I have been diving with this operation for the last 3 years. I understand there are a number of operators in Cozumel but not many have the boat and crew that Blue XT has. Her boat is large enough to accommodate 6 divers comfortably and has recently been refurbished with 2 brand new engines. So your off to the sites with speed. She also has one of the better captains on the island which is Nivo. He can drop you off at a site and pick you up within feet of your drift. Once on the boat he swiftly changes into your fresh tank with out a blink. Amazing and an excellent captain! Now the last part has to do with their DM. Pedro Pablo is phenomenal and stands as one of the best DMs on the island. He is highly regarded/respected among his own peers. The owner Christi is also an experienced business owner that caters to her clients. As I learned during my last trip, she is available to help you even in the wee hours if there is an emergency. That was a warm surprise and really respected her for all her efforts in walking me thru my issue. Overall a premier dive operation on the island.
