Did a basic beginners diving course and cannot complement the dive staff enough for their care, patience and help. A great bunch of people from start to finish.Boat crew were fantastic as well as was the food and facilities on board the Hallelujah. Amazing experience and now on to becoming a fully fledged diver.

Had a discover diving day trip in December 2013. It was the first time I dived ane was a bit nervous but this trip was really perfect for beginners like me. We were split into small groups. Our instructor Jo, was really good in explaining everything to us and took great care of us under water. I highly recommend discover diving to everyone who wants to try diving! Thank u Big Blue for a great trip! Read the full review on Trip Advisor

The team at Big Blue were fantastic especially Anna! She was great with my 13 yr old son helping him with his first deep dive. The whole operation from reservation, pick up, the speed boat, Dive Masters and lunch was faultless. A great credit to the entire team. Richelieu Rock was fantastic!
