Fun Diving for specialty and Tech divers...

    Already Certified? Fun Dive With Us!

    Big Blue Tech has been fun diving Koh Tao for many years, and our experienced team can guide you around the Koh Tao dive sites.

    With the option for refreshers and shake down dives depending on experience and certification level, we can take you from sandy bays out to the pinnacles and wrecks Koh Tao is famous for.

    Backmount, Sidemount, Twinset or CCR we can cater for you all and with our own boat the chances to stay longer on the deeper sites is always an option.


    Diving with Big Blue Tech

    Were you told to gain experience at each level before moving on? You should have been, if you were then you've come to the right place! We want you to enjoy your hard earned certifications, whether they're considered "Recreation" or "Technical", building on them before moving onto the next course can be just as rewarding as completing them in the first place.

    If you want to get back into that wreck or hit the deco out on the deeper sites then take a look at your options below and get in touch with us and lets go diving!
