The dowsing rod is a tool known to mankind for a very long time. Various cultures have used dowsing rods (also known as “divining rods”) to find the location of things such as water and other natural resources beneath the surface of the earth.
There are many types of rods plus some variations even with the same type, which makes them more applicable to certain energy fields.
They all have one common purpose however - they are used to detect or search for vibrations emitted from an outside source. As such, they are a receivers of vibrations as opposed to the ability to generate vibrations.
Some rods have a “witness chamber”, which increases their sensitivity when a sample (witness) of what is being searched for is placed on it.
