Shape: – With or without a sleeve handle. The top wire can be 4 inches to over 2 feet long. The usual length is around 12 to 16 inches.

Material: Usually wire. A metal coat hanger is a good source. Welding rod is also a very popular material. You can use 'use about any thing, you can bend into the L shape. The choice of brass apparently allows the rod to attune to the magnetic fields emanated by the target without the earth's EM field interfering, as would be the case with a metal such as steel. The end of the rod to be held by the dowser is often encased in a material that provides a constant electrical impedance, to prevent the dowser's own conductivity from interfering with the dowsing process. Some such rods also utilize a “witness chamber”, especially those claimed to be able to find minerals. The user places a sample of what he or she wishes to find in the witness chamber, usually located at the end of the rod, and the rod is supposed to only respond to the material placed in the chamber.

How to Use: Hold loosely one road in each hand, with the short arm of the L held upright, and the long arm pointing forward. When something is found, the rods cross over one another making an “X” over the found object, while they swing outward for the “no” response. If the object is long and straight, such as a water pipe, the rods will point in opposite directions, showing its orientation.

When one L Rod is used alone, it acts as a pointer or a swing rod. It can be requested to point towards a target or direction, or to swing sideways when encountering a specified energy field. (i.e. an aura or noxious zone.)

Advantages: Easy to make. Easy to use, very versatile and popular. Works well when walking over rough -round. They are generally not affected by mild winds.

Disadvantage: Not as easy to carry or conceal as a pendulum. Although the small 4 – 6 inch ones can be put in your shirt pocket or purse.
