The Bovis scale
, allegedly named after a French radiesthesist
called either Antoine or Alfred Bovis (1871-1947), is a concept used by dowsers
and adherents of geomancy
to quantify the strength of a postulated "cosmo-telluric energy" inherent in a location. The unit of the Bovis scale has no known definition and isn't in any way based on physics. The "measurement" consists of the dowser walking around the place with an object (like a pendulum, dubbed "biometer") and declaring the Bovis number. A number of 6,500 is considered "neutral", lower figures affect human "energies" negatively, higher numbers positively. Numbers above 10,000 are in the "ethereal range", considered Places of power
