I haven't seen it that good on the backwall Charlie but I don't doubt you for a second.

The visibility at Molokini is routinely 100+', but this time details on sand below the backwall were visible from the surface, even in early morning light.
Back in April 2003 I posted that as my "best dive ever". Still true.
