Me and my family, returned for another vacation in Thailand. This time as a wedding witnesses for our friends! It suited me perfect, because then I could leave my wife and son for a few days of diving! As I wrote in my last review, the live-aboard (oct 2009) was excellent.

We booked a 2 day diving trip, with an overnight stay in a bungalow on one of the... More

I used this company for a one-day trip to Similan Islands. My wife and I are avid divers and we dove in a dozen of different countries. We were deeply disappointed by this company, its service, staff and prices. First, the issue started with the staff. We went to the company location the eve of the trip. The owner was... More

A friend and I took the 4 night, 14 dive trip in February. From first impressions on arrival, and throughout the trip, we felt really looked after by the sds team. They were, fun, friendly, knowledgeable and safe, making for some really amazing memories, both above and below water. Our trip leader Tim was a breath of fresh air, and... More
