We know, 40 metres is not enough. Some of the best wrecks and most amazing sites are below the recreational range, and you need technical diving gear as well as knowledge and skills to reach them.
The Extended Range program qualifies you to dive to 45 metres using nitrox mixes up to 100% oxygen for accelerated decompression times. You learn to plan and execute up to 25 minutes of decompression using one stage decompression gas. The programme can only be completed wearing specialized technical diving equipment. The training can be conducted using air or limited Trimix.
Koh Tao Tech Divers offers rental gear as part of the course, so you don't have to worry about getting all of the specialised equipment at first!
