Glossary of Dowsing Terms G-M

Gardner Rosette

A combination colour witness and percentage chart developed in 2016 by G Gardner. It includes the traditional 8 colours of the Mager Rosette plus an additional 6 colours of brown, pink, light blue, gold, silver and copper that are useful in Earth Energies and mineral dowsing. The central area contains a plus/minus percentage pendulum chart for further classification.

Geodetic Line

Guy Underwood in his book ‘The Pattern of the Past‘ coined the term “geodetic line” to embrace three different types of line which, he states, form a complex network on the earth’s surface. He named the types Water Lines, Aquastats and Track Lines, and reported that each consisted of groups of three parallel lines which he named triads. According to Underwood geodetic lines converge at Blind Springs but are not the same as energy leys for they do not always run straight, but may meander, loop or spiral.

Geodic Faults

Cavities in igneous rocks which are partially filled with minerals in the shape of well-formed crystals. These can emit unique forms of energy that can have various effects on the biological system, beneficial and detrimental.


A picture, diagram or shape found in the energy field by dowsing. These are formed by a single convoluted line of subtle earth energy (first found by C Bloy and investigated by H Miller who called them pictograms). Some more complicated forms that can be observed are similar to those found in rock art and landscape figures throughout the world and have also been termed ‘archetypal images’ by W. A. Gawn.

Geological Fault

Major fractures in the rock structure of the earth’s surface that create stress when relieved this causes earthquakes. These faults emit energies that are generally considered by dowsers to be detrimental to most forms of life.


The art of placing structures on the landscape so that the earth energies enhance their use and the structure itself is in harmony with the earth.

Geopathic Stress

An unfavourable reaction of the biological system as the result of exposure to radiations from the earth that would be dowsed as detrimental.

Geopathic Zone

An area of the Earth’s surface that emits energy that is detrimental in nature and likely to cause geopathic stress in any life form exposed to it.


A name given by Guy Underwood to dowsable spiralling energy patterns commonly associated with Blind Springs and Power Centres. These may be found with varying numbers of turns up to a maximum of 49, and frequently have a ring of smaller S-shaped bands outside the main spiral.

Like many Earth energies, Geospirals are affected by moon phases.

Golden Mean

The basic ancient sacred geometric ratio of 1:1.618… The Golden Mean is often found in nature and has been utilised extensively in the construction of early sacred and religious sites. Two quantities are said to be in golden proportion if the ratio of the sum of the quantities to the larger quantity is equal to the ratio of the larger quantity to the smaller one. The square root of the Golden Mean, 1.272…, has also been widely used in design and construction. A building constructed incorporating the Golden Mean in its design is unlikely to contain detrimental energy.

Hartmann Grid

The Hartmann grid is an earth grid named after Dr Ernst Hartmann who it is thought was the first to observe earth grids. It is a worldwide grid in accordance with the earth’s magnetic field, i.e. approximately N/S, E/W. There are considerable variations in the grid spacing dependent on local conditions and the degree of latitude. In Greenland a spacing of 1.05m x 1.20m is found. In England the average spacing is 1.60m x 1.68m while in the Canary Islands it is 2.00m x 2.50m. The straightness and orientation of the grid lines can be affected by building geometry, high voltage power lines and radio stations etc.

Information Dowsing

Where dowsing is used for gathering information about the subject under study, e.g. the depth or quantity of an underground flow of water.


A term often used by dowsers and healers to denote the relative effect of an energy on an object or living system, usually in arbitrary terms. Healers often feel the intensity, and dowsers measure it using various scales such as 1-100. A well-known instrument for measuring this is the Bovis Biometer.

Juvenile Water

See: Primary Water.


A form of muscle resistance testing which can be used to identify whether different types of energy are detrimental or beneficial to us. One of its uses is to detect allergies and the health of the human body.


A significant alignment of sacred and secular sites across a landscape, generally inter-visible. The minimum number of aligned sites to qualify as a ley is five. The term was first used by Alfred Watkins in 1921. Watkins never used the term ‘ley line’.

There is no associated energy line indicated by the term ‘ley’ as Watkins described it, and therefore it is not to be confused with an Energy Ley.

Ley Line

The term used (incorrectly) by many dowsers to describe an energy ley, a straight line of energy that may link ancient sites where it coincides with a visual ley. It is easily confused with the term ley, which is a purely visual alignment, and therefore its use is not recommended by dowsers. It is also commonly used indiscriminately by the public in general. Alfred Watkins never used the term ‘ley line’.

Life Force

Can be used to describe the energy within a field around an object, e.g. earth energy is the life force of the Earth. The human aura is the life force of the human. It is considered that the life force which manifests itself around an object comes from a greater source.

Long Pendulum

A pendulum of which the cord is adjusted in length until a response is felt. The length of the cord at which the pendulum responded could identify every substance. The string is usually stored wound round a spindle of some sort so that it can easily be unwound to the desired length. Lethbridge claimed that lengths under40 inches related to life forces, and lengths beyond 40 inches related to dimensions beyond death. His conclusions are regarded as controversial by most dowsers. Sub-classifications are defined by counting the number of gyrations or oscillations. However, the length, or rate, relating to each substance has been found to be unique to each dowser. (First used by T. Lethbridge)

Mager Rosette

A disc divided into eight coloured segments. The colours of the segments, going clockwise, are black, white, purple, blue, green, yellow, red, and grey. It is traditionally used in water dowsing to establish water purity, but may also be used in energy dowsing to identify differences in energy types so that the dowser can distinguish more accurately between one energy line and another. The colours are held one at a time between finger and thumb of the free hand whilst dowsing. Invented by the celebrated French dowser, Henri Mager.

A dowsable symmetrical pattern found at a power centre or the crossing (or node) point of two or more significant earth energy lines. Usually produced by conscious interaction with the site. (first mentioned by H Miller).

Map Dowsing

A method of dowsing using a map, or drawing, instead of or before visiting the site. This can be done using a pendulum in one hand whilst pointing at the map, or drawing, with a pencil in the other hand. When the target is found the pendulum will swing in the affirmative. However, many other techniques are used successfully. Map dowsing is done prior to a site visit and will reduce the time spent on site.

Any method by which a rule or calibrated instrument, frequently on a scale of 1-100, is used to determine the quality, rate or vibration of an object. It can be also done by counting in whatever measurement is most suitable until a positive dowsing response is felt. In many applications measurement will greatly assist the dowser.
