Dale, unless there was someone else there to report the viz, how were they to know how bad it was going to be? I know, around here, you can look at the water and know it's going to be bad, but not how bad. And we CERTIFY people in less than ten feet of viz, when we have to. If all the DIR divers in the PNW stayed out of the water when the visibility had the possibility of being very poor, we wouldn't dive much . . .
