My local eye doctor knows diving. He advised me to put in one only, low and left. The gauges are over there, on the hose and wrist. I use a stick-in, and it has stayed there.
Using this causes me some concern, as I don't think a stick-in optic is DIR.
lol.........question is, does he know his eye doctoring......btw, we do the same for some golfers, but we use high left(so they can read the score card monocularly).........
