You're being generous. :D:D Homeopathy might at least have some placebo effect.

I vote for Dog.

I'm wondering how much the magic mice that smell explosives are going to cost? I can just imagine how chaotic CPs will become with mice running around.

Glorified dowsing rod, that's been sold under various names over the years.

dowsing rods work. I've seen farmer geezers use them quite successfully over the years for finding good wells.

I've seen guys pull whole eggs out of kids' ears for years. That doesn't make them sorcerers.

No, they don't.

Edit: This link actually includes the "high-tech" dowsing rods mentioned in the OP...

apples and oranges. the farmers did not put the water in the ground, they found it.

I'm as skeptical as the next guy, but I've seen on many occasions well witchers and farmers all use dowsing rods to come up with the same location independently that yielded a very good well, in dry areas where water was scarce, and the cost of drilling dry holes couldn't be afforded by said farmers.

so, there might be something to it...

Brilliant, simply brilliant.

Scammers like these, who sell ineffective devices or training, are all too common in just about every industry. They'll show you all kinds of made-up stats and records of success, but in the end, the stuff they sell is junk and doesn't work.

Unfortunately, some of them actually BELIEVE in the junk they're selling, and many of their customers believe in it, too.

All independent tests ever conducted showed that dowsers had the same record of success as random chance.

and the TSA is the K-tel, or Demtel, or whatever is your late night TV snake oil salemans dream come true - to the tune of $millions...
