Real-Life Applications for Metal Detectors

Over the years, metal detectors have surged in popularity. Metal detectors are ideal for finding metal objects that could be dangerous or even valuable. This can range from scrap metal to buried coins. Metal detectors consist of an oscillator that creates an alternating current that passes through the coil. If the circuit is interrupted by anything that conducts, then it will sound an alert. Alexander Graham Bell was the inventor of the first metal detector. It was designed to find the bullet that hit US President James Garfield after an assassination attempt.

What Can You Use a Metal Detector For?

You can use a metal detector for a lot of different things. It can be a simple tool used for detecting metal nails in a yard, or it can be used to detect weapons and contraband in airports. They can even be used to detect metal contaminants within food processing plants. Another application would be using them to locate underground utilities, including pipes and cables. Metal detectors can also be used to find copper wire, weapons, ammunition, and tools. The great thing about metal detectors is that you can use them to find metal objects such as silver or gold. By using a system that sends out different frequencies, such as tones, it’s easy to pinpoint what it is you’re scanning. The speed will increase when the target is made out of one type of metal. Depending on the makeup, it’s possible to listen for distinctive tones that come from within the coin so you can see if something is worth picking up or if it should just be discarded. You can also pair your metal detector with Minelab metal detectors and accessories, including pinpointers and gold-specific detectors. This makes it easier than ever to get the result you want from your treasure hunting.

What You Can’t Use a Metal Detector For

Metal detectors can’t detect things that have low conductivity steel. As stainless steel tends to have low magnetic permeability, it doesn’t produce a signal that is easy to detect. This makes it a poor conductor overall. Gold, silver, and bronze are very conductive, making them easy to detect overall. Metal detectors cannot detect pearls, gemstones, or anything else similar because even though they may sometimes contain metal traces, they do not contain enough to trigger the detector.

If you want to find coins, you should research before taking out your metal detector. Older coins will probably not contain gold or silver but be made of nickel or bronze. This will produce a weaker signal. You must also consider how conductive the ground is when searching for metal. It helps to search for mineralization for jewelry, as objects can easily become stuck. You must also avoid searching close to saltwater, as this will impact how well your metal detector can get a solid reading, so be mindful of that.
