Metal detecting has a long, and often strange history. Interest in using electrical current to locate buried metal began in the late 1800’s. At that time, people understood that certain metals somehow interacted with electrical currents, though it was unclear how this worked. The first attempts at metal detection were aimed at finding rare metals, like gold. Unfortunately, the results were not always what buyers hoped for. In another bizarre twist, the inventor Alexander Graham Bell attempted to used metal detection to find the bullet that had become lodged inside President James Garfield. Though it seems simple enough, Bell’s machine was too powerful and kept returning a signal for the metal bed frame on which the president had been laid.

The 1930’s saw the arrival of new technology, particularly the use of radio waves as a navigational tool. Metal detectors were redesigned and could now provide a more accurate picture of any buried metallic item. Metal detectors became a crucial part of the war effort during World War II, helping to identify buried landmines and other dangerous items. At the end of the war, excess metal detectors were sold to the public, and metal detecting as a hobby really began to take off.

The modern commercial metal detector is easy to operate and usually calls for little or no assembly. A convenient manual included with the device will offer maintenance and operation information for new users, so read it carefully before you get started. You will want to keep it to refer back to later.

Getting to know your detector will take time and practice. The best way to get to know your units tones is to practice at home with it first. Set up a practice course using a variety of objects like plastic cups and lids, loose change, pan lids and random items. You can walk through “finding” things until you get used to the way certain items sound when your detector signals.

Metal detectors are selected on the basis of the terrain on which they will be used. There are several varieties of machines on the market. Pulse, single- and multi-frequency devices, as well as long-range machines are examples of the different kinds of detecting devices that are available to the consumer. o Possessing the greatest range, pulse detectors, however, don’t discriminate well between junk and treasure. o The best machines to use in zones with a minimum of moisture are multiple-frequency detectors. o Able to detect significant objects buried 20 feet beneath the surface, the expensive long-range detectors are preferred by professional treasure seekers.

If you research your selection, the reward can be enormous. Don’t forget to check in with the online metal detection enthusiasts, they have years of experience and are glad to share. Happy hunting!
