Here's a short video of an Adult Spotted Drum and a Batfish that I ran across while diving on the northern end of Cozumel with Aldora Divers. When the weather allows and the experience levels of the divers on board are satisfactory, Aldora is happy to take folks where no other dive op on the Island will go. With the addition of a new boat, the Aldora VI, trips to the north will become the norm rather than the exception. From Adventure dives in search of sleeping sharks up north to the Spanish Galleon wreck with is 17 cannons and 2 anchors on the East Side, no one else will make these dives happen. With their own fill station with nitrox 32 and 36 for first and second dives and HP120's, you'll get more value for your diving dollars with Aldora Divers.
