text: If the snorkeler unintentionally submerges the top part of the snorkel (i.e. looking from side to side), a conventional dry snorkel will have its only air passage closed off completely as soon as it senses buoyancy change but in the same situation with a IST 3D Snorkel, only the valves that are underwater will shut while the others will remain open, providing an unobstructed breathing path.
