Difficulty in equalizing and the possibility of getting ear infection are problems that can happen to any diver regardless of their experience. It can become serious enough to stop one from diving. The IST ProEar Mask is designed to counter most of the unavoidable effects pressure and water have on the ears to make your dive more enjoyable.

IST ProEar Mask features

Product Features

  • A: Optical Lenses - Prescription lenses are available in diopters from -1.0 to -8.0 in -0.5 decrement.
  • B: 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
  • C: Silicone strap - Mounted on swivel buckles, the strap with its large contact surface secures the mask to the wearer.
  • D: Ear covers - The soft silicone ear covers form a water tight seal between the ear drum and the cover. The pressure buffer was designed to have the same pressure as your nasal cavity mask when air exhaled through the nose is introduced through the Equalization Tubes. When ear pressure in the middle and outer area is the same, the “squeeze” from the ambient spressure is significantly reduced on the ear drums. Other benefits from keeping the ears sealed also include reducing the chance of an ear infection from water, plus improved sense of direction and warmth retention.
  • E: Equalization tubes - With a one-way valve placed inside each tube, air is allowed to travel only from the mask to the ear covers for pressure equalization and water clearance. The valve also prevents water from flooding the mask in the unlikely event of flooded ear covers.
