Snorkel America from Cressi is designed specifically for the needs of spearfishing and free diving. The ventilation is excellent, because the tube is shorter, has a large bore and is a well-connected anatomical shape without sharp curves. The tube is made from flexible, black material, and a soft silicone mouthpiece fits into the end; this is a swivel mouthpiece so it can be placed at the correct angle for comfortable and long use. The tube is shorter than a standard snorkel to lower the dead air space and allowing faster and more critical ventilation associated with the needs of the free diver or spear fishermen. The height adjustable mask strap holder has a modern catch.
