Tolerating low visibility

We started adding the American Academy of Underwater Sciences (AAUS) annual meeting proceedings this weekend.

I remembered this thread and thought someone might enjoy it:

FJ Cantelas and BA Rodgers. Tools, Techniques, and Zero Visibility Archaeology. In: EJ Maney, Jr and CH Ellis, Jr (Eds.). The Diving for Science…1997, Proceedings of the American Academy of Underwater Sciences (AAUS), Seventeenth annual Scientific Diving Symposium, Northeastern University, Boston, MA.

Vis is overrated.

Ever think you might want to be a commercial diver?
Now consider that the worst vis you have been in as a sport diver is exceptionally good vis for a commercial diver.

Good vis = I can see something.
Great vis = I can see it before I can touch it.

Even on those days when the job is in a place with a few feet of vis that is usually gone the moment you start working.

There are lots of tricks to be able to see things like instruments if needed like a bag full of clean water. With the bag against your mask and the instrument against the bag you can shine a light in to read it.

It does get easier with training, time and experience but for fun diving I think it is often just easier to dive where there is good enough vis.

Nice one! I'll remember that one. Better than 'flying manually and blind'
