ScubaMax's Stalker Snorkel is perfect for free diving and spear fishing. The curved tube makes the snorkel unobtrusive. This dive snorkel is made with a large bore for easy breathing and clearing, also, the Unique Hepelex PTE tube offers superb flexibility while rigid enough not to vibrate during the ascent. Another great thing about the Stalker is that it is foldable for compact storage and also light-weight for easy travel.
