Buoyancy Control Device or BCD is a piece of diving equipment containing a bladder which is worn by divers to establish neutral buoyancy underwater and positive buoyancy on the surface, when needed. The buoyancy is controlled by adjusting the volume of air in the bladder. The bladder is filled with gas from the diver’s air tank or from the diver’s mouth. BCD’s come in several styles including the most popular, weight integrated.


Chip McLeod has been living and working on Grand Cayman since the 1970’s. Chip is at the helm most days. He can be found chatting away to our customers as they book in their daily activities. “What can we talk you into today” can be heard all through out the day at Ambassador Divers.


Depth gauges display the equivalent depth in water. This is a fundamental piece of diving equipment that must be present during all diving activity. Depth gauges come with both analogue and digital displays.


Enriched Air Nitrox refers to any nitrogen/oxygen gas mixture with an oxygen concentration higher than the 21 percent found in normal air-32 percent oxygen is the most common–and tanks filled with EAN are often clearly marked with a nitrox tank band and have the mix percentage written somewhere near the tank valve. It is this higher percentage of oxygen, and the proportionately lower percentage of nitrogen, that allows divers to lengthen no-decompression limits, shorten surface intervals and get an added safety buffer for decompression sickness in certain diving circumstances.


Fins are a necessary piece of diving equipment used to propel the diver through the water. There are two basic styles of fins, open heel adjustable and full foot. Open heel fins have an adjustable strap that allows you to snug your foot into the foot pocket. You need to wear wetsuit boots (booties) with these fins, which is necessary for colder water and great protection for your feet while walking on shore or a boat deck. Full-foot fins have a foot pocket that slips on like a shoe. These fins are popular for warm water diving, especially from boats and are the most popular among Cayman Islands dive operators.


Gear Bags help you organize, protect and carry your scuba diving equipment. Your main bag needs to be big and tough enough to hold all your gear and stand up to the abuse of salt water. You’ll probably want secondary bags, such as a lightweight mesh bag, for your mask, fins and snorkel, or a padded bag for your regulator.

Lawrence Cook is the foundation on which the Ambassador Divers house is built. He’s a little bit like a soft boiled egg, hard on the outside but soft and gooie on the inside..and he smells a little bit like an egg too.


Multi Level Diving allows divers to maximize time underwater without following strict table no decompression limits. Ambassador Divers offers daily multi level dives on some of Grand Cayman’s most spectacular wall dives. These profiles usually have a maximum depth of 100 feet, followed by an ascent to the top of the wall around 60 feet. The wall dive ends with an ascent to the safety stop, and the the dive boat.


Nitrogen Narcosis is a reversible alteration in consciousness that occurs while diving at depth. It is caused by the anesthetic effect of nitrogen at high pressure and may be completely reversed in a few minutes by ascending to a shallower depth.


Open Water Certification is the entry level diving certification offered by Ambassador Divers.
As a certified PADI Open Water Diver, the most widely recognized and respected rating in the world, you have the freedom to dive with a buddy independent of a professional. For more information on receiving your Open Water Certification click here.

Tank Pressure is the amount of air pressure inside your scuba diving cylinder. A scuba tank is considered to be full above 2800 PSI.


Underwater Photography is the process of taking photographs while under water. It is usually done while scuba diving, but can be done while snorkeling. Ambassador Divers offers courses in underwater photography. Contact us here to find out more.


Visibility is the distance you can see underwater in a horizontal fashion. The Cayman Islands are home to some of the best visibility on the planet, boasting 100 foot plus visibility on most days.


Wall Diving is where the Cayman Islands diving community hangs it’s hat. These dramatic drop offs circle all three islands, starting between 40 and 60 feet falling off to 6000 feet in some areas. Ambassador Divers offers daily two tank trips to some of the most amazing wall dives the Cayman Islands has to offer.


Xtreme Sports, although the origin of the term is unclear, it gained popularity in the 1990s when it was picked up by marketing companies to promote the X Games. Activities categorized by media as extreme sports differ from traditional sports due to the higher number of inherently uncontrollable variables, scuba diving is no exception.
