A dowser recently told me that's how he dowses. By detecting kinks in the Earth's magnetic field. Thus he detects underground water, buried objects, disturbed earth, graves, cables, etc.<p>He works for the state department of land management or somesuch. Apparently they all dowse there. They even have a preferred "dowsing rod". A retractable thing like a radio antenna attached to a swivelling handle. (According to the dowser rather overpriced)
Any service which register and share data on magnetic field changes? It might be useful for dog-owners not just to observe strange behaviour of the pet but to understand.
This is an example of the creative power of Evolution at work -- dogs that did not align themselves with the Earth's magnetic poles when peeing were simply been eliminated from the gene pool by the unyielding machine that is the survival of the fittest.
This must be the reason dogs feel earthquakes minutes before humans do. A couple weeks back I read an article here (HN) regarding earthquakes being linked to MF changes and solar storms. This aligns to that finding as well. Interesting!
Preregistration is one mitigation.<p>Perhaps another could be a trusted, HIPAA-compliant third-party log service for raw data that's immutable with a blockchain-like hash and timestamp.
