The EasyDive Kit is a complete minimalist dive & snorkel system. Just grab and you are ready for your next water adventure. The kit incorporates the New Snorkelator - a patented technology that offers divers the ability to combine their snorkel with any diving regulator. Switch from snorkel to regulator with the turn of the dial and just one mouthpiece! No longer limited to the surface and quick underwater swims, snorkelers can take occasional deeper dives to explore the shallows, with less equipment than a full diver would require.
