XDeep Zeos Dive Center Edition BCD, which can be adjusted for a perfect fit to any body type in minutes and features integrated weights for added comfort. Our Aquatec regulators are the only over balanced shop regulators on the island and are the same design as used for depth record setting dives! For added power and comfort, we provide our customers with neutrally buoyant jet fins from Aquatec and XDeep. All of our divers are issued dive computers as standard so as to be as independent as possible.

Our attention to detail means that diving with Hydronauts is a truly unique experience!
