Which are better for marking where you've been in an unknown area that is akin to a maze, pic related is where I will be returning to soon, this place is wierd, I shine my torch into it, and the light just fails to illuminate the environment.Not this exact place but the pipe up ahead you have to crawl under the concrete to get to.If the air inside is poisoned (storm drain) with methane or something flammable, then perhaps igniting a flare within the pipe is not a good idea, as it will set the environment on fire, but if I really need more light in there, then a high powered LedLenser and flares are crucial for navigating down there.I cannot afford NVGs also.
>>64763108What the goddamned fuck is this shit, why did it post upside down, how did that even happen?
chalk arrows and glow sticks nigga
>>64763108What is this zoomer backrooms bullshit."Fails to illuminate sooo unusual!"No, it isn't. It's an underground confined space with no ambient light or reflective surfaces. That's how that is.Your biggest concern shouldn't be methane, it should be sulfur dioxide, which will kill you in a few breaths without warning because you don't have a gas meter to tell you you're fucked.Also weapons board what.
Glow sticks are cheaper, safer, and glow for much longer.Chalk is also cheap and safe.There's also a type of line (the name of which I forget) which is used for cave exploring and spelunking, where you tie one end to the entrance and pull it behind you, and at regular intervals you add a little plastic arrow pointing back, so if you get away from the line and get back to it you'll know in which direction to go.
>>64763108Assuming you're being serious, get a reel of fishing line, tie one end to the entrance and spool it out behind you as you go. Theseus and the minotaur type shit.
>>64763172sulfur dioxide smells even at low concentrations, no? So it shouldn't be too hard to avoid if OP isn't retarded
>>64763269>it shouldn't be too hard to avoid if OP isn't retardedif
>>64763269NTA, and I don't know much about sulfur dioxide, but it might be a bit like hydrogen sulfide in that you can smell it at first but you quickly get used to it and no longer notice the smell, which can be lethal.
