What is a Metal Detector?

A metal detector is a device that helps you discover metal objects below the ground. In other instances, you can also use a metal detector to find lost metallic items such as rings. The devices use electromagnetic fields to communicate with the metals.

In application, your best metal detector under $100 transmits an electromagnetic field into the ground. If there is a metal in the ground, it resends an electromagnetic field to the detector, and then you will hear an audible alert.

The metal detecting device has several parts that make your work easier. These include a control box, a search coil, a shaft, grip, and arm cuff. In addition, there are various metal detector models for different experience levels, from beginner to pro.

Regardless of your treasure-hunting skill level, we have compiled a list of the best metal detectors under $100 you can buy today. These cheap metal detectors will help you discover hidden treasures in the ground in no time. Read on to discover your most compatible metal detector.

Parts of a Metal Detector

When buying a metal detector, you will need to understand its parts.

  1. The control box is the part that hosts the detector’s electronics. It produces signals sent to the ground and processes signals received from the detected metals to produce an audible alert. In addition, it is also the metal detector part that has display circuitry, batteries, and control buttons.
  2. When detecting metals, the search coil is a part you point to the ground. The search coil transmits and receives electromagnetic signals when treasure hunting. It is connected to the control box through a wire to enable an audible alert when you find a metal.
  3. The shaft connects the control box and the search coil, including the connecting wire. When buying your best metal detectors, look for an adjustable shaft since it allows you to explore different landscapes.
  4. The grip is the part you hold when detecting metals. It is usually connected above the control box on one end of the shaft. When buying the best metal detector, look for an ergonomic grip to reduce arm fatigue on long excursions.
  5. The arm cuff is another part that improves your comfort when detecting metals. It is attached to the shaft, and it helps you secure a good fit when detecting metals in different environments.

Factors to Consider Before You Buy the Best Metal Detector Under $100

According to the United States Environmental Protection Agency, EPA, today’s metal detectors can be used in professional and hobbies to detect ferrous and non-ferrous metals. As a result, while you can find your buried treasures, you can also use the metal detectors to find contaminants in water and other places.

When buying a cheap metal detector, here are the factors you need to pay attention to;

a) Price

The best consideration to make when buying a metal detector is the price. After deciding to go for the best metal detector under $100, you need to look for the features to make your purchase worthwhile.

b) Operating frequency

When buying the best metal detectors under $100, you need to understand what an operating frequency is. Expressed in Kilohertsz or KHz per second, the operating frequency refers to how many electromagnetic waves the detector can produce in a second.

Metal detectors generally have operating frequencies between 5 kHz per second and 25 kHz per second. For better understanding, a metal detector with an operating frequency of 25kHz per second can produce 25000 electromagnetic fields per second. 

When choosing the operating frequency, it is imperative to understand what levels are useful for your excursions. In simpler terms, a high operating frequency does not always translate into better detection results. Rather, you will also need to understand the metals you target, their size, how deep into the ground they are buried, and how mineralized the soil is.

A metal detector with a low frequency generally targets more conductive metals buried deep into the ground. The low frequency translates into longer wavelengths that penetrate soil obstacles to tell where the metal is. This detector is suitable for copper, brass, nickel, silver, and more conducive metals.

On the other hand, a high frequency makes a sensitive metal detector with higher signal strength. Therefore, it will be best suited for detecting gold, iron, and other ferrous metals. If you can’t seem to find a quality metal detector for your needs, you can choose between a single-frequency and multi-frequency metal detector.

For the under $100 budget, you will likely find single-frequency metal detectors. These detectors only operate at one frequency, either below 10kHz or above 25kHz. The single-frequency below 10kHz will detect metals with high conductivity buried deep, while the latter will target low-conductivity metals near the ground surface.

If lucky, you can also find multi-frequency metal detectors that can simultaneously operate on two or more frequencies. While such a device will tend to be an expensive metal detector, you will also need a great deal of experience to understand all the alerts you get.

c) The metal detector sensitivity level

The sensitivity of your metal detectors under $100 determines how fast they can detect metals buried beneath the ground. Highly sensitive detectors, such as the Marnur metal detector, will detect even the smallest pieces of metal. Still, you will also need to consider other factors such as minerals in the soil and how deep they are buried.

d) Ground balance

As we mentioned above, some factors such as soil mineralization can affect how well you target wanted metals. When buying a metal detector, you can look for the ground balance feature, which aims to eliminate ground signals, so you get alerts for your target metal.

Without a ground balance feature, you might have your small targeted metal signals masked by signals received from soil minerals. Unfortunately, most soil minerals, such as iron particles in fine earth, will trigger your metals detector similarly to a metal.

A good metal detector can have either of three main ground balance types

  • Manual ground balance. You manually adjust the settings to hear more of your targeted metal than the ground minerals.
  • Automatic ground balance where the metal detector picks the best ground balance setting. This ground balance feature is better than the manual setting because of better accuracy.
  • Tracking ground balance. The feature is ideal when treasure-hunting in different landscapes, like from the park to a beach. Naturally, the ground minerals will be different, so the metal detector will automatically apply changes as you go.

e) Metal discrimination

When looking for a metal detector, understand if it has a discrimination feature. It is a feature that allows you to decide which metals you want to detect. For example, you can choose to detect gold, thus ignoring iron or nickel. Your metal detector will not send alerts for ignored or rejected metals when the feature is turned on.

f) Detection Depth

Your metal detector under $100 is only good if it can tell you where to find buried treasures. As such, understanding the detection depth becomes imperative for your buying process. Detection depth is how deep your metal detector can sniff target metals.

Normally, the detection depth relies on a good search coil size, but other factors also come into play. For example, the size of the metal you are detecting can affect how deep your detector can detect. In addition, larger metals are easier to detect compared to smaller metals.

In addition, the shape and orientation of the target metal can also influence detection depth. For instance, a coin that sits upright will be harder to detect than a coin that lies flat. Similarly, a thin shape will be harder to detect than a round shape.

You will also want to understand the target material since your device will detect high conductive metals buried very deep compared to low conductive metals.

g) Ease of use

Great metal detectors are easy to use. When buying, look for different design features such as adjustable stem, lightweight construction, ergonomic grip, and sturdy arm cuff.
