How many can remember the early metal detector craze back in the mid-to-late 1970s? No? Well it happened. And it was fun. Many backyard prospectors, as they were later dubbed, took to the beaches, parks, roadsides, battlefields, or wherever else metallic relics of the past could be found. And in fact, millions of historical pieces, such as coins, bullets, knife blades, etc. were lovingly retrieved from their earthen graves; not to mention countless pull tabs and soda can remnants. It was all great fun. Still is! Which is why metal detectors are still very popular and continue to intrigue the amateur (and professional) treasure hunter in all of us.
So, what is a metal detector? In short, they are electronic devices designed to locate minute to large amounts of metal buried under the surface of the ground or simply just out of plain sight. Detectors are able to trace metallic remnants through a variety of material, including, but not limited to: soil, clay, wood, brick, and so forth.
Now, you might ask: How does a metal detector work? The answer is simple science; electromagnetism to be exact. The design premise is simple. The sensor gives off a magnetic field, typically produced from an connected electric battery, and when some trace of steel makes contact with the actual electromagnetism, a little magnetic circuit is done and a signal sent to the actual detector's transmitter. This signal is subsequently amplified resulting in a beeping or buzzing sound. If this sounds like basic science, then you'd be right. The actual strength associated with the sensor is actually primarily determined by the quantity of electro-magnetic present created as well as how delicate the actual on-board transmitter as well as amplifier tend to be.
Detectors come in a variety of sizes, power, and function. For example, there are detectors uniquely designed for underwater use as well as for prospecting certain types of metals such as gold. Whites metal detectors, one of the world's finest manufacturers of detectors, offer such models. Other detectors are designed for beginners and younger-aged prospectors. Bounty Hunter, for example, also manufacture a few of these models. For the more experienced treasure hunter, there are various multi-purpose detectors available with a wide range of strength and sensitivities.
In conclusion, even though the interest in metal detecting has been around for many years, the fun and excitement created by using these electronic wonders is ongoing. Get into the hunt today and purchase your own metal detector. Who knows what may be hidden in your own back yard?
