Are you ready to explore overhead environments?


Do you want to explore deeper depths, and experience longer dives? When you feel it is time for new challenges, technical diving is the logical progression for your growth as a diver. Our technical diving courses increase your knowledge and  skills.


The IANTD Intro to Cave course is the perfect way to develop the fundamentals of cave diving. The Full Cave and Technical Cave courses will expand your limits and teach you the necessary procedures to conduct longer and deeper overhead dives.


Diving with Sidemount configuration in different environments requires training and knowledge of the different configurations. It is minimalistic and provides the diver with simple and effective procedures, and therefore is considered the most versatile, streamlined and flexible way to dive.


If you are an advanced diver, who is ready to take the next step and expand your horizons, specialty courses will introduce different environments for you to discover. Become an Deep Diver, Cavern diver, Wreck Diver, DPV Diver, or Nitrox Diver.
