ProEar Mask – Instructions for use

General comments:
The ProEar 2000 is not just another mask but is indeed an entire new concept in diving safety and comfort. As an entirely new product, it takes a little getting used to. The silicone ear cups, equalization tubes and especially the strap configuration take some time to get used to but after one or two dives the ProEar becomes as natural and comfortable (even more so) then the standard mask you have been diving with. The increased sound and hearing capabilities also takes getting used to.

Please try this on for the first time in a pool if possible.

How to Use ProEar2000:
When you put on the mask it is preferable to hold the ear cups in the palm of each hand and pull slightly apart as you slip the mask over your head. Make sure that as little as possible of hair gets into the ear cup. Make sure that the ear cup covers the entire ear and that the ear is in the middle of the ear cup and that the silicone seals are not folded or bent. It would be helpful if your buddy could check the seals and positioning of the mask.

Make sure the mask is snug but not too tight, make sure the straps are sitting well on the back of the head and if you are using the optional top strap, adjust it only after positioning the mask and adjusting the back strap. Do not tighten down the top strap too hard. The main strap carries the ear cups (which can be adjusted). You will note that the strap sits a little lower than normal due to the fact that it supports the ear cup. This slightly lower positioning takes a little getting used to but should not effect the sealing of your mask. In any respect, if this happens then it is recommended to use the optional top strap.

When you begin your dive, descend slowly while very gently blowing air through your nose, the air will go through the tubes (and the one way valve which prevents a back flow of water in case of flooding, this valve may "whistle" slightly if you blow too hard) into the ear cups and help equalize the pressure in your mask and ear cups thus creating a "closed circuit" system of ambient air pressure. Do not blow too hard. You may need to pinch your nose shut (as normal) occasionally to help with the equalization.

If you get water into the ear cups (through leakage or taking off your mask), it is possible to drain out the water while diving. With your head facing forward press the top of the ear cups against the head and blow air through the nose. The increased air volume should push the water out (through the drainage cuts at the bottom of the ear cup). Due to the slight resistance caused by the one way valves located in the air tubes it may be necessary to push the top of the mask against the head as well. This can easily be done using both hands. It is important to note that while sudden flooding may involve cold water entering your external ear canal it will not involve any increase of pressure as the entire system by definition is under the same ambient pressure all of the time.

If water persists to stay in the cups then try clearing one ear cup at a time by pinching shut the tube on the opposite side and then blowing air through your nose.

Prior to use, make sure you wash the mask carefully, especially with a brand new mask, use soap, toothpaste or lens defoggers. It is also recommended to wash the ProEar 2000 mask carefully with fresh water and dry properly after every dive.

Diving with a Hood:
It is possible to dive while using the ProEar 2000 mask with a hood. There are basically 2 options:

  1. Put the hood on and then peel it back off the head, place the ProEar mask on your face and over your ears and then carefully place the hood back on the top of your head over the ear cups and mask straps.
  2. By using the specially designed ProEar hood which will be available soon. This hood will allow for you to put the mask on over the top of the hood.*

* It is essential in most northern climates to dive with a wet suit hood, or semi-dry or dry suit hood year around. When using the ProEar 2000 mask it is impossible to put the mask on over the top of the hood unless you make a hole in the hood at the exact place where the ear cups are placed. The hole should be roughly the exact same size as the plastic covers of the silicone ear cups. That is slightly smaller than the actual silicone seals so as to allow for the stretch factor of the hood. The size and position of the holes actually should be made while wearing the hood over the mask and ear cups so as to make sure the position and actual size are correct. In this case, you should put the hood on then place the mask over the top and once the ear cups are in position pull the hood out slightly and place the silicone cups in position will making sure that the seals are sitting correctly against the head. Once the cups are properly positioned then return the hood to its normal position and you are ready to dive.
