We spent 10 days in Cozumel diving with Blue XT~Sea. We did16 tanks including a night dive and our first Nitrox dives. We are big fans. The Dive Masters Pedro and Miguel were very attentive and careful. We enjoyed long bottom times and saw spectacular scenery. We did most of our dives with Pedro. He went out of his way... More

My son and I booked Blue XT for our diving in Cozumel. I am recently certified and my son received his Open Water while in Cozumel. We could not have made a better choice for our diving. Small dive groups in the key. Two DM and six divers were in our boat. We saw boats that must have had thirty... More

We had an amazing four days of diving with Blue XT-Sea! We were referred by locals who dive regularly with Christi and her team, and we were not disappointed. Christi was great at handling our reservation/answering questions via her website and email before our arrival, and once there, she was in contact with us to discuss the final details of... More

We are newly certified PADI open water divers, but I felt we needed some extra instruction when going into the open ocean for the first time. I felt completely safe and comfortable with the private dive master my husband and I shared for our first few dives. Blue XT Sea Diving was exactly what we needed as new divers -... More

This was the 5th time I have dove with Blue XT and not my last since I am diving with them again in a few weeks again. My buddy and I did 14 dives on our last trip and they were fantastic. Christi's crew is the best in the business on Cozumel, Pedro, Mago and Miquel go way out of... More

Did four dives in two days with Blue XT-Sea at the Columbia 2x, Dalila, and San Francisco dive sites. There is plenty of life to see along the walls. All kinds of fish and coral formations that will blow your mind. Saw turtles and fairly large Nurse Sharks every dive. Pedro was our Dive Master and Mongo was our Boat... More
