Anthony, In a message dated 97-03-01 01:47:12 EST, you write: << Hey, you think you're crazy, you should try Humber Bay, just off Toronto, where some of us went diving last Saturday. Viz measured in millimetres, if that, with sort of a brown glow to the water in the first few feet and solid black below that. Much too much mud coming down the Humber with the recent thaw and rain. I had to bring my light to within three inches of my mask to see the filament glowing. The wind, coming straight in off the lake, was cold enough to permanently take a brass monkey out of the gene pool. Sunday afternoon we went ice-diving up in Kempenfelt Bay. Six foot viz, the hole was close enough to the wreck of the Morrison, and it was really peaceful by myself under the ice and it didn't feel cold at all. -- Anthony DeBoer http://www.onramp.ca/~adb/ adb@he*.re*.or* (here) adb@ge*.co* (work) #include "std.disclaimer" -- >> ====================================================== Sounds like some really great diving Anthony! I'm curious as to how you managed to read any gauges during this dive - or did you just wing it on intuition ? Your description of the visibility exactly describes some diving I did in the Kentucky lake section of the Tenn. River many many years ago. We could not read gauges because if they were close enough to get any light on they were too close to focus on. You could get a rough idea from the blurr if there was enough contrast between needles and faces on analog instruments but digital displays would have been useless. We also used J valves because even though you could often tell by the breathing through a double hose regulator about where you stood supply wise the work level and concentration made this somewhat unreliable. I haven't done anything in this kind of vis in a long time and wondered if you knew some new tricks I hadn't heard of.
