Hi Christian
My partner and I were there in March 2013. Dive and Sail were the operators then too - and we dived mainly the house reef, Chaaya. The dive centre was good. Sorry but can't really recall their photo facilities. I'm pretty sure I took my system back to the room each day - it wasn't far. We did 3-4 dives a day and used Nitrox. Accommodation was very good. Food nothing short of superb. Water temp a toasty 28 degrees. Lots of shore diving. Entry was though a slightly odd protective encircling breakwater.
Best diving in the Maldives? Hmm, that's quite a boast. It was good: all the usual reef fish, some rays (mainly Eagles), schools of blue-stripped grunts. Some macro but mainly wide-angle. We did a couple of boat dives with them including the locally much-touted "Fishhead" site. The current was r-i-p-p-i-n-g and we spent a lot of the dive reef-hooked in trying not to lose masks, cameras etc. Very good hard and soft corals at Himedhoo Tila. Malhos Tila was good with overhangs, soft corals and Gorgonians.
If this seems slightly less than enthusiastic.... it was a slightly strange trip for us. Lots of equipment failures or weird happenings. I know this sounds odd, but we both found a curious, rather gloomy, atmosphere to the diving - especially around the entry points. For the first time ever, we were actually quite glad when the last dive finished. Weird.
As I say though, the resort is fabulous and the diving pretty good.
