My SO is so motivated to get his certification. He has encountered a few problems along the way, but is determined to get past the problems and earn his cert. Several days ago, he got mask squeeze by trying to keep the mask "tight" on his face to prevent water from entering his mask. He wants to get back in the water ASAP. Is it okay to dive with having mask squeeze (he looks like a racoon...lol), or should he hold off until the bloodshot eyes and black and blue marks go away?
