Treasure hunting is a popular pastime and hobby for thousands of people. The thrill of the hunt combined with the occasional success makes it an addictive way to spend the weekends. For these weekend warriors, ground search metal detectors can be an invaluable tool.

Ground search metal detectors are hand-held devices that allow the user to "sweep" the immediate area in the search for small, valuable metal objects. Coins, rings, and even raw gold are commonly found by using these detectors. Depending on the amount, as well as any historical significance, these items are often worth a great deal of money.

Most metal detectors work according to Lenz's law of electromagnetism. Simply put, when a conductor (coin, ring, or other metal object) comes into contact with an alternating magnetic field, it will create an opposing field of its own. The changes this opposing field creates in the overall electromagnetic field is picked up by a magnetometer, which then sends a signal to the operator indicating the presence of metal. The accuracy of the metal detector depends on the quality of the detector itself, as well as the environment in which it's being used.

Coin hunting is one of the most popular applications for ground search metal detectors. Coin enthusiasts can often be seen combing the beaches searching for lost treasure. While most of these coins are rather benign, there are plenty of examples of rare, highly sought coins being found through the use of these detectors.

Historical sites are also very popular with amateur treasure hunters. Ground search metal detectors are often used to locate relics from the past, and with great success. Civil war era bullets, military dog tags and medals, and even colonial era coins have all been found at locations across the country.

Metal detectors can most easily be purchased through the internet. Simply typing in "ground search metal detectors" or "metal detector dealers" can reveal a host of resources. The cost of these devices can range quite a bit, with inexpensive models starting around a hundred dollars and going well over a thousand for a top of the line version. However, for the average weekend warrior, most models on the low end of that spectrum will suffice.
