Imprex Hyperdry Snorkel

Regular price £19.95 £19.95 Sale In Stock

Brand: TUSA

Model: Imprex Hyperdry Snorkel

SKU: 53025-1

The Imprex Hyperdry Snorkel from TUSA is a great choice if you don't like water getting into the snorkel tube, as it has a special angled splash guard at the top that sits away from the main tube to deflect incoming water. If water does get into the main tube, an underside purge valve will release it before you breath it in. The flexible tube and mouthpiece have been designed to give as much comfort as possible when you are snorkeling.

Features

  • Hyperdry system: an angled chamber at the top helps to prevent water entering the main snorkel tube. If any water does get into this chamber it will drain through an underside purge valve without entering the air intake chamber.
  • Bottom purge valve has large drain chamber that clears water
  • Comfortable mouthpiece
  • Crystal silicone neck that flexes

TUSA Imprex Hyperdry Snorkel - Features

FeatureProduct Specification
Lower Bend
?This section of the snorkel bends the tube to angle the mouthpiece towards the mouth for a comfortable fit. A simple snorkel will have a fixed angle piece with a smooth internal and external surface that does not offer any flexibility.

Most snorkels, however, have either a semi flexible or fully flexible silicone section that offers some or complete flexibility over the angle and position of the mouthpiece.

For snorkellers a semi flexible section can some times be more beneficial as it keeps the mouthpiece close to the mouth whereas a scuba diver would prefer a fully flexible version that moves the mouthpiece out of the way of the regulator.

Regardless of the choice it is important that the corrugation that allows the section to flex so much is only on the outside of the snorkel. Ridges on the inside of the snorkel causes the air flow to slow and spin, taking more effort to breathe and creating dead air spaces.
Corrugated Flexible
Mouthpiece Size
?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.
Standard
Purge Valve
?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.
Yes
Rigidity
?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.
Rigid
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.
Deflector
Strap Retainer Type
?To keep your snorkel in position you need some kind of loop to attach it to your mask strap.

Two methods of strap retention used on most snorkels are a fixed plastic clip and a quick release assembly. The fixed clip allows for rapid insertion of the mask strap and vertical movement for a customised fit to the mouthpiece. This clip method is cheaper but does not allow for as much movement flexibility and convenience of a quick release clip.

The Quick Release method uses a two piece assembly, one piece is permanently attached to the snorkel tube and the other is fitted to the mask strap. The two pieces can be joined by pushing together and released at the push of a button.
Fixed
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.
Circular
Tube Profile
?A basic style snorkel is usually a J shape, a straight tube coming down to a fixed angle bend at the bottom with a mouthpiece on the end. Whilst this is very efficient for air flow and also makes it cheaper to manufacture the hydro dynamics of the snorkel through the water is not that great which can cause the snorkel to flap when moving at speed or in strong currents.

Most modern snorkels hug or wrap around the side of the head, creating a more streamlined profile through the water, reducing drag and pull of the snorkel

So pleased I bought a second

Used exclusively for snorkelling and bought as the purge valve had gone on my previous snorkel, I wanted a low cost replacement. This certainly fits the bill. I was so impressed I bought another for my wife who also loves it. Very easy to blow clear after a dive underwater, air flow is totally unrestrictive and after two holidays abroad is still performing well with no sign that the purge valve is leaking. Great product.
