Arno’s Underwater Reef: deep current-facing Raja Ampat dive.
ScubaFreediveBoat EntryAdvanced

Use a local Raja Ampat operator that can place you close to the drop-off and judge the current before the first descent.
Boat drop-off dive for experienced divers; keep close to the reef edge and plan around the current rather than wide swimming.
About Arno’s Underwater Reef
Arno’s Underwater Reef is a boat-access Raja Ampat drop-off on the Mansuar/Kri side, built around a deep overhang, a fast-moving reef edge, and a shallow soft-coral finish. It suits experienced divers who want to stay close to the profile, work the current with the guide, and pick through reef fish, nudibranchs, wobbegong, and the occasional manta rather than wandering wide across open water.
