Specialty and Technical Diving


The Cayman Islands has long been accommodating rebreather divers; here, you'll enjoy rebreather profiles, have gases, tanks and scrubbers readily available, participate in a rebreather experience or do a certification course – from rec to tek.

With virtually no bubbles, rebreathers offer divers a chance to interact with the marine environment, photograph and video aquatic life and enjoy eye-to-eye contact with marine creatures. Semi-closed circuit (SCR) and closed circuit (CCR) rebreathers are available for divers wanting to give them a try; full certification courses can be completed during a vacation. Rebreathers are also available for rental to those certified in their use. Currently CCR's offered for rental or training include the Evolution, Inspiration, Megalodon, Sport KISS, Classic KISS and Optima. You can also bring your own CCR and know that CCR tanks, bailout bottles and scrubbers are readily available. We are rebreather friendly! Inquire with your dive operator for choices of profiles and CCR support.

Operators offer a wide variety of trips and packages that range from Advanced Nitrox dives through Advanced Trimix diving to 100m/300 feet. Guided boat and shore trips are available with trained technical Instructors. Unguided dives for certified buddies can be done from shore to enjoy getting off on your own. There are many great offshore diving locations that allow exploration of both walls and shallow reefs. Boat trips are run in the mornings and afternoons. With the Cayman walls just minutes offshore, there is no easier destination than the Cayman Islands to explore the deep walls and go where no-one has gone before.


Nitrox is simply enriched air. When the scuba tank is filled, the percentage of nitrogen is reduced and the amount of oxygen is increased. (Different 'mixes' are available with different concentrations of nitrogen to oxygen ratios and so it is essential that each tank be tested prior to use). Nitrogen, as we all know, is the gas which leads to many of the limitations on divers and contributes to such problems as decompression sickness. By reducing the percentage of nitrogen it is possible to extend bottom time safely using specially formulated Nitrox tables. To be doubly safe, some divers continue to calculate their bottom time using air tables when diving Nitrox, thus giving them an extra margin of safety. One unexpected advantage of diving on Nitrox is that divers feel less tired at the end of the day. Our divemasters, in particular, find this of this great benefit. Nitrox is not without limitations, however. Because of the greater percentage of oxygen in the mixture, your depth restrictions are limited by the percentage of oxygen in your tank, but for recreational sport diving in the 100 - 130 foot depth range, the most common mix – nitrox 32% – is most suitable.

Nitrox 32% is available at all dive operators. For technical and rebreather divers, doubles, deco bottles, sidemount options and technical gases and scrubbers are on offer from select operators. The Sheer Deep Walls and the Sponge Belt, with incredible visibility of 300 ft. offer unparalleled, world-class technical diving, either from a dive boat or launching on a mere minutes’ swim from the shore.


There's been a lot of talk in recent years about TEK diving and while some people have embraced it as a new and exciting addition to our sport many other divers are mystified by the term and unsure of what it means. Undoubtedly most aspects of TEK diving are outside the scope of what most of us would consider safe sport diving, requiring very specialized training and additional equipment.


Cruise the reefs and walls James Bond-style. For kids five years old and even advanced divers there's nothing like the excitement of cruising on a scooter.
