Jandri Scuba Dive Lembeh is a locally owned dive operator in Bitung, North Sulawesi, running daily guided muck diving in the Lembeh Strait.

Local guides lead boat dives on the strait's black sand slopes, including Nudi Falls and Hairball. In Lembeh that matters: the diving is about finding camouflaged animals such as frogfish, mimic octopus and rare nudibranchs, and guides who dive these slopes every day find what visitors would swim past.
