Dive Briefing

"A typical dive at Dolphin Reef (Koh Tang) begins with entry from the dive boat, descending to the main formation at approximately 16 meters while orienting yourself and equalizing before exploring the remarkable Cambodian underwater landscape. Once established on the main formation, divers should swim along the reef structure or wreck exploring diverse habitats, moving between coral encrustations, swim-through sections, and sandy areas while maintaining excellent buoyancy control to protect the marine life colonising the structure below. The most productive depth zone is between 6 and 17 meters where the highest concentration of reef fish species and photographic opportunities are abundant. Navigate along the reef or wreck edge watching for pelagic species in the surrounding water, and check the overhangs, crevices, and ledges where moray eels, groupers, and larger reef fish shelter from the current. Cambodia's reef and wreck environments require careful awareness of marine life hazards and potential entanglement when exploring interior sections. Monitor depth and NDL particularly near 22 meters on the deeper sites, and always maintain a conservative approach to dive planning given the distance to the nearest hyperbaric facilities. Scan the surrounding water for approaching pelagic species including eagle rays and barracuda that patrol the reef edges. Conclude the dive with a slow ascent and a generous safety stop at 5 meters, deploying your DSMB before surfacing and signaling the dive boat for pickup."
