In this blog post, we will guide you through everything you need to know about metal detectors, including how they work and what features to look for when purchasing one. We will also provide reviews of some of the best metal detectors on the market so that you can find the perfect one for your needs and budget!

What are Metal Detectors

Metal detectors are electronic devices used to detect the presence of metal objects. They work by generating an electromagnetic field that can pick up metals like iron and steel far below the surface

Most modern metal detectors use either Very Low Frequency (VLF) or Pulse Induction (PI) technology. VLF uses alternating current signals while PI creates short pulses of electricity. Both methods allow the detector to send out signals and pick up any metallic objects in the area, no matter how deep they are buried.

Metal detectors can be used to detect a range of metals including coins, jewelry, gold nuggets and other valuable items. They are also useful for locating lost weapons or tools in areas where visibility is limited. However, these devices are not 100% accurate as some non-metallic items may be picked up by mistake.

Metal detectors can be used to find all sorts of things, depending on your skill level and the type of detector you have. Some of the most common finds are coins, jewelry, relics, gold nuggets, meteorites, and even caches that have been hidden by other metal detector enthusiasts.

In terms of coins and jewelry, metal detectors can be very effective in finding items such as rings, earrings, necklaces, bracelets and other pieces that may have been lost or forgotten. Many people also use a metal detector to find old coins from different periods in history. In some cases they might even find rare or ancient coins.

Gold nuggets are another item that metal detectors can help locate. While it takes a bit more skill and patience to find these nuggets, you may have the chance to strike it rich with some luck and perseverance.

Just keep in mind that when treasure hunting with a metal detector, it is important to always follow the laws and regulations of the state or area you are in.[1]

Main Parts of a Metal Detector

To truly understand the working process behind a metal detector, it’s important to know what the main parts are. These are:

• Control Box – This houses all the electronics and controls for the device. It includes an LCD display that can provide information about what has been detected as well as adjustments for things like sensitivity and discrimination.
• Search Coil – The search coil is one of the most important parts of a metal detector. It’s essentially an antenna that creates a magnetic field around itself when it receives signals from the main control unit. When metal objects interact with this field, eddy currents are created which cause disturbances in the flux lines of the magnetic field produced by the search coil. This allows you to detect these objects even if they are buried deep underground.
• Shaft – The shaft is the part that connects the control unit and search coil to create an ergonomic design. Most metal detectors come with adjustable length so you can customize it for your height.
• Headphones – Headphones are an optional addition to most metal detectors as they allow you to hear audio signals while detecting metals. This eliminates the need to constantly look at the LCD display in order to know what has been detected, instead you can just listen for loud beeps or other noises that indicate something has been found.
• Stand – Many metal detectors come with a stand which typically attaches directly onto the shaft of the device. This helps keep your arms from getting tired when hunting for long periods of time as it provides extra support. It can also be useful for keeping your detector up and out of the mud or sand.

These are the main components of a metal detector, but there are many other features that come with modern detectors such as audio boost and pinpointing which help you narrow down exactly where a metal object is located. Now that you know about the different parts of a metal detector, let’s take a look at how it actually works. [2]

How Does a Metal Detector Work

Metal detectors use a technology called electromagnetism to detect metal objects. When an electromagnetic field is created around the detector, it creates a current that creates a magnetic field around the detector. The magnetic field will detect changes in the magnetic field when metal objects are close enough to interact with the detector. The strength of this field is measured in Hertz (Hz).

The sensitivity of the detector can be adjusted depending on how sensitive you want it to be and what kind of metals you’re searching for. Once something is detected, you’ll hear an audio signal or feel a vibration or see an indicator light to let you know something was found.

When a metal object interacts with the electromagnetic field, eddy currents are created which cause disturbances in the flux lines of the magnetic field produced by the detector. When this happens, the detector sends out a signal to alert you on what was detected. [1],[3],[4],[5]

Types of Metal Detectors

We already touched briefly on the different parts that make up a metal detector, but there are also different types of metal detectors available. The two main types are VLF (very low frequency) and PI (pulse induction).

VLF metal detectors

VLF (very low frequency) metal detectors are the most common type of metal detector. They work by emitting a low-frequency electromagnetic field which is then disturbed when it comes into contact with metals, resulting in an audible alert or vibration from the device.

VLF metal detectors use two types of coils: a transmitter coil and a receiver coil. The transmitter coil emits the electromagnetic field while the receiver coil detects any disturbances in this field caused by metallic objects. These signals are then sent to a control box and the user is alerted of any findings.

VLF metal detectors also offer users adjustable sensitivity, which allows them to more accurately pinpoint the location of buried treasure. By adjusting this setting, they can ensure they don’t miss out on any small finds that may have been overlooked due to their size or depth.

Pulse induction detectors

Pulse induction (PI) metal detectors are specialized metal detectors that use short bursts of high-voltage electricity to penetrate deep into the ground. The metal detector emits a powerful pulse of electricity and then listens for a response from metal targets in the ground. These types of detectors are often used by professionals, as they can detect deeper than other conventional VLF (very low frequency) metal detectors.

The PI technology works by sending out an electrical current which produces a magnetic field. When this field comes into contact with any metallic object, it induces a flow of electrical current in the target object, which is then picked up by the detector’s coil and amplified. This signal amplification allows PI metal detectors to detect objects buried much deeper than VLF detectors, as it reduces the amount of interference from other sources and improves the signal-to-noise ratio.

The downside to this technology is that it is more expensive than traditional VLF metal detectors, and PI detectors may struggle distinguishing valuables from metal scrap. As such, this type of detector is better suited for experienced treasure hunters who are looking for deeper finds.

Specialty metal detectors

Speciality metal detectors are specifically designed to locate certain types of metals and items. For instance, beach metal detectors are designed to search for coins and jewelry found in sand or water, while relic hunting models are intended to find historic artifacts buried underground. Each has their own purpose and is created with specific features meant to help you achieve your goals better.

Multifrequency metal detectors

Multifrequency metal detectors are a great option if you want to perform different types of searches. This type of detector utilizes multiple frequencies, which allows it to search effectively for different kinds of metals in various environments. It also offers more sensitivity so that you can find objects in deeper and harder-to-reach places. These detectors usually come with adjustable settings so that you can customize your search according to the environment and desired items.

Gold metal detectors

These metal detectors designed to find gold often have a higher frequency than other models and are capable of greater depths. Gold metal detectors generally include features such as ground balance, sensitivity control, and discrimination settings, which allow you to adjust the detector’s response based on the type of soil or mineral content in your search area. Depending on the model, some detectors also feature waterproof coils that can withstand being submerged in shallow water, making them ideal for searching rivers, streams, and beaches.

Waterproof metal detectors

Waterproof metal detectors, as the name suggests, are designed to withstand water. This is an important feature if you plan on submerging your detector underwater, like when looking for coins and jewelry on a beach or while diving in a lake. As the name implies, waterproof detectors can be submerged in up to 10 feet of water without any damage. However, they are not foolproof; they do not guarantee that your detector won’t be damaged by dropping it in deep water or using it in saltwater. [1]

Metal Detectors Buyers Guide

Now you’re familiar with the different types of metal detectors available on the market, as well as their key features. It’s time to figure out which one is the best fit for you and your needs. In this section we will discuss how to choose a metal detector, based on your budget, level of expertise, and what you plan to use it for.

Terrain

The terrain you plan to use your metal detector on is an important consideration when making a purchase. Different types of detectors are better suited for certain terrains and conditions. For example, if you plan to hunt for relics in wet sand or underwater, then an all-weather model would be best. However, if you’re going to explore shallow water, a standard model should work just fine.

Another factor to consider is the type of mineralization present in the soil or terrain. If there are high levels of iron present, then it’s best to opt for a detector that can handle iron-rich soils.

It’s also important to think about the type of objects you will be searching for. If you’re looking for coins or jewelry, then a smaller coil might be best. On the other hand, if you’re hunting for large objects like cannons, then a larger coil would be more suitable.

Your experience

You certainly won’t need to dump hundreds of dollars if you are just getting started, it is more important to find the right model for you and your needs than to buy the most expensive one.

For those with more experience, there are numerous high-end detectors on the market that have advanced features such as ground balancing and pinpointing technology. These models tend to be more expensive than their entry-level counterparts, but can make your search for treasure much easier and faster.

Weight

The weight of a metal detector is important for several reasons. First, a heavier metal detector is generally more difficult to carry around, making it less portable. Second, a heavier metal detector is also more likely to be damaged if dropped. Finally, a heavier metal detector may be more difficult to use for extended periods of time, as it can be more tiring to hold.

The weight of a metal detector also affects the depth at which it can detect objects. Heavier detectors are usually able to penetrate deeper into the ground, as their increased mass allows them to push through soil more easily and efficiently. In addition, heavier detectors are usually better for detecting larger objects, such as coins or jewelry.

Another important factor to consider when looking at the weight of a metal detector is the material from which it is made. Metal detectors made from heavier materials will generally be more durable and resilient than those made from lighter materials. This means they will last longer and remain in good condition despite exposure to harsh weather conditions or frequent use.

Finally, consider the body build and age of the user when choosing a metal detector. If you are an adult with a large frame, you may be better served by a heavier detector that can support your body weight. On the other hand, if you are a younger user or have a smaller build, then it is best to opt for lighter detectors that will not be too heavy to carry or use.

Size of the coil

The size of the search coil on a metal detector is important for both locating metals as well as discriminating between different types of metals. The larger the search coil, the more area you can cover with each swing but at a cost to sensitivity – which means it’s less likely to detect small items such as coins and jewelry. On the flipside, smaller coils are more sensitive but don’t cover as much ground in one sweep so you may need to go over an area multiple times if you want to ensure that you find everything.

The size will also affect the depth of detection. Luckily, many metal detectors come with adjustable coils so you can change the size depending on what you’re looking for and the ground conditions.

Depth indicator

Depth indicators are a key feature of metal detectors that can help you locate the best treasure caches and maximize your finds. Generally, most metal detectors come with some type of depth indication system- either a needle and scale readout or an LCD display. However, there are several types of systems available- ranging from a simple LED indicator to sophisticated digital displays.

The most basic type of depth indicator is a needle and scale readout. This type shows the approximate depth in inches on a linear dial. It is often used for coin shooting because it gives you an idea how deep your target is buried without any complicated calculations. But this system does not give much information beyond the depth reading; it cannot tell you what type of object is buried or what size it is.

Discrimination

Discrimination is one of the most important features of a metal detector. It allows you to identify specific metals in the ground and avoid false signals from other materials. This can help prevent frustration when searching for valuable objects, as well as helping to conserve battery life.

The discrimination feature on most detectors works by detecting the frequency or conductivity of a metallic object. Generally, more conductive metals are easier to detect while less conductive metals require higher settings on your discriminator dial.

Metallic targets such as coins have different frequencies than non-metallic targets like nails or bottle caps, so it’s important to understand how discrimination works in order to get the best results from your detector. A skilled user will be able to identify the different frequencies and adjust the detector accordingly.

In addition, some detectors offer more advanced discrimination features such as “Notch” or “Target ID” systems which allow you to precisely tune in a specific metallic target. This is especially useful for detecting coins or jewelry, as it allows you to eliminate false signals from other objects in the ground.

Sensitivity

Sensitivity plays an integral role in the performance of a metal detector. It determines how deep and wide the device can detect metals buried underground. This is because the required signal strength for detecting target objects varies depending on the size, shape, and composition of those targets.

In general, higher sensitivity will enable a metal detector to detect smaller objects at greater depths. However, this also comes with some risks since it increases the chances of false alarms due to other electromagnetic interference or “noise” such as electrical generators and power lines nearby. Therefore, it’s important to understand your environment before setting up a machine with high sensitivity levels.

Ground balance

A metal detector’s ground balance is an important setting that allows the machine to efficiently locate metal objects, such as coins and jewelry. Ground balancing helps eliminate false signals from environmental factors like minerals in the soil or black sand. It also helps prevent interference from other nearby metal detectors.

When you are out hunting for buried treasure, there may be a large variety of variables that could throw off your ability to find what you’re searching for, from chemical content in the soil to electromagnetic interference from nearby machines. By understanding how ground balance works and properly adjusting it on your metal detector, you can create a more consistent search environment and increase your chances of finding hidden items.

The primary purpose of ground balancing is to negate any false signals that a metal detector may receive from its environment. When the ground balance is set correctly, the machine will be able to differentiate between non-metallic and metallic objects in the area. This allows you to more accurately locate any items of value beneath the surface.

Certain mental detectors are better at ground balancing than others. If you plan on doing a lot of detecting in areas with high mineral content or black sand, you may want to consider a model that features automatic or tracking ground balance. These models will continuously adjust the ground balance as needed, which can save you time and frustration in the field.

Frequency

The frequency of a metal detector is the number of times per second that its coil sends out an electromagnetic signal.

The higher the frequency, the better it is for detecting small objects like coins and jewelry. Low frequencies are better for large metallic objects such as silverware, relics and treasures buried deep underground. Generally, the lower frequencies penetrate deeper into the ground while higher frequencies offer greater sensitivity to smaller targets near the surface.

There are several factors that can affect how well a detector works at a particular frequency, including the size and shape of the coil, the type of soil, and the presence of other metal objects

Your budget

Let’s face it, metal detectors can get pretty pricey depending on the features they offer. Before making a purchase, consider setting a budget that you know you can afford. This will help narrow down your options and make it much easier when deciding which detector is right for you.

The good news is that there are many affordable models available with great features. You don’t have to spend thousands of dollars just to get started in this hobby. Do some research and read reviews before making any sort of commitment to ensure that you’re selecting the right device for yourself! [1],[3],[4],[5]
