Chris Davies – Owner and Technical Diving Instructor

Just six short years after becoming a certified scuba diver, Chris Davies gave up a successful career as a Mechanical Electrical Engineer and moved with his wife Sally to the beautiful Caribbean island of Saint Martin. There they started Octopus Diving, which has grown into one of the most popular dive operations in the Caribbean.


“Our goal has been to keep our Caribbean dive operation family friendly and cater to small groups of divers.” says Chris.

Having plenty of cold water diving experience in the UK has helped Chris prepare for the rigors of both commercial and technical diving. In 2012, Chris worked as a Support Diver for the CBS News program “60 Minutes“. In 2013 Chris dived, documented, and was instrumental in solving the mystery of the Ghost Ship of Saba Banks. Also in 2013, Chris was among the first to be recognized as a technical diving expert by the prestigious scuba equipment manufacturer, Scubapro.  Recently, Chris taught the first ever Normoxic Trimix course in Saba.

All this has lead Chris and Sally to open Caribbean Technical Diving and cater to that small, but dedicated group of divers that want to enjoy technical diving in the Caribbean and advance their technical diving training and certification.

Chris’s qualifications include:

  • IANTD Advanced Nitrox Instructor/Instructor Trainer
  • IANTD Advanced Recreational Trimix Instructor/Instructor Trainer
  • IANTD Nitrox and Trimix Gas Blending Instructor
  • IANTD Normoxic Trimix Instructor
  • IANTD Poseidon MKVI Closed Circuit Rebreather Instructor
  • PADI Master Scuba Diver Trainer
  • PADI Emergency First Response Instructor (EFR)
  • PADI Oxygen Provider
  • Scubapro Certified Scuba Equipment Technician

Being a certified Scubapro Regulator Technician has allowed Chris to get very familiar with the maintenance and operation of scuba regulators.

For diving in the Caribbean, my primary regulator first stage is the Scubapro MKII. I like it for its simplicity and with only one moving part, it’s easy to maintain and comes with a high flow port. For my primary second stage I use the Scubapro A700 on my right post. It’s lightweight and well balanced reducing jaw fatigue and delivers 300 cubic feet of gas per minute, exactly what a technical diver needs on long duration, deep, technical dives.

“I strongly believe that is essential for technical divers to be intimately acquainted with every piece of gear they are using and fully understand the reason for its existence”.

This is one of Chris’s principal teaching philosophies.


Sally Davies – Owner and PADI Master Scuba Diver Trainer

Sally is originally from New York. She began diving while completing her Masters Degree in Marine Science in Plymouth, England. Sally quickly fell in love with the underwater world and on a fateful dive trip to the Red Sea, she met Chris Davies (who was her Divemaster but is now her husband).  This is when Sally’s life became completely interwoven with diving and with Chris. Not long after this trip, with the help of Chris, Sally completed the PADI Rescue Diver course.  Chris and Sally then traveled to Indonesia, where she became a PADI DiveMaster and then shortly after, a PADI Instructor. She now holds the rating of PADI Master Scuba Diver Trainer and has certified well over 200 students. Sally also holds the French dive instructor rating of BEES 1, and is probably the first American female to do so.  This accomplishment is something to brag about…. so just ask her and she will tell you all about it!

Underwater photography became the focus of Sally’s diving when she was working at Stuart Cove’s in the Bahamas for the Fin Photo Department. She trained under the wonderful photographer Claudia Pellarini and as you can see by her photos in the gallery section of this website, her underwater photographs of diving in St. Martin are first class. Sally loves to teach scuba diving, and is an excellent instructor. She is also a boat captain, speaks English and French, and… she is a published professional underwater photographer.

Keiran Davies – Motivational Leader and Future CEO

Keiran plays one of the most important roles at Caribbean Technical Diving.  He is our motivational leader. In the morning he likes to  greet all of our staff and customers and instantly puts everyone in a good mood.

Never one to pass on an afternoon siesta, Keiran is always awake and ready to meet the divers returning from their course and trips.  He loves to hear their tall tales about their fascinating undersea adventures.  He is a keen learner and loves different languages.  Be sure to speak to him in as many different languages as you know when you are here diving or snorkeling with us.

Keiran loves to go into the water, but hasn’t been diving or snorkeling yet. He intends to start later in the year, but right now he is content to just splash around.

Although he isn’t the most polite of the our staff (he has been known to pass wind without even a “pardon me”) his smile will melt your heart.
