Koh Tao with Discovery Dive - Took a 4-day/8-dive package and visited different sites around Koh Tao. Excellent service provided by this dive centre from pick-up at hotel through transfer to the dive sites and actual diving all the way to back to base and hotel. Super guys; fun to dive with but ensuring safety at all times. They even managed to ensure that whale sharks made an appearance!!! Would recommend.

Fantastic. Highly recommend! - Highly recommend Discovery divers! I'm a new / nervous diver and took a refresher / Koh Tao trip on day 1 followed by Chumphon Pinnacle on Day 2. The instructors were extremely patient in teaching me the ropes again and were fantastic in their approach. Facilities / boat are nice, food is good and the diving, out of the world. Had the loveliest time and will return for more.

enjoy best diving with OT - my instructor eas OT. he is the best. American, indeed accurate english, explains everything with full patiance. with OT i could improve my diving skills, achieved to stay much in underswater. whoever in koh samui , diving with discovery and OT highly appreciated.

Best dive operation on Koh Samui - I recently took my family to Discovery Dive in Koh Samui, and it was an amazing experience! The introductory dive for beginners was fantastic; the instructors were welcoming and made me feel safe. My partner, a certified diver, loved exploring stunning dive sites, while our kids had a blast snorkeling and spotting colorful marine life. The staff was friendly and attentive, ensuring everyone had a great time. If you're looking for a family-friendly adventure in Koh Samui, I highly recommend Discovery Dive for an unforgettable underwater experience!

Great diving off Koh Tao! - Great team, safe and knowledgeable! Made for a memorable few days of diving! Very professional! The equipment was in good order and a brand new speedboat. All in all a Stirling service and experience!

Cheers to Zoey! - We have been diving all over the world and have enjoyed a lot of great dive masters. Zoey at DIscovery Divers in Koh Samui ranks with the best. She anticipated our needs and was super-helpful. We saw a lot and enjoyed ourselves tremendously. And lunch was amazing. Can't say that on too many 2-tank dives.

Highly recommended - We were staying in Koh Samui, they have a booth in front of the Amari resort. They picked us up at the hotel and we took the trip to Koh Tao comfortably on their own speed boats. The entire staff has a good vibe, especially OT, thank you for being our guide and for the photos you took of us 🤙

Diving Koh Samui - Our diving experience in Koh Samui unfortunately left a lot to be desired. The whole trip felt rushed, and there was a noticeable tension between the dive masters, which translated into a lack of clear communication. It was uncomfortable to see that the dive team didn’t seem to be on the same page, and as a result, we didn’t feel like we were given proper safety instructions or guidance. This lack of coordination left us uncertain at times, and certainly didn’t inspire confidence, especially when it came to safety protocols. On top of that, the equipment was in poor condition. The masks were moldy, and one of the tanks wasn’t properly secured, which made us feel uneasy while diving. We also had to hold onto a rope during the dive, which resulted in painful rashes on our hands that lasted for a week. While we understand the weather conditions were beyond anyone’s control, it seemed like the dive masters weren’t particularly mindful of the discomfort some guests were feeling. There was little consideration given to the fact that some of us might have been nervous or uneasy due to the weather, and that lack of empathy didn’t help ease our anxiety. To top it off, the refreshments were sparse—just coke on board—and there wasn’t enough food for everyone, which further added to the sense that the trip was poorly organized. It’s disappointing, as we were really looking forward to the experience, but unfortunately, it didn’t meet our expectations. The highlight of the trip, however, was spotting a green turtle despite the poor visibility underwater. It was a special moment, but it wasn’t enough to make up for the overall lack of organization.
