Jewell Drilling Services specialise in Water Divining, sometimes called Dowsing, a method of locating water underground.
The most well known gesture of the dowser is that which consists in holding a hazel, almond or will stick in one’s hands, and to advance over the ground, the stick forming a V and by exerting a light pressure to maintain it parallel to the ground.
When the dowser passes directly over a bank, or underground river, the rod will react and either drop or rise upwards (depending on the person holding it). A good dowser can find the banks, width, direction of the current, its depth as well as its flow rate. With practice the dowser advancer over the ground, holding his diving rod firmly (but not too tightly) in his hands, these rods can be any of the following materials, plastic, hazel, willow, almond, steel brass or even whale bone.
He advances slowly, exerting a light pressure to maintain his rod stable and parallel to the ground, fingers closed around the rod, and palms turned upwards. When passing directly over a bank, an underground river, the rod of the dowser will be raised and remain raised, (or drop and stay down, depending on the person using the rod).
For as long as he walks over the underground river, and will drop when he comes to the other bank. This is how he will be able to determine the width of the banks by placing stakes at the beginning and end of the rod movements.
