>>2125257>i have some headlights, powerbank, 4 gas meter, good shoes, anything else which is important or useful?Make sure your gas meter is properly calibrated. Bring a minimum of three headlamps, check the batteries every single time before you go, spare flashlights. Honestly, below ground rappelling and belaying aren't something you should just do on the fly. Do you have a harness, rope, belaying setup, etc? You should know how to properly use all of that, and have the necessary gear before you go. Like the other anon said: get a hard hat too. Or a spelunking helmet. If you intend to go far, throw down glow sticks at every intersection you cross. If you see a cave-in picket, do not crawl over it/passed it. Don't crawl into any openings, it's a good way to go for a ride and fall down into an area you just can't climb out of. If an area is flooded, do not swim into it, wade into it, or try to cross it. The water could be contaminated, it could be deeper than you think, who knows.
I've had buddies that have done all of these things, but they're extremely lucky. This is a good way to accidentally get yourself killed. Take it seriously.
