Sedona Elite Dry Snorkel
The XS Scuba Sedona Elite Dry Snorkel is a dry top snorkel with a valve at the top and the bottom of the snorkel to keep water out of the snorkel. A small float built into the top of the snorkel will block the top when submerged and the splash guard around the top will keep water out.
even if some water does make it into the snorkel then the purge valve at the bottom will push it out whenever you breathe out.
XS Scuba Sedona Elite Dry Snorkel - Features
?Most snorkells are designed to be used by a variety of people including adults, teenagers and children but not everyone finds the standard size mouthpieces comfortable because they are too large. There are snorkels fitted with smaller motuhpiece to make use much more comfortable.
?A one way purge valve can be incorporated into the frame or nose section to allow for hassle free mask clearing. The diver just needs to tilt his/her head to allow the water to flow to the valve and be purged out.
?The main body of the snorkel can either be rigid or flexible each with its own benefits. Rigid snorkels maintain their shape and airway no matter the current or abuse but they can be cumbersome and will often break before they bend so pack them carefully.
Flexible snorkels can bend and flex and are made to keep the airway open and maintain their shape but in strong currents and rolled for long periods can distort.
|Snorkel Top Type|
?In its simplest form a snorkel tube is just open which obviously allows air to flow in and out of the snorkel as freely as possible but also allows water to splash into and enter the snorkel.
A deflector is a cap that fits over the top of the snorkel tube opening and uses a series of guards and vanes to direct water that splashes over the top of the snorkel away from the opening. It is not 100% guaranteed to prevent water from enetering the snorkel but they are very useful in choppy seas and makea big difference to comfort and convenience when snorkelling.
A Dry Valve builds upon the principles of a deflector by incorporating a float valve that will close the snorkel opening when submerged. Early versions of these valves were simply ping pong balls trapped within a tube that floated up to block the tube. Modern valves use a float linked to a hinging flap that closes over the top of the snorkel which are very responsive and hugely more reliable.
|Tube Cross Section|
?The cross section of a snorkel may not seem very important but there is a reason boats and ships have efficiently streamlined bows that cut through the water, massively reducing drag.
The same principle applies to snorkels. A snorkel with a flatter profile hugs the side of the head better and offers a more streamlined leading edge that reduces drag and helps to reduce or eliminate the flapping that can be created when finning quickly through the water.
Obviously you can't create a really flat snorkel without restricting air flow so a lot of snorkels will have a thinner leading edge but be wider than a circular profile snorkel to maintain the air flow efficiency.
