A basic guide to buying metal detectors

There are few people in the world who haven’t walked through the metal detectors, be it in the shopping malls, movie theatres, airport, banks or some places of historical interest. These are mainly used as a means of safety precaution and ensure that you are walking into a safe area where every person has passed through the same stringent detector. These invariably make every person feel protected.

Metal detectors can be practically used in colleges, office buildings or any other place to create that overwhelming feeling of safety. People who are in charge of these detectors can control who can enter a particular area and what that person can bring along.


Many scientists and engineers towards the end of the nineteenth century with their knowledge of electrical theory tried to fabricate a device that could detect metal. Those machines were primitive and they utilised a lot of battery and worked only to some extent. In 1874, a Parisian inventor names Gustave Trouve designed a hand made held machine that could locate and extract metal objects like bullets or bombs on a human body. The modern development of metal detectors steadily began from the 1920s, and today modern models are completely computerised and use integrated circuits that allow the user to fit the sensitivity, discrimination, track speed, notch filters, threshold volume, etc. and keep those parameters in memory for future reference. Modern detectors are much lighter, consume less battery, power, deeper seeking and can discriminate better compared with the ones available just ten years back.

The metal detectors are widely used in the following fields:

These detectors are used for archaeological purposes to detect treasures. Not only that, they are even used for hobby activities such as coin shooting, prospecting, which means searching for precious metals like silver, copper and even gold in their natural forms like flake or nuggets, beach combing, which is hunting for lost coins on any beach. It is most importantly used for security screening and in industrial metal detecting.


This detector is made of an oscillator that can produce an alternating current passing through a coil which creates an alternating magnetic field. This implies that when an electronically conductive metal comes in close proximity with the detector, it creates eddies of air causing a change in the magnetic field, enabling the operator to detect the sources of the metal. Handheld detectors are commonest ones and are used in a majority of the cases. Even landmines can be distinguished with the use of handheld detectors with pre-installed whites accessories.

In order to keep your detector device safe and sound, it must be kept in proper teknetics accessories such as a control box which is suitable for keeping the detectors or coil covers to protect the coil in operation. If the detector is employed with hi-tech xp accessories like deus lite coil, or xp deus headphones, then it can increase the functionality of the detectors by a few times.

The handheld detectors are far more affordable compared to the walk-through detectors and can identify the presence of metallic objects that can be potentially dangerous. However, the walk-through machines are much more convenient and efficient, and you can use both in order to maximise safety in the vulnerable areas. Read more at Treasureland Detectors
