Guraidhoo Kandu

Guraidhoo is South Malé's textbook kandu dive and a protected area for good reason. On a pushing tide, divers hook into the outer corners and watch gray reef sharks hold effortless station in the flow while eagle rays and the odd Napoleon wrasse slide past. Release the hook and the channel does the rest, funneling you over a saddle of coral heads toward the lagoon as snapper and fusiliers stream alongside. Surge and speed vary with the moon; the briefing matters, and so does staying with the group in mid-channel blue.

您此行的高光时刻: Hooked-in shark watching; a fast, clean drift into the lagoon

地形地貌: Channel walls and a coral-strewn saddle between two islands, dropping to the open sea

水流: A working channel: incoming tides give clear water and shark action, outgoing tides get green and are usually avoided.

危险因素: Strong tidal current, mid-channel blue-water sections, and boat pickups in open water.

保育: Protected marine area; fishing is banned in the channel.

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）。
