One of the best diving experience I have ever had. From the beginning when I enter the shop Brenda helped me with everything. I was not sure what dive spots I should go and Brenda really knows the place, explained everything and gave me recommendations. Their equipment is pretty new so I felt totally safe. The diving itself was stunning. I did diving Richelieu rock. It is a really lovely spot full of corals and a loooot of fish. I can not forget about amazing service. Everything went totally smooth from the transport, delicious food (breakfast, lunch, snacks, dinner) and so lovely staff on the boat who took care of everything. I did not have to do anything. Just be on the huge boat and enjoy the moment. I just regret that I did not have more days. It is possible to stay on the boat overnight and dive more days. It could be an amazing experience. I hope next time :) Thank you Brenda! :)

Thanks to B, the three of us had an unforgettable liveaboard experience! The warm and friendly atmosphere made us focus on diving at Richeillous Rock. B was incredibly helpful and sensible in assisting us with selecting our masks, wetsuits, and fins. The gear was in excellent condition, and our guide Ping was amazing too. Thanks to him, we saw rare local fish as well as countless other fish. I can't wait to revisit next year !!

5 Star Review. 2, days trips completed with Pirate Divers. Brenda was super quick to reply to our initial emails and everything was handled smoothly for there. Including an excellent recommendation of a local B&B. All equipment was in excellent condition. Can’t thank Brenda and our private guide Stefan enough for making it an unforgettable couple of days.

My partner and I were looking to squeeze in one more day dive trip before the end of our holiday, but were a bit overwhelmed by the sheer amount of dive shops and providers in Khao Lak. Well, that search ended the second I met Brenda. Such an awesome person and well connected with the diving community in Khao Lak. We felt so taken care of and she was able to accommodate a very last minute day trip to the Surin Islands, which we both enjoyed immensely. Her gear is immaculate as well, and makes sure it all fits you properly before leaving the shop. She personally inspects and cleans everything before and after every rental, so you know you won't have any problems once on the boat. She made sure she were picked up on time, was available on both phone and WhatsApp throughout for anything we might need to ask or double check. Very good prices too, and it's definitely value for your money. Looking forward to coming here again on our next trip to Khao Lak!

I can’t rate Brenda at Pirate divers highly enough! From the moment you meet her you feel you are in good hands. She was honest and open telling us the different options we had for our day trip and was great at advising us. She knows all the operators in the area and has dived all the sites. So she really knows what she is talking about. Her rental equipment is all in great condition and she was available in person and via WhatsApp to answer any questions we had. You can tell she really cares about her clients and wants them to have the best time! Thanks Brenda! We will be back soon

We booked a Similan 5D5N liveaboard through Pirate Divers and it was one of the most organised dive trips we've been on! Brenda was able to find a liveaboard that fit our schedule and had the course we wanted to do. Booking through her shop meant we used her equipment instead of the shop that runs the liveaboard. Her equipment was really well maintained and new. The regulator breathed superbly and I felt safe to rely on it throughout the entire liveaboard. The BCD was new and had no velcro straps that were falling off like you would get with some older rentals. Highly recommend!

Amazing experience and I 100% recommend this dive shop. Brenda, the owner is super experienced and very kind. She will make sure your equipment fits you perfectly before sending you off on one of the best dives of your life. Everything went well from hotel pick-up, boat trip, dives with experienced and safe instructors, intervals with good food and easy delivery home. Thanks again Brenda, you are a star and good luck! 🙌
