Advanced wreck diving

Extended Range Wreck (Advanced Wreck)

Who's Afraid of Overhead?

You see the open rooms and hulls, corridors that plunge into the depths, and want to go in. After this course you'll know what you need to take into account for that to happen safely!

The Advanced Wreck Diving programme allows limited penetration into the wreck overhead environment. You will learn overhead buoyancy and propulsion skills along with using a line and lights to your advantage. The course can be completed wearing a single cylinder with either a pony cylinder or H/Y valve, sidemount or a technical total diving system.

Koh Tao Tech Divers has all the necessary equipment you will need, but it is recommended to use your own gear as much as possible.
