Discover New Treasure With A Metal Detector

Metal detectors are used for various reasons. Most are hand-held and operate with a coil that oscillates a current when a metal substance is close enough to the coil a signal is sent alerting the person. The first metal detectors were used in the 1960's for mining and industrial purposes. Metal sensors are now used for everything from finding precious metals to airport security. There is no harm in using a metal detector because the coil does not produce radioactive waves; it only emits them when a metal object is close enough to the surface.

The military often uses double coils when searching for explosive devices.

If you live near a beach you might see a person walking around with a metal detector, they are scanning the beach area for hidden metals. People often bring to the beach things they should I have at home such as rings, watches, earrings and such. Loose coins from a pocket or change purse can also trigger a metal sensor. A gold detector works much like a metal detector; it uses a coil that sends a signal to the user that gold is close enough to the surface to be unearthed. Gold detectors vary in price and are considerably more expensive than a metal detector.

Many of the detectors are light-weight and can be carried by right and left-handed persons. A long rod with a coil attached at the end is used to scan areas while walking along so that you don't have to bend down if your metal detector does alert metal you can use a mesh scoop for sand exploration. A wrist harness helps to hold your metal detector just above the surface of the area you are scanning. You can even use a metal or gold detector in water. Headphones are used to drown outside noise away so you can hear the signal designed to let you know that metal is close by.

There are different sizes of coils, depending on the area you are covering; a larger coil will scan more ground. You can even buy an amp cover to keep your coil from getting damaged. The coils on a detector are not like exposed coils on a range store, they are housed in a plastic covering that resembles a satellite dish. They are called elliptical search coils. You can buy accessories for your gold detector such as a digging trowel and a carry bag in case you find any gold or metal.

A great metal detector should have basics to fit the treasure hunting activity you plan to do. If it's intended for children to use, choose detectors that are very light in weight and need no setting adjustments. These metal detectors for children can identify objects with two different audio tones emitted upon detection. The low tone is for poor quality metals and the higher tone for better coins and other higher quality metals.

The batteries that are used with detectors can be charged at home on a standard AC current. You can even buy a car charger if you are going to be traveling to different areas and will not have access to electricity. Jewel hunters often buy the best equipment so they can maximize their search potential. Some metal detectors have depth coils that can detect deeper underground than standard metal detectors.

Not only can you find gold, metal and some neat relics left behind but it's also great exercise since you will be walking while enjoying your hobby.

The more advanced may have special features fit for your treasure hunting activities or for a job. There are some that have LCD indicators for the specific focus and depth, 4 levels of metal discrimination and some even have special features to reject low-value metal targets. Even with many different, unique features, metal detectors are affordable and even come with warranties. You can easily find great reviews of metal detectors online. If you are new to buying them, it is strongly recommended that you look for ones that are for beginners to use. The ones for beginners do not have many features, but they are very easy to use on their own and not many settings are required for you to adjust. You should purchase them online as they have many competitive prices and some will even offer you free shipping to help you save more money.
