Here is a clip of a GPS device failing as the owner entered the Fyfield Down formation in 1999 (as discussed in Opening Minds). The device had 14 hours of battery life before its owner came into the crop formation. The batteries then drained within a few minutes once inside the formation. Also affected a few minutes before, were my Trek electrostatic meter, which lost all power, and a friend’s camcorder which would no longer record. Thus, a total of three devices seemed to strangely malfunction within the space of a few minutes. (And I’ve heard other people’s devices were also affected: apparently someone’s lithium video batteries wouldn’t take a charge for a year afterwords.)
In the following video, an Australian tourist’s camera stops working inside the East Field “OM” Formation in 2007. This is a phenomenon I have witnessed many times while visiting these formations. Yet every time it happens, it reignites my fascination with the subject.
