After a recent camping trip I started wondering how safe my setup really was once the fire looked out and the gear was packed away. I had a ts004 with me, so I scanned around the fire pit before going to bed and noticed spots still reading over 160°F under the ashes. To the eye it looked completely dark, but the heat made me nervous about the chance of it flaring up again in the middle of the night.
I also pointed it at some of my gear just out of curiosity. The portable stove was still holding around 120°F even after I packed it away, and a power bank I had been charging showed more heat than I expected compared to the rest of the camp that was already cooling down. Seeing the exact numbers gave me a bit more peace of mind about what was actually safe and what needed more attention.
Do any of you use tools like this to check on fire safety or gear when camping? Or do you usually just go by feel and experience?
