In the Netherlands we consider 6 feet of vision as clear water.
Navigation by compass is necessarily here.
If visibility is so bad you cannot read your compass it is (IMHO) plain stupid to go into the water. (Or you must have a very good reason to do so)
If visibility drops to zero during a dive I grab my buddy, use a tether line and we make a controlled ascent to the surface if possible.
I followed some classes in Search&Rescue.
One exercise was to find a object while blinded.
2 divers blinded tethered to a guide on the surface.
The guide on the surface knows the location of the object as it is marked with a SMB.
After some practice all classmates were able to find the object by following the instruction from the guide on the surface.
1 (Attention signal) +1 yank = swim out
1+2 yanks = go right
1+3 yanks = go left
1+4 yanks= swim back
5 or more yanks = panic attack
No yanks for several minutes means something happened. (Tether got wrapped around an object for example)
I found it very relaxing.
Just swimming hand in hand with your buddy and feel around while guided on a leash.
