How do you define visibility? Is it the distance over which you can see and identify fish, your partners orange snorkel tip, the reef, or the blurry outines of things?
It seems like a stupid question, but people are always talking about how many metres of vis they had and I'm never sure if I'm picturing it right.
Thanks,
