I think being a professional is being good enough to make a living at it.By drilling a hole in one arrow,two holes in another,threeholes in another etc.you could still know where your at if viz is lost by feel.

First of all, I've said it before, I do not trust anybody else's markers whether they be arrows, cookies, clothes pins, etc.
**Edit: I guess that's not completely true...I guess there could be a time when I wouldn't have a choice. Like in a silt out in a popular cave, following a line blind to a "feet" arrow (not mine) to confirm direction of exit. In less traveled caves where there are none of those convenient 100ft, 200ft arrows, I would be dropping my own every 10 min's.
I would have put a personalized non-directional on the first T. When I got to what I "thought" was the second T I would know right away what had happened, that it was really the first T. I could exit without swimming all the way back the way I came.
The illustration of the "expected line layout" shown is actually LESS complex than I have seen, not all that long ago, the line from P1 to Olson sink.
At one time it had a T at Pot hole, (2) marked jumps [Wishbone and Cisteen], back to back arrows at the halfway point between P1/Olson another T at the Crossover.

It's bad luck to be superstitious.
Each diver in the team places a personal cookie at any tees. The max penetration marker is a single marker that the last diver places on the first dive when someone on the team calls the dive on thirds. On the traverse from the other entrance the last diver in the team picks up the single marker. Any other markers left in the system will be navigational and each diver picks up their own.

Ya know, I hit this snag recently with a cave system that doesn't have much traffic, and famously with a few circuits in it, all diciley marked. I wanted to do a traverse. I found a ridiculously simple solution - mark half your markers with the letter of the leaving point (let's call it "L") and half with the place you're goiing to (let's call that "T"). Then at ANY T (and some of them were 4 way T's) put an L on the leaving point side and a T on the to side. That way, you always konw which way goes where.
That system sucked up over 30 markers, and I still ran out and had to improvise along hte way! The improvisation was to SCRATCH a L on any old marker on the leave side, and scratch a T on the to side.
Worked great.
