Sure, but nobody chose a wizard's hat or a dowsing rod, so there must be some cultural significance to it completely beyond my understanding?

Sadly (and incredibly) this is not always true: https://en.wikipedia.org/wiki/ADE_651

"as much as US$60,000 each. The Iraqi government is said to have spent £52 million on the devices" - Wow and no one thought hey let's test this baby out before we buy a thousand of them?

They did test them. Dowsing rods work very well in unblinded tests. That's a big part of why so many people believe in dowsing.

I'm gonna have to call BS on that. Finding water accidentally is astronomically more likely than finding a bomb.

Unblinded tests mean that the tester knows where the bomb is. Imagine you have a bomb on a table. Someone brings a bomb detector over and when they point it at the bomb, it indicates that a bomb is detected. Point it away, and it stops. This is a very convincing demonstration if you don't suspect shenanigans.
