"If you’re looking for an operator with knowledge, flexibility, and personability, look no further! Diving with Marc & Hannah was one of the best diving trips thus far - essentially a personally tailored couple days where they provided excellent guiding in and out of the water. Thanks again for the good times Marc & Hannah."

Open Water Course - Need to know

What goes on below the surface? Ready to find out? And to become a certified diver and enter the underwater world where you will see incredible things, beautiful fish, colourful reef, and here in Tulum the stunning cenotes? Scuba diving is also a great way to meet amazing people. Upon completion of your SDI Open Water course you will be certified to dive to 18 metres and the SDI certification is recognised worldwide.

This course usually takes 3 days to complete. It includes theory, skills practice, and application practice. The skill practice and first 2 dives are done at Casa Cenote. The last 2 dives will be done in the ocean. This course is very flexible with some or all of the theory open to completion at home prior to arrival.  You will learn everything you need to become a competent, safe diver e.g. how to clear water from your mask while underwater, how to share air with another diver, and how to control your buoyancy so you are "weightless" in the water. ​
