About 10-15 minutes in, "Chris" uses a ghost meter to check the electromagnetic anomalies around the box. He shows himself moving the meter closer and farther away multiple times and when it gets close it beeps very quickly. Then at one point after moving it up and down under the box, he brings the meter back to the top to move it up and down above the box, but when he moved it past the box on the side, even though it was closer for a few seconds, it didn't beep or light up at all.
