Metal Detecting is where participants use metal detectors to find metallic objects. It is done for both recreation and sport.

Metal detectors were first introduced at the end of the 19th century. After World War II, a hobby was created around using metal detectors to find hidden objects in the ground. Today technology has greatly improved, allowing for much smaller and better-hidden objects to be discovered.

Use a metal detection device to search for and discover hidden objects in the ground.

One should always seek permission from the owner of the land which is being searched. Some public lands may require permits from local officials. Rules and restrictions regulating the reporting and documenting of found items vary. One should always review these rules (if any) prior to searching.

Metal detectors were first introduced towards the end of the 19th century, and were primarily used in mining. These devices were unreliable, cumbersome and limited by short battery life. Modern devices began to appear in the 1930's. During World War II, metal detectors were used to clear minefields. After the war, a surplus of these devices helped create the modern day hobby of metal detection. Today, devices are lighter, more sensitive and more powerful than ever before. This has allowed for even the most novice individual to excel at metal detection.
