Shir Meir2025-03-23 Had a trial dive today with William and Billy, and had the best time ever. They are both so patient, professional, and have a huge passion for the ocean. The company has its own boat, so you're more likely to be diving on your own, without many other divers around. I couldn't recommend them more. florian hoffmann2025-03-22 Hey Ho Ich habe meinen Tauchschein dort erweitert und es war super !! Ich bin rein gekommen und fühlte mich sofort wohl und aufgenommen Mein neuer buddy und auch mein instructor dewesh ist ein Nice Guy Erklärt ausführlich auch mal langsam Unter Wasser fühlte ich mich hinter guten flossen geführt Ein herzlichen Dank ich komme auf jeden Fall wieder Mio Horikawa2025-03-19 I did a try dive (1day) today and it was an amazing experience. It was my first time diving and I was a bit nervous, but my instructors Erik and Billy took very good care of me and even calmed me down very professionally when I was panicking. Even the land staffs were very friendly and helpful. The corals and fishes were so amazingly beautiful, needless to say. Highly recommended! Thomas Wall2025-03-18 Highly recommend this dive shop if you're in Sairee Beach. Completed my open water course over 3 days with Matt as my instructor who was a great teacher and dive buddy. The two pools for skills were nice and the boat for diving felt safe. Small groups and not rushed at any point. Thank you to all at Seashell Divers Aaron yates2025-03-16 I am very happy that I chose to get my open water diving certificate with seashell. Devesh was a fantastic teacher who helped me with anything I needed to get me ready for my first dive and last dives, couldn’t recommend them more. Tyler Parkes2025-03-14 My Diving instructor was Devesh and I felt at ease throughout the whole process. I had a great time Diving and he is a great teacher Jan2025-03-13 I had a really cool dive with Devesh. He is a very good Instructor. Always again Andrei Busk2025-03-12 My wife and I had a very nice time fun-diving with Seashell during our 5 day stay at their hotel. All of the staff were kind, interested and professional throughout or stay. They went above and beyond to make our experience as rewarding as possible and made sure that both my wife and I got to see the different dive sites of Koh Tao even if it meant changing up the original plans to make it happen - That was greatly appreciated! I had the pleasure of diving with 3 different dive masters, Lydia, Shaun and Devesh (apologies if I didn’t get the names completely right), and all 3 of them did a great job on safety and entertainment. Last dive was with Devesh who made it fun and memorable in spite of probably the worst conditions of this trip. Big kudos for that 🤙🏼 (On a side note that is worth mentioning, the price for a package of 6 or more fun dives is 900 per dive. I’ve been diving with other schools where they charge 700 per dive, which of course adds up in the long run. On the plus side Seashell always provides you with a dive computer, where I would have to pay 500 to borrow one per day in the other places. I guess that the difference in price varies from place to place. Still happy to have been diving with Seashell though.) 😊 Thanks again for a great experience - Hope to see you again another time. 🤗 Lucy Pomeroy2025-03-10 I had the best time completing the one day diving course with our instructor Davesh. He was patient, funny and a fantastic teacher. Our whole group successfully completed two dives while having the best time. I would would highly recommend both seashells diving who were efficient and flexible, and davesh to anyone beginning their diving training !! Maike Schmidt2025-03-09 Ich hatte 12 fantastische Tauchgänge mit dieser Divebase! Absoluter Vorteil im Vergleich zu manchen anderen Anbietern auf der Insel: die kleinen Gruppen. Wir waren immer nur 8 - 12 Personen auf dem Tauchboot und getaucht wurde in sehr kleinen Gruppen, damit jeder auf seinem individuellen Level tauchen konnte. Die liebe Lydia kann ich als Guide nur empfehlen, mit ihr hab ich mich immer sicher gefühlt! Auch der Rest des Teams ist super nett und bemüht. Tauchausrüstung und Boot waren gepflegt, hat einmal etwas nicht gepasst, wurde es sofort ausgetauscht. Ich kann die Seashelldivers nur wärmstens empfehlen!
