There are so many different options to choose from, which can make finding the best metal detector for your needs a bit challenging. In an effort to help you find the best metal detector for your needs, we have put together this handy buyer’s guide. This guide highlights the types of metal detectors, the factors to consider when choosing a metal detector, the features that metal detectors can offer, and the best metal detector brands. With the information presented in this guide, you will be well on your way to finding a great metal detector for your needs.
The Types of Metal Detectors
In order to find the best metal detector for your needs, the first thing you need to do is understand the different types that are available. Metal detectors differ in the way that they operate to find metal. There are four main types of metal detectors, which include:
- The beat frequency oscillation metal detector
- The low frequency metal detector
- The pulse induction metal detector
- The industrial metal detector
Below, you will find a detailed description of each of these types of metal detectors.
The Beat Frequency Oscillation Metal Detector
This is the most basic of all metal detectors. The concept behind how it works is very simple and straightforward. It has one large coil that is attached to the base of the detector, and another smaller coil that is attached slightly higher. Both of the coils are connected to oscillators, which generate a frequency; however, both of these coils operate at a different frequency. There are speakers attached to the metal detector, and it is the difference in frequencies that the speakers attached to the metal detector detect. There can be one or more speakers, and they are usually a wearable headpiece. They produce an audible steady hum that can be heard by the person using the detector. When the base coil comes across a metallic object, the interaction of electromagnetic causes an interference in the frequency transmission. This interference is what is used as proof of the existence of a metal object.
The beat frequency metal detector is the weakest of all metal detectors. It has the ability to find objects located about two feet below ground, but not much deeper.
The Low Frequency Metal Detector
The low frequency metal detector is one of the most popular metal detectors, especially among those who are experienced treasure seekers. This type of detector can be highly accurate and sensitive. It features a pair of coils, which work together. The first coil is the transmitter, and it usually gives off an intense electric current. The second coil is a receiver, and it picks up the signal from the main coil and amplifies it. The transmitter coil works by looping a magnetic field above and below ground. This field usually extends about two feet into the ground. The field usually stays that way until it comes across a metal object. When this happens, the object develops a magnetic current. This current then interferes with the magnetic loop running into the ground. The secondary coil the picks up the interference and magnifies the interference, sending it to an audio system that is attached to the metal detector, which allows the user to detect when an object has been located in the ground. Each metal objector generates a different frequency. Highly magnetic objects, such as steel and iron, generate a very power field. This field is quite distinct and some detectors have the technology to detect it. As a result, you will not waste time digging up worthless objects. In addition, it can detect objects with a very low magnetic pulse, including precious objects, such as gold. With the low frequency metal detector, you will have a greater chance of discovering precious items underground.
The Pulse Induction Metal Detector
The Pulse Induction metal detector is latest innovation in metal detectors. They are often used to detecting concealed weapons at security checkpoints; however, it should be noted that this technology is not very efficient in differentiating the different types of metals. The Pulse Induction metal detector relies on the theory of echolocation. This type of metal detector usually relies on one coil or a number of coils that work together as one, unlike other detectors that rely on two complementary coils that work together. Furthermore, the detector works by sending a short burst of powerful current through the coils. The pulse disappears and the magnetic field quickly reverses, which then generates a short electric current. The current that is generated is used to create a report on the objects that are found in the ground. If there is a magnetic object buried in the ground, it will interfere with the current generated. This model works well because the pulsing motion lets it detect only signals it has generated. On the downside, the pulse induction metal detector is the most expensive of all metal detectors.
The Industrial Metal Detector
The industrial metal detector is most commonly used for security purpose. They are not detectors that are used for finding treasures. The most common industrial detector is the doorframe detector, which is often used in airports and in other secure buildings. This type of detector works on the basic principles of electromagnetism to work. This type of detector is very effective in deterring criminals from accessing a building with concealed weapons.
Factors to Consider When Choosing a Metal Detector
In order to choose the best metal detector for your specific needs, there are a number of factors that you are going to want to take into consideration. By considering these factors, you will be able to choose the best metal detector for your particular needs. Some of the most important factors to consider include where you will be using the metal detector, how often you will be using it, and the cost of the metal detector, among other things. To learn more about these and other factors that we consider to be the most important when shopping for a metal detector, please keep on reading.
Where will you be using the metal detector?
Will you be using your metal detector on the beach, in the woods, or on a grassy field? Where you will be using it is an important factor to consider because different metal detectors work better with different surfaces. You want to make sure that you choose a metal detector that will work on the surface that you plan on using it on.
What are you hoping to find?
Another important factor to consider is your intended purpose of using the metal detector. Will you be using it to find trinkets and other random items, or will you be using it for serious treasure hunting? Some metal detectors are better at picking up certain materials than others. If you are going to be looking for gold, for example, you want to make sure that you choose a metal detector that can easily pick up the frequencies that gold emits.
The weight of the metal detector
You are also going to want to consider the weight of the metal detector. Because you will be holding it and passing it over surfaces, you want to make sure that it is as comfortable as possible to hold for extended periods of time. A lighter weight metal detector is definitely much easier to use than one that is heavy and bulky. Also, the lighter weight of the metal detector, the more stability you will have while using it, which will allow you greater success.
The accuracy of the metal detector
Another important factor to consider is the accuracy of the metal detector. You want to make sure that your metal detector can accurately pick up frequencies, otherwise you won’t be able to find treasures as efficiently as you may hope.
How often will you be using the metal detector?
Are you planning on using your metal detector once in a while, or will you be using more frequently? If you plan on using it a lot, you want to make sure that you choose a detector that has a durable design and that is constructed of high quality materials. Obviously, the more you use it, the more wear and tear it will endure, which is why you want to make sure that you choose a thoughtfully constructed metal detector if you plan on using it often.
How much do you plan on spending on the metal detector?
You also want to take your budget into consideration when you are shopping for a metal detector. These devices can vary significantly in price, with more advanced models that offer more features costing more. It is important to set a budget before you start shopping so that you can make sure that you don’t spend more than you are comfortable with.
The battery power
You should also consider the power of the battery when choosing a metal detector. You want to make sure that it will be charged up when you want to use it, and that it won’t lose its charge while you are using it. The longer the battery remains charged, the longer you will be able to use your metal detector between charges.
Features Metal Detectors Can Offer
There are a number of features that metal detectors can offer. These features are intended to make the metal detector easier to use, and more functional. As mentioned above, the more features that the metal detector offers, the more expensive it will be. It is important to understand the different features that metal detectors can offer so that you can determine whether you want or need them, or if they are worth the extra investment.
Here is a look at some of the top features that metal detectors can offer.
With a target identification feature, you will be able to identify the object that the metal detector has detected. This will allow you to determine whether or not you want to dig up the item or not. The target identification feature classified items found into categories: copper, iron, nickel, coins, etc. Some metal detectors have more advanced target identification that will allow you to program the items you are searching for.
Some metal detectors emit different tones when they identify different objects; for example, it may emit a low tone when it finds copper, and a high tone when it finds gold.
