Yikes! The Thai military has purchased at least 500, and as many as 2,000, of these widgets at better than $30,000 each. Do the math. According to the brochure, they detect just about any bad stuff you can name...bombs, drugs, ivory, currency, whatever. "Poppy, cocoa, and marijuana planting areas." Detecting chocolate is nice, but what about coca, from which cocaine is derived? No mention. Hmmmmm. Distance is not an issue..."any thickness of wall can be penetrated, whether concrete, metal, brick or lead." No batteries too!
Similar devices have been used in Iraq, apparently. I'm guessing locales like Iraq and Thailand are good targets for the woo-meisters. Thailand is a world leader in woo, but dowsing has no tradition here; the device looks and feels like any other high-tech mystery box from the West, and few are aware of dowsing's very questionable history.
It was disappointing to see Thai media-darling/forensic scientist Khunying Pornthip defending the device. She gets trotted out every time there's a high-profile murder here in Thailand. Ask a Thai to play word association with her name, and the result is inevitable: "big hair."
I had assumed she was perfectly competent in her craft, but after her assessment of the glorified dowsing rod (well, it's not 100% accurate, it needs to be operated by someone in good physical condition, blah, blah, blah), I now have doubts. Having used the divining rod in the past as a means of detecting bomb residues on corpses, it seems she is now forced to defend its viability or risk humiliation and the wrath of victims' relatives. The military pu-yais ("big people") who ordered the device are in a similar predicament. If they actually recognize the error of their ways, one shouldn't expect a public retraction, but a quiet discontinuation of usage of the "GT-200."
At least in the case of the military, corruption is a reasonable assumption. Let's be generous to the generals, however, and give them the benefit of the doubt. How then, could numerous public figures claim that they've used and validated the device to their own satisfaction? Well, Buddhists (better than 90% of the Thai populace) are familiar with the power of the mind, but sometimes forget that its greatest power may be in its capacity for self-deceit. Witness a gaggle of dowsers exuding supreme confidence in their talents in a double-blinded test, performing no better than chance, and offering up the usual rationalizations (sun spots!) for their failures. It's a five part series, and highly entertaining:
Finally, here's a wonderful BBC expose of a near-identical widget. The company owner doesn't even deny that the ADE651 is, essentially, a dowsing rod.
In all seriousness, it's likely that lives are being lost over this dressed-up medieval artifact.
