I’ve got a newer diver in my dive group who looks like a cork in the water.A diver on my recent trip was vertical in the water, kicking up the sand beneath her, so I tapped her on the shoulder and pointed down. Afterwards she came up to me and said "Was I kicking up the sand?" She had no clue.
We’ve been moving his tank around, trim weights, the like and he just will not go flat.
Eventually it’s a personal discomfort in the water thing.
I’ll say the unexpected benefit has been that silted out night macro pictures have a cool sci-fi look to them.
He’s a great dude to hang out with, and loves being in the water, so I’m not giving up hope w him.
