Good Viz/Bad Viz:
Factors Affecting Underwater Visibility
The primary reason we venture into the deep blue beyond is to see what's there, and if we can't see, or can't see much, then we kind of miss the whole point. By understanding more about visibility, we can hedge our bets against the odds of a bad day. By adjusting our underwater techniques and procedures, we can maintain our comfort and safety even when the visibility is less than we hoped for.

But many divers have never given the instruction booklet more than a quick read to find out which buttons they need to push to display the most basic dive information, and off they go. The author invites you to take a closer look at your dive computer.
