Discover the Technology Behind Metal Detection

Where innovation meets the thrill of discovery

What is

Metal Detection?

Metal detection involves using a specialised device to locate hidden or buried metal objects beneath the surface. It’s like a modern-day treasure hunt, where the treasure can range from old coins and jewellery to historical artifacts or even gold nuggets. Metal detectors work by sending an electromagnetic signal into the ground and listening for the response from metal objects. Many enjoy metal detecting as a hobby because it combines outdoor exploration with the thrill of discovery. It’s a way to connect with history, nature and produces an excitement of finding something unexpected.

How Does a Metal Detector Work?

Electromagnetic Search Coils

Metal detectors use electromagnetic search coils to generate a magnetic field that penetrates the ground. When this field interacts with metal objects, it produces a response signal that the detector’s circuitry can recognise and use to pinpoint the object’s location.

Target Identification

Advanced detectors analyse the type of metal by measuring its conductivity and magnetic properties. This process assigns a Target ID, helping users tell the difference between valuable finds such as coins and less-desirable items like bottle caps.

Ground Balancing

Metal detectors adapt to different soil conditions through ground balancing, which reduces interference from natural minerals. This helps maintain accurate detection, even in challenging environments such as beaches or highly mineralised ground.

Key Technologies

Multi-IQ

Multi-IQ

Multi-IQ is a metal detecting technology that sends out multiple search frequencies at once. Frequencies are like signals that help a detector “see” what’s underground. Low frequencies are better at finding bigger, deeper objects. High frequencies are better at picking up small or thin targets close to the surface. By using a full range of frequencies together, Multi-IQ gives you the best of both worlds, at the same time. This makes it more accurate in finding a wider variety of targets, and more reliable in tough conditions like mineralised ground or wet sand. It also helps tell the difference between something valuable and something you can ignore. That’s why it’s great for all types of detecting, from parks to beaches to remote treasure spots.
