Shore divers are frequently recommended to pack a snorkel if they must swim a long distance to their dive destinations. They'll save air in their tanks and have a more pleasant swim if they use a snorkel. You may avoid swallowing lungfuls of water and exhausting your diving tank by inhaling via the snorkel. The act of breathing out through the nose will tend to keep sand and other small particles from entering your lungs. A scuba diver uses a snorkel when swimming under the surface of the water. When not using the instrument, it should be stored in a pouch attached to the scuba tank or worn around the neck. A scuba regulator is used to fill the tank with breathable air before diving. Without a scuba compressor, which most home air compressors are not capable of, pneumatic tanks would need to be refilled often while underwater making them impractical for recreational diving. In addition to being useful for swimmers, snorkels can also be used by boat drivers while fishing or sailors while sailing. If you're a person who loves the water but doesn't want to get wet, then a snorkel might be right for you! Snorkels were originally designed as simple breathing tubes for underwater breathing experiments conducted by the Swedish scientist Gustav Vigfusson in 1872.
