Dive Briefing
"A typical dive at Blue Water Wreck (MV Mabro) begins with entry from the dive boat, descending to the main formation at approximately 34 meters while orienting yourself and equalizing before exploring the remarkable Brunei underwater landscape. Once established on the main formation, divers should swim along the wreck structure or reef 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 24 and 31 meters where the highest concentration of reef fish species and photographic opportunities are abundant. Navigate along the wreck or reef edge watching for pelagic species in the surrounding water, and check the overhangs, holds, and ledges where moray eels, groupers, and larger reef fish shelter from the current. Brunei's wreck and reef environments require careful awareness of overhead environments and potential entanglement hazards when exploring interior sections. Monitor depth and NDL particularly near 36 meters on the deeper sites, and always maintain a conservative approach to dive planning given the distance to the nearest hyperbaric chamber in Miri, Malaysia. Scan the surrounding water for approaching pelagic species including eagle rays and barracuda that patrol the wreck 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."
