This is in the 'cave diving' section.............ergo complete siltouts are a reality to some.
I certainly understand the potential for siltouts in a cave, as I've done cave training, but the type of siltouts being referred to within this thread, which would preclude you from seeing your HUD or your gauges even when placed flush against your mask, seem like they would only be possible if you were diving in pure muck, as was done by the divers that were scouring the swampy Florida Everglades when they were looking for Value Jet Wreckage after the plane crash in the swamps!
My point is, if it's that's mucky, hit the bar and forget the diving!
