Me and 13 years son Lucas diving whith Manta Diving for 3rd time since 2013. Its always a pleasure to dive whith them, both Ollie and Ben are so proffesonal divers. We dived the Blue Hole it was grate and we also did a nightdive. I was a little bit scarred before we went down the dark water, but Ben just said, it will go fine!! 
We always feel very welcomed and meet so many nice divers. If you need anything they fix it. Not to forget the one and only happy smiling and welcoming Rachel. I really recomend Manta Diving.
