Questions and Answers for IST Pro Ear 4-Window Scuba Dive Mask:
I have a problem pressure equalization. I have been on only 1 dive trip of 1 week duration (Bonnaire). but could not dive for about 1.5 days due to ear tube blockage. I swim everyday in a pool and have no problem equalizing. when scuba diving equalizing becomes a problem as I must squeeze my nose and blow, but as i continue to dive it gets harder and harder to equalize. Can this mask help solve that problem? If so how does it work?
