C-Waves Diving is a Not For Profit Dive School. Our mission is to encourage & enable as many people as possible to participate in active water sports to enhance health, well being and community interaction. Sign up to an open water course or come and try scuba diving with us at Osprey Leisure Centre, Portland, Dorset or at another one of the swimming pools that we use locally. Experience your first 'Astronaut Moment' and all the fun of zero gravity underwater.
