Mermet Pendulum [VMB]

These are pendulums invented in the beginning of 20th century by Swiss monk Abbe Mermet, one of the fathers of modern radiesthesia. The main difference between other simple pendulums and the Mermet's is a hollow chamber used to place a "witness" - a small piece of mineral, water, hair, clothing - depending on what the operator is searching for. There are many variations of the basic Mermet pendulums.
