We booked our first night dive with DSM and the whole experience was wonderful. The briefing was comprehensive, the guide was very friendly, and the equipment was in good order. It was our first night dive and we were a little nervous, but DSM helped make it a great experience. I even left my camera at their shop by mistake, and they had kept it in a safe place for me. We were quoted slightly less by other dive shops, but we were glad we went with DSM.
