POSTS STORIES REELS TAGGED

The coffee might have stopped working 3 days ago but we persevered, grew exponentially as educators, and even had some fun along the way 😎
Massive congrats to the Playa del Carmen Global Underwater Explorers Fundamentals Instructor Candidates! I’ll gladly be back for another one sometime next year.

We’ve had a nice chill holiday here in Sardinia. Spent some time by the water, relaxed with a book, explored and documented some cave… you know, typical vacation stuff.

It’s been a great month here with some amazing people and some epic dives. I’ve definitely got a lot more grey in my beard now, but along with it a few good stories and plenty of photos to share.

Ok, that’s most of it. Now clothes and all the camera gear 🤦🏻‍♂️

Looking forward to an epic 3 weeks back in Sardinia teaching @guehq cave 2 and some exploration with @phreatic_organization!

That’s a wrap on another successful @guehq cave 1 course, and I could not be more proud of these two guys! Perfect examples of how patience, hard work and laser focus pays off. Thanks so much for the opportunity to work with you both!

GUE CAVE 2️⃣ ✅
An accumulation of everything I’ve learnt.
But more importantly - more time in the cave = more time with friends. More cave imagery and dive reflections coming soon 🫧🤍
