Open Water Course Koh Tao, Diving certification with Phoenix Divers

Open Water Dive Certification

Myself and a friend came to Koh Tao to get open water certified and can’t recommend Phoenix divers enough! Our diving instructor was very patient and kind, made us feel completely at ease and ensured we had a great diving experience on Koh Tao. We left the course feeling like confident divers and excited to continue scuba diving. Highly recommended. From snugebutton
