Blue Diving Mask -720p

Description: This is the first time i am trying out my new-to-me diving mask. it's us divers brand in blue, but looks sort of purple under water. this is a short video of me splashing around and doing quick breath holds under water.  (gopro footage comes out with large video files, even when i edit/render it.  i don't know what is up, my other 4k camera video edits just fine. anyways.)
