What Our Customers Say
★★★★★
Skye Stoury
"Took my open water course through OK on Koh Lanta and it was amazing! I was paired with a great instructor and the four dives we did were stunning. All of the dive masters were a lot of fun and checked in with us throughout the dives. Would dive with them again!"
★★★★★
Bjørn Christopher Wang
"Good trip with good people. Also lucky today with visibility.
They use a speedboat which is perfect when you do remote working. Also it makes it easier to get to know the other divers since it's a smaller boat compared to other companies.
They also use DIN on all equipment, which I really like, and also have sidemount rental if you're certified."
★★★★★
Ben Iten
"What a great start to my diving career! Did my OWD certification here, very thorough and personal training, well organized, competent people. Recommend! Kudos to the Swede, he knows what he’s doing."
