Treasure Hunting With A Metal Detector

Ever wondered what treasures might lie hidden right beneath your feet...old coins or jewelry lost long ago, just waiting to be picked up by a passerby like you?

With a cutting-edge metal detector, you'll be equipped to discover precious objects lurking right underfoot. And you may discover that your fun new hobby also turns out to be an extremely profitable one. Metal detectors have long been popular with beachcombers, hikers, coin collectors, and treasure hunters, since they can turn any outdoor outing into an exciting treasure hunt with just the flip of a switch.

A variety of hand-held metal detector models are available, ranging from basic designs for the beginner to highly advanced detectors used by professionals and serious treasure hunting hobbyists. Prices range equally widely, from under $100 to well into the thousands of dollars depending on the sensitivity, precision, and depth penetration of the metal detector.

If you're shopping for a metal detector, it's a good idea to begin your research by checking out models from leading detector manufacturers, which include White's, Garrett, Bounty Hunter, Minelab, Tesoro, and Fisher.
If you're just getting started on a treasure hunting hobby, there's no need to splurge on the most powerful, fanciest model - but you should make sure that it offers the option to discriminate between different types of metals, so you don't waste your time digging up paperclips and nails all day.

So how do metal detectors work, exactly? The core technology at the heart of most metal detecting systems involves generating an alternating electromagnetic field via an electric oscillator coil. This field causes (or induces) any metal objects in its vicinity to generate their own magnetic fields, which the detector then identifies with a built-in magnetometer.

If the magnetometer detects that an anomalous magnetic field has been induced by the oscillator, the detector generates a tone or provides a visual display to let the operator know there's possible treasure in the area. Metal detectors also have serious security, military, and construction applications.

Specialized models are used for detecting mines and hidden weapons, and for security screening at airports. If you've ever traveled by air, you've undoubtedly passed through a metal detector checkpoint, which includes a scan by a walk-through detector and often an individual screening with a hand-held wand detector as well. In the construction industry, metal detectors are used to locate underground pipes, cables, and other metal objects on a building site.

Once you've done your research and decided on the metal detector that works best for you, you'll have trouble finding a great deal on a new or used model at shopping sites like Amazon and eBay. With plenty of reputable online merchants to choose from, your new metal detector is just a few clicks away!
