Cave and overhead training is not to be undertaken lightly, nor seen as a natural progression or some higher level diving badge or award. Cave diving is also not for thrill seekers and adrenaline junkies. We suggest you watch the video here….And then get in touch with us for a coffee and chat about the way forward.

Our cave experience encompasses Irish and UK caves, France, Italy, Mexico, Florida, Philippines, Spain and more. We are experienced in open circuit from Mexico style sidemount to full CCR. We can train you to expedition level including mixed gas.

The pathway will not be fast, there will be no shortcuts, but we will be delighted to dive any cave with you when done!
