How does the ProEar mask function?

The squeeze we feel during a dive is caused by the imbalance of pressure either side of the ear canal. While our ear canal is exposed to water and ambient pressure, our middle ear (which is on the other side of the ear drum and is connected to our nasal cavity by Eustachian tube) is still filled with air and experiences less pressure. The greater external force is able to push our ear drum inward, causing discomfort or pain.

With a ProEar mask, the ears are completed sealed off from the outside and air, at the same pressure as your nasal cavity, is able to be introduced through the Equalization Tubes into the Ear Covers. Therefore the pressure on both sides of the ear drum becomes equal. So as pressure and depth increase, the simple act of breathing air into your Ear Covers can significantly improve your enjoyment of diving.
