IST Pro Ear Two Window Mask
Difficulty in equalising and potential ear infection are problems that can happen to any diver regardless of their experience. It can become serious enough to stop one from diving.
Solution? The IST ProEar Mask is manufactured to the highest standard and only the best available materials are used. It is designed to counter the most of the unavoidable effects pressure and water have on the ears so you can have more enjoyment underwater.
The Skirt:
Made from the best grade of crystal clear, hypoallergenic silicone, the skirt is soft and automatically conforms to a wide range of facial profiles.
The Strap:
Mounted on swivel buckles, the silicone strap with its large contact surface secures the mask to the
wearer.
Ear Covers:
The soft silicone Ear Covers forms a water tight seal between the ear drum and the cover. The pressure buffer created has the same pressure as your nasal cavity mask when air exhaled through the nose is introduced through the Equalization Tubes. Therefore the pressure experienced in your middle ear and outer ear is the same and the "squeeze" from the ambient will be significantly reduced. Other benefits by keeping the ears sealed include reduced chance of an ear infection from water, improved sense of direction and warmth retention.
Equalization Tubes:
With one-way valve placed inside each tube, air is allowed to travel from the mask to the ear covers for pressure equalization and water clearance while stopping water from flooding the mask in the unlikely event of flooded Ear Covers.
Benefits:
Pressure equalization can be very easily achieved with IST ProEar mask.
Prevents pressure induced ear ache.
Enhanced underwater hearing and sense of direction.
Stops dirty / polluted water from entering the ear causing infection.
