When is bad vis a problem?

[bcellreceptor]

In Northern Cali (Monterey), I've had a few dives where there was essentially zero vis, but only for part of the dive. At about 30' things tend to clear up. Therefore, I'll often descend to a 20' bottom and then swim along the bottom away from shore towards deeper water. Between 20' and 30' the vis commonly will clear up, making for an awesome dive.

I have had my buddy hold on to my tank so he knew where I was. Low vis but we were breathing "Canned Air" underwater so it was all good!
