Metal detectors are primarily used for detecting hidden objects underground such as buried treasure, weapons or even entire bunkers. Metal detection is also used in walk-through or handheld security checks, and investigators and private detectives sometimes use metal detectors to gather evidence.
We’ve all seen metal detectors in low-budget cartoons and spin-offs, but only a few people have actually seen one in real life. And dare we say it, the real thing is not as simple as the cartoons make out. For one thing, there are at least three different types of detector, each using its own complicated method to keep track of metallic objects beneath the earth. Here, we have narrowed the choice down to the three basic types along with a handy guide to help you buy them.
Very Low Frequency Metal Detectors
A very low frequency (VLF) detector is the most popular and familiar kind of metal detector. This is in part due to its cheapness and relatively high performance. It basically works by employing two wire coils called the transmitter and receiver. The transmitter generates a low-frequency, low-range magnetic field, while the receiver detects any magnetic signals emitting from or being reflecting off the item underground. If there really is metal beneath your feet, the detector will make a sound to inform you. It all sounds very fancy and smart, but is in fact not too complicated.
We recommend this type for those who want to metal detect on a relatively tight budget. Naturally, the range of the VLF detector is very low so it may not detect objects deeper underground. But rest assured, this type is perfect for scavenger hunting. Most security detectors are also VLF detectors, albeit a bit stronger.

Pulse Induction Metal Detectors
Pulse induction detectors, also known as PI, use a single metal coil which sends a signal deep into the ground. This type of detector is mainly used for deep hunting for gold, platinum or other precious metals. Typically, gold and the like are found deep underground, so a metal detector which has a broader range is perfect for this job. It has other uses as well. If you want to detect a large but deeply buried object like an underground bunker, a basement or a weapon, then PI is perfect for you.
One other thing which intrigues us about pulse induction metal detectors is that they can differentiate between accidental signal detection and the signals actually emitted by the metal object. You see, when you receive signals from below the ground, they’re likely those of the desired object, but occasionally other surrounding signals can get mixed up. A good PI detector can differentiate between the two. However, this feature makes them more expensive and harder to find than the VLF versions.

Industrial Metal Detectors
An industrial metal detector is used in walk-through security lines and checks. Although they employ VLF and beat frequency oscillation (BFO), they are entirely different and much more sensitive, noticing even the tiniest change in frequency. This makes them great for detecting security hazards such as bombs, firearms, or knives. One important thing to note is that these types are costly and should only be bought if you’re running a business and want more security for your offices, buildings, hotels, malls, parks or cinemas. However, employing metal detectors for security is a great idea, so don’t be afraid to go through with it.
XSMeterHouse Security Metal Detector
The XSMeterHouse Security Metal Detector is easy to use and detects metal very precisely. It’s light as a feather and made mostly for manual operations. With this in mind, it can be used wherever protection and metal detection is required, from airports and government buildings to schools, conference centres, clubs and sports events. In addition to being used for security purposes, this metal detector can also be used by home or landowners for detecting metal that is hidden underground, saving you from having to buy new tyres or from stepping on sharp objects!
Features of XSMeterHouse Security Metal Detector
Let’s take a closer look at this handy metal detector and see why it is so popular. It can detect large and small objects with the help of 16 ice indicators that detect the strength of the signal, depending on the distance of the metal object. Therefore, the indicator lights gradually change from green to red based on signal strength, meaning that you will not miss any metal object. However, the sensitivity can be manually adjusted for specific situations that require higher or lower responsiveness. Another key point is that you can choose one out of two alternative alert options – audio or vibration – whatever fits the occasion better.

Purpose• Before finalising a purchase, it is crucial to understand what you want to get out of a metal detector. Do you want to go treasure hunting as a hobby? Do you want to hunt for precious objects and gold? Are you a professional CEO looking to enhance your security systems? There are several types of metal detectors on the market which can be used for various purposes. So first decide why you need one before thinking about what type to buy.
TypeWe have talked about the three main types of technology used in metal detectors: VLF, PI and BFO. For hobbyists, we recommend either VLF or BFO (with BFO being more budget friendly). For those who are serious about finding precious items hidden in their backyards, or who want to discover gold, we recommend the PI variety, as it has more of a range than the others. Another type, the industrial kind, is used in security systems and mainly uses VLF technology. For security purposes, a special type of VLF detector specifically made for security checks should be enough. Walk-through detectors are great if you don’t have time to stop each and every person and check them, and handheld detectors work best if you have time to search everyone individually and by hand.
SizeSize may seem like the least of your concerns, but it can have a lasting impact on how you use the device. A metal detector which is too high or too low can, over time, cause back pain and neck issues, and may even lead to some chronic disorders. Buy a detector which is about half your height. If the detector is to be used by multiple people, then keep each of their heights in mind, calculate the average and buy a detector suited for all. In this case, it would be best to buy one with an adjustable length.
RangeThe range of the detector mostly depends on its type, but that doesn’t mean there aren’t range variations among the same types. Some detectors are very efficient and can have a very high range even while employing simple VLF or BFO. Others may have a very low range due to inadequate production and cheap quality. It is essential always to test out the range. A great way of doing this would be to bury an object a few feet underground and see if your detector can find it.
Durability and LifespanMetal detectors do have a lifespan, and if yours has a very short one, then you’re on to a loser. Metal detectors can lose their efficiency, range and strength over time. The signals may weaken, and the coils may break or compress. The handle and frame can get rusty and over time break or get dented. In cases like these, it is essential to always check for strength. The handle and bodywork should be rust proof and either made from steel or brass. The coils and transmitters should be made of a very conductive and strong material, usually copper or tungsten.
PriceLast but not least, it is important to factor the price of the detector into your purchase. Most BFO detectors are the cheapest, followed by VLF, with PI and specialised gold detectors being the most expensive. The way we see it, you shouldn’t buy a PI detector unless you absolutely need it. If you do need it and you can afford it, then go for it. Whatever your budget, be sure to prioritise your health and personal requirements when selecting a model.
