Just back from a shallow low-viz dive in water laden with sand and debris. Pleased to see that the cheap cover kept almost all of it out of my head.
This was the sum total of what filtered down to the head.
That sand on the second ring was washed down when I pushed the button to release the head. There's none on the second ring except there in the front center. The amount of sand held in that button recess gives you an idea of how lousy the conditions were. About 2-3' vis.
@Geo7, you have a reasonable concern. As @taimen pointed out, there's little that's hidden from the ambient pressure loop. In fact, the nylon covers that cover the loop hoses before the T-pieces hide a lot more (first pic).
The only covered connection of note is the O2 hose to the solenoid on the right above.
But as you can see, the "seal" around the hose is loose.
While you might conceivably miss a fine stream of micro bubbles, that wouldn't likely affect the dive. Anything significant would bubble right up the gaps around the hose.
