Buying the right detector can be an overwhelming and daunting task since there are many brands and options, among other factors to consider. The purpose of this guide is to educate you on the core basics of metal detectors and how you should go about choosing the best detector that suits all your needs. In the end, you'll also find that beginning metal detecting as a hobby is such a fun and cool activity to do.
What to Look for When Buying a Metal Detector
What is a metal detector?
A metal detector is simply a portable electronic gadget that digs the ground magnetically in search of a metal substance. People usually find all sorts of things buried in the sand ranging from junk materials, gold, jewelry, coins, or historical relics. The premise that somebody can come across a hidden treasure or a valuable material stuck underground is something that appeals to many. Some of the most common places people usually hunt for these materials include parks, beaches, farming land and more. Nevertheless, even after spending many hours searching for treasure, many people end up digging up a heap of trash. It's important to choose a detector that has the capability of distinguishing whether the material stuck underneath is a treasure or trash to avoid wasting time.
How does a metal detector work?
The theory on how all metal detectors work and function is based on pure electromagnetic and reaction of conductive metals. A metal detector uses battery charge to channel a penetrating magnetic field that digs the ground. Consequently, any metallic material hidden in the ground gets charged through magnetism, which ends up sending a sound signal back to the detector. The device also informs the treasure hunter what kind of metal is underneath and the length or how deep the metal is (usually in high-end units).
Most metal detectors can trace metal substances stuck like 1 foot below the surface. More advanced ones can penetrate even much deeper, depending on their specific ferrous and conductive properties. Conductive properties purpose is to substantiate how a metal conducts electrical current and how it responds to the device magnetic field. Materials like nails and foils have different conducive properties, compared to items such as coins and rings. As such, the detector can simply tell whether the metal substance stuck underground is trash based on its conductivity.
Ferrous properties purpose is to measure the amount of iron in a metal substance or target, which makes it easy to tell how strong that specific material is attracted to a magnet. Many times, targets or metal materials with a ferrous property are usually trash, thus making it easier for treasure hunters to ignore them based on this analysis alone.
Components of a metal detector
All metal detectors bear similar parts in spite of their brand or model. Below are some of the main components of a metal detector.
Actually, this is an arm brace whose primary purpose is to support the unit moving back and forth on a surface.
The shaft simply attaches the search coil to the devices control box. It's usually adjustable, which means you can tweak it to any height level you wish.
3. Control box
This is essentially the detectors brain and consists of a speaker, batteries, circuitry, microprocessor, and some controls. Some devices may also have a jack for headphones.
4. Search coil
And finally, the search coil is the actual component that usually senses the metal substance underneath the ground.
Factors to consider before buying metal detectors
Don't buy this gadget merely on another person's advice or recommendation, neither should you purchase the device based on its brand name and model alone. Nowadays, metal detectors exhibit more new features essential to the quality and how such a machines function. Before you decide to buy this electronic gadget, make sure to make an informed decision by giving careful consideration to some of the few factors listed below.
Metal detectors vary in price, depending on the specific accessories a device bears. The more accessories a device carries, the higher the price is for that particular gadget. If you wish your detector to have more accessories like headphones, digging tool, or a carrying bag, at least ensure you have a proper budget in place. It's also important to make sure that you buy a device that would yield you huge benefits long-term.
If you choose to use the gadget many hours in a week, at least get one with more extra electronic features than the one you'd use only for a few hours. The more attributes your device carries, the more you'll enjoy using the detector. You'll also find it easy and fun to use for long hours!
Do you hang around the beach more often or shelter near a water source? Regardless of brand, all detectors bear water-proof search coils. This means it's easy to hunt for jewelry and coins or any other metal substance from virtually anywhere-shallow water, river, beach and so on. Nevertheless, not all metal detectors can be fully immersed underwater, so be sure to check its features and use before you place an order.
A person's skill level in metal detecting matters a lot. If you lack in experience, it's best you start with an entry-level gadget. Even though it won't bear all of the enhanced features, you can be sure that it will pick and sense any metal substance hidden underneath just like any other device. Beginner-level metal detectors are also considerably cheaper, compared to those that bear more additional features and enhancements. At least this would get you more bang for your buck, which is awesome!
Metal detecting is becoming more and more popular every day. Apart from hunting treasure and other valuable metal substances underneath the ground, many also find metal detecting as a fun hobby and a means of entertainment. Use this guide all the time anytime you want to buy a high-quality metal detector that matches your specific taste and the intended purpose. All the same, if you're buying the device for a teen or a 10-year-old, ascertain it has a smooth control gear for much more convenience.
