What are metal detectors?
Metal detectors are devices that are used to detect the presence of metals nearby. They do this through the projection of certain electromagnetic waves using a sensor probe, which is disrupted by the field around metal and then sent back to the detector. The detector then gives off a signal – either through the blinking of an LED, or the increase in tonal frequency and pitch in headphones. Some detectors also measure the depth of metal and indicate these on digital screens attached to the metal detectors.
The utility of metal detectors
Metal detectors are such a huge part of the operational procedures of almost every organization and field of stature in the present world. Think airports, banks and government offices; even on a grand scale, metal detectors are still being used to detect metal in the most crucial ways. As we know it, the security apparatus of most countries would crumble should metal detectors cease to exist today.
Let’s take it down a notch though; let’s consider simple metal detectors like pulse induction detectors, VLF detectors, and Multi-Frequency detectors. Although they may not seem as consequential as metal detectors used for security reasons in mainstream fields, they are just as important and even more useful in most cases. Below is a small list of things metal detectors are also typically used for;

Treasure hunting
Believe it or not, treasure hunting is a very popular, very lucrative field. While it may not be as stable or as promising as your regular nine-to-five job, whipping out the gold detector and trying your luck in odd places is one way to carve your way to financial independence.
If you are sceptical about how profitable treasure hunting can get, do a bit of research on the Boot of Cortez, the Ringlemere Cup, the Crosby Garrett Helmet, and the Hand of Faith. Each of these are treasures that were found by unsuspecting folks doing simple metal detecting, and each was sold for over six figures (some of them were sold for over a million dollars even).
The most fascinating thing about this field is that anyone can be a winner. A boy in New Mexico unearthed – with a simple metal detector built by his grandfather – a meteor piece that had been on earth for about 10,000 years. You do not have to empty your wallets on an overpriced metal detector to strike gold (literally!). Treasure hunting is a field for everyone and anyone. It may not be to your taste, but it is definitely an option worth exploring with a metal detector.

Archaeology
To the dilettante, this is basically just a subset (or a composite of, if we’re being pedantic) treasure hunting. After all, a lot of research facilities, governments, and collectors would love to get their hands on every and any bit of history they could hope to find. To the expert though, this line of thought is heretic at best, a dismissal of the years of study and research that goes into the art of identifying, excavating and preserving historical artefacts for posterity’s sake.
Regardless of whichever group you belong to, metal detectors would make the job easier. Ever since the 1950s, this device has been considered a standard requirement for the excavation of archaeological sites. As a survey tool, its presence on the field means that archaeologists would find it easy to unearth jewellery, ancient domestic utensils, jars, etc. You aren’t likely to find an expert in the field who doesn’t have experience using the best metal detectors.

In the military
Being in the military means consistently putting yourself in danger – one of the many occupational hazards of being a soldier is not being sure of where to even walk due to the installation of mines on territorial premises. Military dogs actually detect these things, but the casualty rate isn’t too encouraging even at that. The best way to avoid these dangers is to use a metal detector. It would help to detect the metal casing of the mines before you even get to them.
Metal detectors are also used by the military for security reasons (like in airports and banks), but those are, of course, different from the hobbyist metal detector hires online.

As a hobby
The art of metal detection does not need to be limited to a career or a goal. Sometimes it can be an outlet for people to revel in – a time when the headphones are on and the comforting but consistent beep of the metal detector is only interrupted by proximity to a potential score.
You can also decide to tie it in with another hobby like scrap collecting or metal identification. The possibilities are endless and the sky’s the limit. You exercise your body by walking around and relaxing your mind by letting yourself focus on one thing only. You would find at the end of the day that the benefits you are getting by choosing to do prospects are immense. What’s more, there are metal detectors for sale online that fit your every need.

Underwater excavation
Yes, there are metal detectors that work underwater. Although they are mostly used by construction companies to locate pipelines and undersea cables, scuba divers with an interest in undersea metals and marine biologists also use them too.
These underwater metal detectors are, of course, waterproof. Most are also able to adjust the search depth of the electromagnetic waves that are emitted by the sensor. These devices aren’t as expensive as you might think too – you could easily cop one for around $700 to $800. 
Metal detectors are also used in mining and construction, for obvious reasons. These devices are very versatile in their utility.
