Herd about a couple of people having that happen it happened to me on the Ancient Mariner but i was all the way at the front of the boat like one way in one way out and my buddy stirred up the Silt and i couldn't see anything so i was looking around and starting to panic and then i just laid flat on the ground took a few deep breaths checked my gauge had 1900PSI then i put it back then felt my way around and found the door (guess removing my mask in the pool and feeling the tile on the pool to find my way around was good training
) and i mentally knew that to the left was the other door then go straight out i did that came out and my buddy was freaking out but i am fine i used about 600PSI to get out but when we go to the surface my buddy kept saying dude i am so sorry i was like its fine i am not dead nor am i hurt so i am fine just be more considerate next time and when we get in the pool Monday i will tell the instructor to show you the reverse frog kick its your best friend in wrecks. :cool2:
