Because the dive shop in our hotel asked for 114USD for a 2-tank dive including equipment I ended up with Deep Blue, just via internet and telephone. No need to visit the shop.
They picked us up at the hotel by boat exactly at time, they had everything we asked for and in the correct size on the boat with them and they were flexible in changing our dive plans and accommodating our needs.
I had 3 different dive masters during my stay, All of them very experienced and lot of fun. The craziest was Aristid. He looked like he wanted to go for camping. He carried EVERYTHING with him. A speer to killed the lion fish, a scissor to cut of directly the stings and later on he fed the nurse shark, Lobster and Tiger Grouper with the fish. Were great dives - especially they see everything far earlier than I would - even the tiniest seahorse.
Between the dives they served fruits and water, the boats itself were small but with two engines really fast.
Overall very positive experience, I will go with them next time again. No doubt.
