Dowsers can locate geopathic stress zones which can cause disturbance to humans, and this in turn can impede medical intervention.

Kathe Bachler, a teacher from Salzburg, published a book of her research in the 1970s where she dowsed over 3,000 houses, apartments and workplaces  in 14 countries (mainly local to her in Austria and southern Germany). She gained the support of many doctors and professors in her work, as the references show. In the book the weight of evidence is compelling.

Bachler concluded that 95% of all children’s problem behaviour was made worse by earth radiations where they slept or studied.
She also studied over 500 cancer cases among people who were found to be sleeping on geopathic zones. Previous occupants, sleeping in the same were also found to have died of cancer.

The radiations she detected by dowsing were from 3 sources – 1) underground streams and 2) some geological faults 3) regular grid pattern lines named after Drs Curry and Hartmann. She found that the grid intersections were the problem areas where small vortices formed.

The direction of the water flow pushed or pulled blood and life along a human body associated with characteristic illness.

Strangely, most dowsers now detect that the influence of the Curry and Hartmann grids has diminished and so it is common practice for dowsers to look only for streams (and then only the geopathic ones – not all streams are geopathic) and harmful geological faults. Inexperienced dowsers may detect all streams and faults and thus could have worrying false positives.
I can still detect the Curry and Hartmann grids, but I find them to be weak and the Curry grid the stronger of the two. I suspect the Curry grid crossings may still cause problems occasionally and I check for them just in case.

Much further research was generated by her pioneering work. To this day Salzburg has the lowest allowed emf levels in the world.
