Isdhoo is one of the three outer channels liveaboards log when giving Laamu two to three days on a southern-atolls itinerary. Wannadive puts the average depth at 20 m and the maximum at 40 m, with current at one to two knots and visibility of 10 to 30 m — a deep, flowing channel rated for Advanced Open Water divers.
Where it is and how deep
2.1348° N, 73.5882° EPublished position for this site.
The dive
The published profile sets the shape of the dive: an average depth of 20 m against a 40 m maximum, in current that typically runs at one to two knots, dived as a drift and planned around the tide. Wannadive rates the experience needed at CMAS two-star or Advanced Open Water and files the site as a liveaboard dive rather than a resort day trip.
Visibility is listed at 10 to 30 m. There is less published detail here than for Fushi Kandu or Maabaidhoo Kandu — no route description and no site-specific animal list — but the atoll's own copy groups the three together as the outer channels liveaboards come for, and the depth and current figures put it in the same class of dive.
