My son and I used Black Durgon for two days for 4 dives all together. They were top notch with the whole operation. Good Equipment, knowledgeable Dive Master, great dive spots and all in a no hurry atmosphere. We dove in early January and the water was very warm (low 80's), no wet suit needed. Sim was very cool and let us use some of the snorkeling gear for the evening and next morning at no charge. If I ever return to Caye Caulker I would use him again for sure.
