Jina Pass

Jina is Kinasi's understudy and, on its day, the better dive. The southern pass moves less water, so its walls hold delicate growth the main channel cannot keep — fans, soft coral tufts, sponge in quantity — while still pulling in channel traffic: snapper walls, trevally raids, turtles, and rays in the chutes. Groups drift the wall on the making tide, tucking into undercuts to let the flow slide past. Because most operators default to Kinasi, Jina often comes up empty of other divers, and guides save it for the tides when it runs clean and green-free.

您此行的高光时刻: Quieter channel drift with better-preserved wall growth

地形地貌: Channel walls with coral heads, undercuts, and sand chutes

水流: A second, quieter gate into the bay system; tide-timed like Kinasi but usually gentler.

危险因素: Tidal current and surge at the seaward mouth.

许可证与规定: Marine-park daily fee applies.

保育: Marine-park rules apply; the soft growth on these walls is the reason to keep trim tight.

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）。
