False Entrance

From the surface the reef rim seems to open into the lagoon here, but the gap is a dead end, and the misdirection gave the site its name. Underwater the false gateway is the good part: surge-carved canyons and swim-throughs braid through the rim, spilling divers out onto a wall that drops with the usual Osprey indifference to scale. Sharks patrol the seam between reef and ocean, dogtooth tuna hang in the current shadow, and on calm days the shallow cuts fill with shafted light that makes every diver look like a movie still.

您此行的高光时刻: Canyon swim-throughs, patrolling sharks on the rim, dramatic light in the shallow cuts

地形地貌: A deceptive notch in Osprey Reef's rim with canyons, cuts, and the outer wall

水流: Flow along the rim varies with tide; crews pick the drift direction on the day.

危险因素: Surge in the cuts and depth on the outer wall; not a site for loose buoyancy.

高氧（Nitrox）: 在此值得使用——各潜点深度落在富氧空气（nitrox）能有效延长免减压时间的区间（前提是持有相应认证）。
