That looks like great vis compared to some of the stuff I've been in!
Rob took us into a passage he said we WOULD silt out, and although it didn't look that bad to me, we DID. Amazingly, I was far less stressed swimming the siltout with the line in my hand, than I have been in some dark, hazy cave. And I've also swum third in teams in small cave with halocline, where you can't see squat as tail-end Charlie, but again, with the line in my hand, I'm just fine. Maybe I just need to okay the line in low viz cave? :)
Ditto. And when its really bad with dry gloves not feel it either.Quote:

Yeah, like when I was following you in Sandy's Hole! :-)Quote:

Yes, I migrate much closer to the line when it's silty. But did I remember where every possible line trap was? How easy is that bit of cave in order to do a lost line drill? Is it all grotto-y? Fortunately I've managed all low/zero vis sections of my dives without losing the line--so far!Quote:

Then we realized we couldn't see what we were "exploring" anyway and left for good.Quote:

Why floating line Andrew? It that just what's available or trying to keep it up off the floor? or?Quote:

Don't get yourself entrapped with line too thick to cut with a Z knife (or whatever you can reach)!!Quote:
