If you are engaged in security jobs or looking for precious metals, then this article is for you. The handheld metal detector is an excellent tool that can help you locate metal objects wherever they may be hiding. These devices have a wide range of applications, from metal detection in security to finding lost objects in your backyard. In this article, we will provide you with a comprehensive guide to handheld metal detectors.
1. How Handheld Metal Detectors Work
A Hand Held metal detector sends an electromagnetic field into the ground or any other material, and if there is any metal in the vicinity, it will be affected by the electromagnetic field. Metal detectors can detect a variety of metals, from iron to precious metals like gold and silver. Once the detector detects a metal object, it will notify you with an audible or visual signal.
2. Types of Handheld Metal Detectors
There are various types of handheld metal detectors available in the market, and each one has its unique features and functions. Some of the most popular types of handheld metal detectors include:
– Pulse Induction (PI) Metal Detector: This type of detector is ideal for detecting metal objects buried deep in the ground. It can penetrate through soil and other debris to pinpoint the location of the object.
– Very Low-Frequency (VLF) Metal Detector: This type of detector is more sensitive than the PI metal detector and can detect both ferrous and non-ferrous metals. It is commonly used for gold prospecting and relic hunting.
– Beat-Frequency Oscillation (BFO) Metal Detector: This is the most basic type of metal detector and is suitable for beginners. It works by creating an oscillating magnetic field that is affected by metal objects.
3. Factors to Consider When Buying a Handheld Metal Detector
Various factors need to be considered when purchasing a handheld metal detector, including sensitivity, discrimination, frequency, and coil size. Sensitivity refers to the ability of the detector to detect metal objects, while discrimination refers to its ability to distinguish between valuable metals and trash. Frequency determines the depth of penetration, and coil size is also a factor that can impact the device’s sensitivity.
4. Applications of Handheld Metal Detectors
Handheld metal detectors have a wide range of applications, from security and law enforcement to treasure hunting and prospecting. Some of the most common applications include:
– Security: Metal detectors are commonly used in airports, schools, and other public places to detect weapons and other dangerous items.
– Archaeology: Metal detectors are used to locate historical artifacts, including coins, jewelry, and weapons.
– Prospecting: Metal detectors can be used to search for precious metals, including gold, silver, and platinum.
– Recreation: Metal detecting can be a fun hobby for people of all ages, as long as it is done responsibly.
In conclusion, the handheld metal detector is a useful tool that can be used in various applications, from security to treasure hunting. Choosing the right metal detector depends on your specific needs, and you should consider factors like sensitivity, discrimination, and frequency when making your purchase. Whether you’re a professional security officer or a hobbyist looking for treasure, a handheld metal detector can help you find what you’re looking for.
