New full face mask
I tried the mask in our exercise pool. The seal was very tight. I knew the air comes in through the snorkel, It goes out the two relief valves near the ears. AS compared to conventional gear that make a bubbling sound. That was distracting in our small pool. I have yet to learn about that noise in the ocean. In snorkeling silence is golden because the fish may be worried about the sound. We shall see about that. Has anyone figured out how to make a silent relief b=valve?
