Paul was fantastic! He has a great knowledge of the local dive sites, was very professional and guided the dives to our ability. We were AOW divers who had not dived for several years. We felt very relaxed with Paul. He exceeded our expectations and even managed to retrieve a fin we lost during one of our dives. We would... More

We went to Koh Samui to celebrate hubby's birthday as well as a belated anniversary. Wanting to try different experiences, hubby went through the various websites to see what we could do in Samui and came across CSI Samui. He went ahead to contact Paul, the owner, and made a deposit to secure our diving date. Paul came to meet... More

Paul kindly met us at our hotel a couple of days before our dive, and went over a few details of what to expect.... More

I will come again. Paul is very professional and friendly, he made sure everything went well, and made a lot of efforts to show me interesting things. The equipment is excellent and near new.

We went out with a lady named pat who explained everything to us and was a good dive master. She showed us... More

He's got a very fun big personality which makes the diving easy and relaxed. Very concerned with safety and the... More

This was my third time diving around Samui, and first time with CSI. What a wonderful time! Paul, the owner of CSI, a great guy who's an extremely responsible expert to make your diving experience safe, but also a very easy going and understanding to give you time and space you need in order to explore the local underwater world....

Thanks again to Paul and Christine for all the help and professional advice in getting me through the PADI OPEN WATER DIVER qualification.

Now I have the qualification I cant wait to come back and see some more of wonderful Koh Samui and beyond. I... More
