Finding Metals Made Easy and Fun!

Metal detectors are of those devices that not many people know that they have multiple purposes and uses. We often just see the metal detectors installed indoors at the entrance of malls or airports. But the handheld metal detectors are even more common because they are not only used for protection but for a lot of other tasks as well.



Metal detectors that are handheld consist of a search coil that is able to detect any hidden metal at the place where it is kept. By detecting a metal nearby, you can find out useful metals for use as well as harmful metals to be ignored or destroyed.



Why Give Metal Detectors A Chance?


Using metal detectors is also a hobby by a majority of the people who use it. For families who want to go hunting for coins, jewelry, or gold pieces, this is ideal equipment that will help them enjoy and spend quality time with their family at the same time.


Adjustable length in many of them makes them suitable for adults as well as kids. There is no restriction regarding the age of kids either. Everyone can enjoy hunting for exciting things without being at any risk. When they are used for commercial purposes or for mining, it is imperative to choose metal detectors that can go deep into the ground. Similarly, to experience finding metals in water, they should be able to get submerged without any damage.

What Should You Look For When Buying A Metal Detector?

You can purchase a metal detector for actual use and then also keep it for such recreational activities as well. To be able to choose a metal detector you need to know a few things. Who exactly will use it? Are you going to look at places that will need separation between the needed and unwanted metals? Do you know which detection modes you need?

It sure is difficult to select a brand and a model when so many technical details are involved. Especially if this is your first time buying a metal detector, you don’t want to get impressed by a single review of a model and choose hastily. If you are serious about getting one, you would need serious research.

There is a wide range of prices between which different models lie. You shouldn’t spend on features that are not essential for you. On the other hand, you also shouldn’t get something so basic that you are not able to enjoy it to the fullest later on. If you trust us, we won’t let you waste your money.

If you are still confused about whether you should purchase a metal detector or not, you should definitely read more about it and ask yourself what is stopping you from having this unique experience. Don’t let your fear and your confusion stop you from doing something that you really want to do.

Always Think About…

Depending on how accurate you want your results to be, always think about the sensitivity level before purchasing a metal detector. The sensitivity level will determine whether you will be able to find metals easily or not. For crucial purposes, always choose a metal detector that is the most sensitive.
  • Since you have to handle the equipment and pay attention to any signals of metals found simultaneously, you need a metal detector that you can carry conveniently. For that, always think about the weight of the metal detector that you are going to buy. The lighter, the easier to carry.
If you wish to find metals underwater, always check if the metal detector that you are planning to buy is waterproof or not. Some metal detectors are entirely waterproof and can be completely submerged into water. Others are partially waterproof and even though the search coil can be submersed, the handle cannot. It totally depends on your application which one of these you would want to get.
As you would have already noticed, we have detailed insights about metal detectors that you probably did not know beforehand. Our guide is comprehensive and would most definitely help someone who wants to make an informed decision. So don’t change your mind after reading all this, in fact, finalize that you will purchase the perfect metal detector for yourself after taking assistance from our guide.

Metal Detector Buyer Guide

Most consumer-grade metal detectors use an older technology called VLF (very low frequency) detection. A VLF metal detector uses two related forces, electricity and magnetism, to generate an audible signal when something is detected.

How it works

A metal detector’s circular base contains two wire coils: a larger transmitter coil and a smaller receiver coil. When the user activates the detector and begins a sweep, the electricity from the battery flows into the outer transmitter coil, creating a ground-penetrating electromagnetic field. Any metal object that receives this electromagnetic charge becomes “excited” at an atomic level. In a sense, the outer transmitter coil creates a magnetic “glow” around metal objects.
Once the transmitter has “excited” any metallic objects in the ground, a smaller receiver coil takes over. This coil looks for any changes in the charged ground’s magnetic field. Metal objects send out a second magnetic current in reaction to the transmitter coil’s energy. This change in magnetic polarity is what the receiver coil actually detects. A signal is sent to a loudspeaker, which issues a tone based on the characteristics and strength of the charged metal.


Many high-end metal detectors also contain a microprocessor-controlled analyser known as a discriminator. A discriminator compares the signals sent by the receiver coil to the known signals of various metals. For example, the typical gold signal is noticeably different than the typical aluminium signal.
A discriminator can be set to squelch signals from common “junk” metals, such as steel and aluminium. This allows the user to concentrate on more valuable metals that could be lurking underground, such as gold and silver.


The models on our shortlist offer various search parameters based on their intended audience. After all, a child searching for quarters on the beach has different needs than an adult treasure hunter in the field.


Here are some questions to ask yourself when evaluating different products.

What is the metal detector’s coin depth?

This is a measure of how deep underground the device can actually detect coin-sized pieces of metal.

Is it waterproof?

Some metal detectors are completely waterproof, for depths down to 3 metres.

Others have waterproof coils but can’t be completely submerged. Users should never submerge the electronic parts of these devices. Some cannot be used near water at all.

How big are the coils?

Arguably the most important thing about a metal detector’s coil size is the amount of ground you can cover. The challenge with small coils is that if you sweep too quickly, you could miss things. Larger coils help to eliminate this. However, smaller coils can help pinpoint objects.

Some metal detectors will have both coils so they can do both jobs.


When it comes to informational displays and other features, big differences exist among the metal detectors on today’s market. When considering a purchase, look for these special features. Granted, some of them may not appeal to you, but it’s nice to know what you’re buying into.

Volume knob

Your metal detector will beep frequently. If you’re interested in controlling the volume, you’ll want a volume knob.

Headphones/headphone jack

Metal detecting is a somewhat noisy hobby. If you’d rather keep your business to yourself, look for a detector with a headphone jack. Some products include headphones, too. But remember, the price of a complete kit is higher than the price of a lone detector.

Sensitivity knobs

Many metal detectors offer a range of sensitivities, which you can adjust to filter out junk and focus on what you’re looking for.

LCD screen

Some basic models do not have an LCD screen, but such an interface is a great place for the user to gather information.

Ground balancing

This feature gives you the ability to “tune out” interference from natural metals in the soil (like iron).

Custom notching

Notching is a lot like discrimination in that it allows the user to filter out some unwanted results. However, a bad notching system could lead to missed findings.

Where you can hunt

With all of these rules and limitations, you may be wondering where you can actually use your metal detector lawfully. In truth, there are still a number of locations open to hobbyists. The key is to find places where people have actually lived, worked, or played. Consider these areas:

  • *Schoolyards
  • *Old home sites
  • *Former factories
  • *Beach fronts
  • *Amusement parks
  • *Recreational lakes


If you’re going treasure hunting, you need a machine that’s comfortable for you to use over the long haul. Look for these features to find the most ergonomically sound metal detector for you

Adjustable length

The length of some metal detectors can be adjusted based on the arm size of the user.


How much does the metal detector of your choice weigh? It may seem like a small matter, but if you’re planning to spend an afternoon waving the detector around, you’ll probably want something that doesn’t strain you. Anything around 1.8 kilograms will work best.


Before you go treasure hunting, be sure to understand the correct settings and capabilities of your metal detector. Read through the manual and research online, if needed.


Like golf, metal detectors require a proper swing to work well. Swing your detector slowly from side to side, keeping it as close to the ground as possible — but make sure it does not touch the ground.


Similar to having the right digging tools, your choice of clothing is important when you’re on a hunt. Wear comfortable clothes that are appropriate for the weather, knee pads to protect your knees when you have to dig, shoes that help you wade through terrain, and gloves for your hands so you don’t get them dirty or cut yourself when scooping up soil.


Educate yourself on the local laws regarding metal detecting before you start. That way, you know which areas are permissible and what kind of digging is allowed. Remember, even public areas may not allow metal detecting if they have landscaping that could be damaged.


If you’re new to this hobby, be prepared to find more trash than treasure. But don’t lose hope, as you never know when your luck may change. That’s part of the excitement and appeal of metal detection.


Q: How deep will a typical metal detector penetrate the ground?


A: The answer to this question depends largely on the detector’s make and model, but in general, the average detector can find larger pieces of metal 30 to 45 centimetres below the surface. Deeper searches would require a more powerful device, such as a ground-penetrating radar.


Q: Do I need a special kind of metal detector to hunt for gold?


A: While most metal detectors can detect the presence of gold in a general sweep, many discriminators have difficulty tuning out other metal signatures. This is why dedicated gold hunters often purchase a special metal detector designed to “listen” specifically for smaller gold fragments.


Q: Metal detecting seems very straightforward to me. What do the pros know that I don’t?


A: For one thing, experienced hobbyists and professionals use several different types of sweeping and search patterns, not just a simple back-and-forth or up-and-down motion. Through experience and mastery, they can tell the difference between valuable metal hits and “trash” hits by the subtle changes in signal tones. Mastering the art of metal detection takes time, patience, and practice.
