Welcome to Blue XT~Sea Diving!

Hard to believe, but April 2007 marked our 5th anniversary – a milestone we could never have reached without the support of our customers, friends, suppliers, staff and the fine and resilient community of Cozumel itself.

Founder, owner and Texas native Christi Courtney started Blue XT~Sea out of her island home, tooling around in a moped with a “Keep Austin Weird” sticker on the gas tank. With very little advertising and much goodwill, we grew to become one of Cozumel’s best-loved dive operations. It wasn’t just the famous surface-interval muffins and other snacks, it was the personal service that has set us apart from the very beginning. In April, 2005, we opened our first storefront — just behind Chedraui. A year later we launched our second dive boat, Bandida II, operating alongside our original boat, Shamu and providing greater choices and flexibility for our customers. Last September, we moved to a larger and more welcoming shop located on Calle 5, less than a block from the waterfront.

Cozumel is the ultimate dive paradise, offering more than 20 spectacular dive sites, mild tropical weather, an easy drifting current and crystal blue water. With cathedral-like deep coral formations, stunning walls, shallow reefs and even a few wrecks, it caters to divers at every skill level. No matter which site you dive, you’ll likely encounter sea turtles, spotted eagle rays, angelfish, snapper, grouper, splendid toadfish (Cozumel’s signature species) along with spectacular coral, sponges and gorgonians. And when the diving is over for the day, enjoy the dining, entertainment and pure fun available on this jewel of an island just off Mexico’s Yucatan peninsula.

We can get you trained and certified, provide gear rental, even help with hotel reservations — and of course take you on some of the planet’s best underwater excursions.
