"Odies ding ding", as this site is also called, is a little wall starting at 24m/80ft and drops down to a maximum of 33m/110ft. There is also another section of the reef going down to 40m/130ft for the diver who's good on air consumption. Here you can see thorny oysters along the wall and the rare black coral (it is actually white) which is one of the highlights. You need an experienced guide to find this place as there are sometimes strong currents which might drift you away from this small dive site. Nitrox is recommended
