What should I take to explore the basement?

Adventure in the basement? The flashlight is for sure. Spare flashlight batteries, as well as emergency food, biscuits and the like, there is no signal in the basement, and the mobile phone is not used. It is best to have real-time contact with radios, as well as night vision devices, cameras for recording adventures, compasses, and signs to prevent getting lost. Finally, pay attention to safety and don't go to dangerous places.
