Left: This is a brass replica of the pendulum used by Abbe Mermet, a founder of modern radiesthesia. It is a popular tool with homeopaths as the cavity can hold a sample for transmitting distances. 1 1/4″ long.
Middle: Hollow Plexiglass witness, often used for minerals. The plexiglass minimizes the influence of the pendulum’s own material. Can be used to energize small materials such as gemstones. 1 1/2″ long.
R: Double Mermet. It is more sensitive than the single Mermet, further amplifying the energy of the sample. It responds well to mental commands. 1 3/4″ long.
