"Zero Viz" can be a term that can be differently interpretated between individuals and the environments they dive in. For example, (as you well know Claudia from this past weekend) that one does NOT or cannot (if they don't want to be closelined by monofilament or get nailed by a Lion's Mane Jelly fish <ouch!>) scooter in "zero viz" in the Pacific Northwest waters when the plankton blooms are so thick that it is "diving by brail" when swimming, let alone trying to scooter. Once again a perfect example of what works for some....................
