Bats in the belfrey? sorry couldn't resist
If you leave the light on as a beacon what is to say your buddy is exiting already and not going deeper looking for you and now you have just reduced the burn time of that light. LED or not. And what if you left that light there in a silt out turned on or not would it really help that other diver?
I believe the line arrow left behind, Team awareness and alertness and a smart head on your shoulders are all that is required to permit YOU to safely exit the cave in tact. Your buddy close behind or ahead of you.
My idea & what I teach is to place the spool/reel clip, or double ender on the line, after I relocate the lost line to indicate the direction you are travelling, to what you THINK is the exit direction. If you confirm it is the wrong direction (by finding an arrow pointing in the opposite direction, or other means) turn around then reposition the clip/double ender, when you reach it again(double ender for a spool) change it to the direction you NOW think is the exit, the direction you are travelling. If I am looking for you & come across this configuration I know which way you travelled when you were last at the spool/reel.
This gives no conflicting exit direction to another diver & lets your buddy know which way you are currently travelling.
It is paramount for us to never place a directional arrow on a line that does not definitely point toward the nearest exit.
The clip has to be clipped somewhere & it should be the travel direction indicator. Why waste time getting out an arrow?
I hope this clears my ramblings up!!
Yet, I am getting this growing uneasy feeling that people are putting first these HYPOTHETICAL teams, who are very unlikely to arrive exactly THEN, and get into trouble while there is a temporary stray arrow placed - instead of worrying about the team that is actually in acute emergency, trying to solve possibly a life threatening problem.
Your arrow MUST be in the direction of the EXIT. This arrow as Jim has suggested can be left behind to communicate to the buddy that you have searched and left the cave.
I'm glad you weighed in. I agree with most of what you have said and respect your opinions. But statistically team alertness, awareness and smart heads have not always prevailed. If so, we'd have no need for accident analysis.
Having said that, I think the odds that my buddy would run across a lit backup light left behind (say that 3 times fast!) would be greater than the odds of him seeing an arrow I left behind by itself. Especially since a stressed diver making a hasty exit could very likely have tunnel vision (no pun intended) and miss the marker while focusing on the exit. As you stated, both divers are in effect "lost" until they reunite. I would think that seeing my buddy's light on the line would have a re-assuring effect knowing that he had also found the line and make for a much less stressful exit on my part.
The accident several years back at Little River around Thanksgiving is one that especially sticks with me. They were also from Texas and I had met both divers in the parking lot as we were finishing a dive and they were gearing up. I recall later reading one of the comments from the survivor as something along the lines that once he cleared the siltout and headed out, he kept thinking (hoping?) that his buddy was ahead of him, up until the point when he hit the cavern zone. I'm sure he'll play "what if?" for the rest of his life.
In regards to the reduced burn time by leaving the light on, that doesn't concern me in the least. I put fresh batteries from different batches in my lights whenever I go cave diving. Using those same lights for multiple night dives in the course of a week has taught me that the burn time far exceeds my gas reserves, even on CCR. In a worst case scenario when leaving a light behind, I end up buying new batteries, or a new light, if I fail to recover it. My buddy is worth the $150.
Finally, as I stated previously, my decision to leave a light would depend on my current situation at the time. If I still have a working primary, another working backup, have found the main line and feel that I can exit in reasonably short order I see no reason not to. Why carry emergency equipment if I don't use it in an emergency?
If you choose not to leave behind an essential piece of equipment I can respect that decision.
As others have pointed out, you may actually be dropping markers that will confuse exactly the person you are attempting to save or locate if you put arrows that "break" the cave navigation. It's not just some hypothetical team that might come along later.
