Equalize underwater ear pressure when scuba diving by pinching the nose and blowing out, wiggling the jaw or swallowing. Learn to equalize a scuba mask by exhaling through the nose with instructions from a scuba instructor in this free video on scuba diving.
The IST Pro Ear mask is perfect for divers who have a problem equalising their ears as they dive or have ear infections. A one way valve is placed inside each tube, air is allowed to travel from the mask to the ear covers for pressure and equalisation.
To assemble scuba equipment, hook up and adjust the air tank, the regulator, the valve and the pressure gauge. Make sure the scuba equipment is working and has the correct readings with tips from a scuba instructor in this free video on scuba diving.
