This is a question we are asked often, Do Long Range Metal Detectors Work? So we thought that an article that answers this question should be useful to many detectorists who may have considered purchasing such a device but are unsure of some hype surrounding these devices. Anyway, I hope you enjoy reading this, and please do not hesitate to message us if you have any questions.
What is a long-range metal detector?
A long range metal detector is a type of metal detector that is designed to detect metal objects at greater distances than traditional metal detectors. These detectors use advanced technology to detect metal objects from up to several hundred feet away. Long range metal detectors are often used for treasure hunting, security, and military applications.
Who uses them?
Long-range metal detectors are often marketed as being able to detect metals at great depths or distances using various techniques, such as frequency scanning or resonance imaging. However, there is limited scientific evidence to support the effectiveness of these devices for detecting metals in the ground.
Many experts in the metal detecting community are sceptical of long-range detectors, and some even consider them to be fraudulent or scams. In general, traditional metal detectors that rely on electromagnetic induction and target discrimination are more widely used and trusted for metal detecting purposes. So, while there may be many instances where a long-range detector has been successful in detecting metal, however, they are not known for general metal detecting applications.
Long-range metal detectors typically rely on technologies that detect the presence of metal targets from a distance, such as a few hundred meters away, through various means like resonance imaging, and frequency scanning. However, the scientific technology for these devices is a patented confidential design that only a few manufacturers have the capability to manufacture products that function correctly.
Traditional V Long-Distance
Most traditional metal detectors used for treasure hunting and other applications rely on electromagnetic induction to detect metal targets within a few inches of the search coil. These detectors operate on the principle that when an electromagnetic field is applied to a metal object, it induces a current in the metal that can be detected by the search coil and relayed back to the control box to generate a signal. The Long-Range technology works by transmitting a series of electromagnetic signals at different frequencies and then analysing the reflected signals to detect metal objects.
Prospectors for Gold
While some manufacturers of long-range metal detectors claim that their devices can detect metal objects at great distances and depths, there is typically little empirical evidence to support these claims, however, many prospectors use these devices to find natural gold and buried treasures with regular success and some at impressive depths. The good quality Long Range detectors use resonance imaging to detect metal objects. This technology is based on the fact that every metal object emits its own unique frequency signature that can be detected by a sensor. The device emits a high frequency signal which ‘hits’ the metal target and the locator detects the signal which bounces back, from the frequency received it identifies the target type.
There is now clear evidence that the technology works well for certain applications, and conditions. Many detectorists use Long Range equipment successfully to find targets that are far too deep for conventional detectors. The recent advances in technology and design have seen a real improvement in performance. Below I have listed some Long Range detectors that we have tested and verified as good quality devices –
