Dowsing has been implemented successfully in Sri Lanka for identifying well sites, yielding significant economic benefits and prompting further scientific investigation into its efficacy. A study led by GTZ and involving multiple institutions confirmed that a dowsing expert demonstrated statistically significant success compared to others. Despite skepticism and the lack of a scientific explanation for how dowsing works, practitioners report consistent results in locating underground resources. Discussions highlight the need for rigorous testing to validate dowsing claims, with some suggesting that the technique may be linked to sensing disturbances in magnetic fields. Overall, while dowsing remains controversial, its practical applications in fields like geohydrology are increasingly recognized.
