If scuba diving feels like flying across a foreign planet, CCR diving feels like piloting a spacecraft through the galaxy. The power and potential of CCR diving will change your dive career, as it has ours. The JJ-CCR is one of the premiere E-CCRs on the market, and we are thrilled to offer courses in one of the best training environments on the planet – the beautiful cenotes and coral reefs near Tulum, Mexico.
