The Supernova Dry snorkel has a unique Splash Guard at the top which greatly reduces the entrance of water during use on the surface. The special Valve on top seals the tube as you dive, almost totally preventing the entrance of water when the snorkel is submerged. The end part has a corrugated piece that is smooth on the inner side and keeps the snorkel away from the mouth during use when scuba diving. A special water collection well, with a large elliptic valve, allows quick and easy expulsion of water. The replaceable angled mouthpiece and corrugated tube section are both made from Hypoallergenic Silicone adding comfort and function. A quick release snorkel keeper and ergonomic contoured shape make this one great snorkel.
When choosing a snorkel you must follow the following rules:
• Have a simple device
• When breathing, provide minimal resistance
• Easy to blow out the water in it
The longer the snorkel and the smaller the inner diameter, the greater the resistance to breathing.
