With all respect, I wonder how people can adamantly insist that dowsing rods work, despite all the evidence to the contrary. If they worked, REALLY worked, then there would be at least one reputable news article about it.
They're a gimmick, sort of a modern-day remnant of the alchemy/sorcery days a few centuries back.
You broke the code. Seems like many people have not.
