Thanks to physicists, the theory of electromagnetism has been discovered and its principles are now being put to good use in the form of metal detectors.

At the basic level, metal detectors are pretty simple. What it has is a coil that produces alternating current that in turn produces a magnetic field that will interact with hidden metal which is how metal is detected.

Among the world’s top notch metal detectors, an electronics company down under has made its mark in the industry. Minelab Electronics Pty Ltd is an Australian company that specializes in electronic devices and which include an array of detection equipment for consumer and industrial usage. Their products have been used extensively by both the military and industry mining projects across the globe.

Minelab is dedicated in providing the best technologies for its clients. They have incredible people working behind the scenes to ensure that they can create and deliver products with exceptional quality.

They always keep their customers in mind and will always try to provide all the needs of their customers and business partners. The company is guided with philosophies like integrity and respect for people, good communication between them and their clients, and a constructive working environment. It is no wonder, therefore that the company is able to offer various innovative solutions.

Compared to some of the companies in the industry, Minelab is still very young. The company began in 1985 but since then, the company has aspired to be a leader in the field of metal detection.

Thanks to the highly competent research, engineering and development teams, the company was able to immediately break into a market that was dominated by industry giants that have more than 20 years of experience tucked under their belts. It was no easy feat, but the Minelab persevered until it reached the status that the company enjoys now.

Minelab today is known manufacturer and distributor of metal detection equipment and technologies in Australia, Europe and the United States. It also has earned the ISO 9001 Quality Endorsed Company level which ensures that their products are of highest quality.

The company is divided into divisions. This is to make sure that every target consumer will receive the company’s utmost attention. Minelab Countermine, for example, is a division wholly dedicated in creating the best technology in land mine detection. Their products have been used by humanitarian and military organizations extensively in service of de-mining communities affected by conflicts.

The Minelab Consumer, on the other hand, provides the world market with high quality gold, jewellery, coin and treasure detecting products. Their metal detectors have been designed to get optimum results regardless of ground terrain or conditions.

Another division of the company is the Minelab Security division which focuses on making superior detectors and scanners for security purposes.

The MF-1 Hand Held Security Scanner, for instance, is fast becoming the “in” thing in portable security detection and is beginning to be popular in domestic and international airports, for law enforcement and for security screening purposes.

Metal detectors are interesting pieces of technology. They have a variety of uses and have become even more versatile throughout the years. Ever since the first metal detectors came out in the 19th century, scientists and engineers never stopped working on better and more efficient designs.

Nowadays, there are metal detectors that can pinpoint metals so accurately that they have become indispensable tools in fields like mineralogy, engineering, security and even in the military.

From the crude models of the 19th century, the modern detectors had its debut in the 1930s when Gerhard Fischer released and patented his very own metal detector. Fischer’s design used resonating coils to detect the presence of metal under the ground. These metal detectors proved to be an asset during World War II.

Metal detectors were used during the war to find land mines scattered across the paths of troops. They saved a number of soldiers back then. However, these metal detectors could have been more useful if they were not that heavy. Early designs of metal detectors were not that convenient as compared today. These detectors require a great amount of “juice” to power up which means lugging behind heavy batteries.

The modern detectors basically are made up of coils and uses electromagnetic induction to detect the presence of metal. Aside from the portable metal detectors that we have grown accustomed to and use in hobbies and games like treasure hunting, there are some bigger models that are used mainly in security and related fields.

Other uses for metal detectors include detection of foreign objects in food. These pieces of equipment are of course very useful in the construction industry as well. You could easily detect steel reinforcing bars, pipes and wires that are buried in walls and floors with a detector.

Powerful metal detectors are also used to determine the location of mineral ores for the mining industry. In the field of archaeology, artifacts can be detected even if they are buried deep underneath sand or soil. During rescue missions, sometimes metal detectors also come in handy. In places like airports, security uses walk in metal detectors to determine if people are carrying metallic objects like knives and guns which can cause potential dangers to passengers or commuters.

The standard coil detectors were the trend back then, but recent technologies have brought about new breeds of metal detectors. You can now see the Beat Balance and Coil Coupled Operation metal detectors which were made available to the public just a couple of years ago.

Most machines are operated using microchips. This can be seen when opening the hood of the car and looking at the control box, the remote control of the television and the interior of the microwave oven. These little things can be programmed to do whatever the person wants in a matter of seconds, which is something everyone needs living the digital age.

Metal detectors also operate using the same concept. Though this machine has been around for quite some time, advances through the years has made it much better than it was before allowing the person to use it to even detect the smallest metallic object in any terrain.

The kind of chip commonly used by the metal detector is known as the 7400 series logic. These are the tiny pins located in each card that becomes the controls of the machine. Manufactures have to be test this out so that only those who pass quality control will end up in the display shelves and into the hands of the customer.

The control box is powered by one or two 9 volt alkaline batteries. When it is activated, the person can already adjust the settings and start searching for objects buried underneath. Before using the metal detector, it is always best to study the model and be familiar with how to use it. The individual should let it warm up for 30 minutes and then practice using it.

Lately, there have been some improvements with these devices. A better chip known as the 18 pin IC allows the individual to home in on an object up to more than a few inches away from it.

While its true that treasure hunters don’t pay that much attention to this and are only concerned with how well the detector performs, this is something worth knowing should any problem happen. The person will be able to understand what the technician is talking about to know which part will be replaced.

Those who are familiar with electronics can even make one in the garage by getting some of those chips from a radio shack or the junk yard and use it to assemble a metal detector to be able to search for the same thing.

The metal detectors of the past are nothing compared to what is available now in the market. What used to be bulky is now lightweight and handheld enabling even a child to play with it.

A compass is an instrument used for navigation. It helps one find one’s bearing in relation to the four cardinal directions based on the ability of the compass’ needle point to align itself to the earth’s north. The compass uses magnetism and the principles of electromagnetism to be able to tell the correct direction. Given this information about a compass, it would seem that the word compass is a good brand name for a metal detector.

Compass Electronics produces metal detectors for treasure hunting and metal detecting in general. For seasoned metal hunters, the Compass metal detector is the detecting tool of choice. Just like a compass can readily help one find the correct path, a Compass metal detector helps one find hard to find metals hidden beyond sight.

Compass Electronics had its say in revolutionizing the technology for metal detectors. It introduced Compass metal detectors with two D shaped coils mounted together to form a circle and this design has been widely adopted by other metal detectors.

All metal detector dealers and outlets will have a wide array of Compass metal detectors to choose from. There are different designs of Compass metal detectors for specialized detecting needs. You can pick one that will suit your style, preferences and budget. If you are unsure about what type of Compass metal detector to purchase, or it is your first time to try the Compass brand, you may ask the advice and help of qualified individuals from good and reliable metal detector stores.

You can also opt to ask around from other Compass metal detector users about what they think about their gadgets and how effective it is in helping them in their metal detection. It is always helpful to get a peer’s review because that way, you know you will get unbiased opinions and they will want to help you. For lack of personal peer that may be into metal detecting like you, you can check online for reviews, particularly on user ratings of the Compass metal detector.

If it is your first foray into the world of metal detection, you may become daunted by the amount of choices one has when it comes to purchasing a metal detector. Keep in mind however that no matter how good a metal detector brand happens to be, its effectivity is dependent on your skills as a metal detector as well as its features compatibility with the type of metal detection you want to achieve.

The world is becoming a dangerous place to live. People who want to cause danger and those who want to alarm an otherwise peaceful community are becoming more and more ingenious so even a harmless office supply like a paper clip can be one of the components of a destructive device.

This is such a bad news not only for the general public but also for the officials whose task is to make sure the peace and order reign in the area of responsibilities. The growing menace of the society poses a big problem that is not at all becoming easy to solve. With this in mind, there has to be creative and smarter solutions in approaching the situations.

One of the things that can be done is to thoroughly implement standard security measures. These measures are usually sufficient if only security guards or anyone tasked to go about these measures would only be patient enough to go through each step.

Sometimes because nothing bad is happening, everyone becomes lax including the people who should be always keen on watching suspicious things and behaviors. Only when the news reports of failed bombings or successful terrorist operations do everyone go back to being always on their toes. It is about time that people take seriously the call to be vigilant.

Second is to have hand held metal detectors in all establishments. Metals are usually the main driving force behind devices so detecting a metal device early on can save everyone of a brewing future trouble. Personnel at the doors should not be scared to use the hand held metal detector to anyone who enters even if there are VIP’s.

It can be a hassle but it is okay to have a bit hassle than to have none and ending up blaming the fact that the person who was able to infiltrate a said building or establishment just got in without any trouble. Though there are many possible hiding places of metal pieces, a person who knows how to use a hand held metal director would have an idea where to more or less look for metal stuff.

These two things can certainly have an impact in security and to think these are but basic measures that can be applied by anyone or anywhere. Make sure then to do the two things above to make yourself secure during perilous times like what we are experiencing now.
