This is my third stay in Thulhagiri and my twentieth in Maldives.
As an old PADI DM, I reckon Sub Aqua Dive Center is an excellent, clean and efficient diving facility.
Arndt and Candy are superb in briefing, guiding and keeping the costumers satisfied. Diving spots are carefully selected (HP Reef, Paradise and Jenkins Point on Top) depending on the divers' skills and wills. Safe and high quality scuba equipment (including 15L Nitrox tanks) is usually available. Prices are relatively cheap.
I would recommend this Diving Center as the best facility in North Male Atholl.
