Pulse Induction (PI) metal detector is a machine used to locate and detect several types and grades of metals using the science of electromagnetic. Pulse Induction metal detectors are different and more advanced than any other type of metal detector. It has a single coil device that works both as a transmitter and receiver and is a lot easier to use in searching even on higher grounds and even on salty water. It has the best technology nowadays to use in finding gold, high-grade metals, and other precious minerals.
A pulse Induction metal detector is an instrument used to detect and locate precious metals. Typically, metal detectors have long been used to detect hidden treasures, historical artifacts, and other underground activities. But Pulse Induction metal detector has a more advanced technology that is more useful to detect precious minerals like gold, copper, aluminium, and other non-rusted metals. The best thing about its technology is that it is not affected by any typical metal, and you can use it anywhere, like in the sand, fresh or salty water, and heavy rocks.
How do PI Metal Detectors Work?
These detectors have a more advanced method with only 1 coil working as a receiver and transmitter, where voltage pulses are sent into the target medium, which generates an electromagnetic field. According to the mining industries, one more advantage of the PI metal detectors is that it works very well both underground and underwater. Also, it has waterproof abilities and can sustain up to 10 feet (3.05 m). There are also metal detectors that can operate underwater even at more depth. Underwater treasure hunting is an excellent activity that can also make you rich. Read this article about underwater metal detectors with the list of best detectors for scuba diving treasure hunting.
History of Metal Detector
When did metal detectors start? Metal detectors have long been used since the 16th century. It was widely used by archaeologists and used to find historical objects and artifacts. It was also used to search for treasures that were said to be hidden or left by some explorers. Later on, it was discovered that it could be helpful to locate vintage bombs planted from World War. It was also used to locate land mines and weapons.
Also, since the beginning, it was believed that humans discovered minerals, even without advanced technology yet. But they start to know the value and benefits of those minerals, so they start to work hard and search about it anyway. Due to scientific development, humans started to invent devices and develop it to search for valuable minerals.
According to the experts, the first industrial metal detector was developed in the 1960s and was used in mineral prospecting and treasure hunting. Over the years, it began to be used industrially like the mining industries to locate and search for precious metals. Also, it became used by construction engineering to detect metals, steels, bars, pipes, and wires under concrete buildings.
Metal detectors have gone through generations over the years. The metal detector industries never stopped developing, innovating, and working on new advanced technology to find an easier way to find these valuable minerals.
Advantages of Pulse Induction Metal Detectors
According to the experts, it was challenging for them to locate their prospects due to the mineralization because the normal metal detectors are very susceptible to extremely mineralized ground. So then, Pulse Induction technology was created.
Pulse Induction metal detectors have more capability to locate the metals even if it is very deeply hidden. It has the main feature wherein the detector coils are bigger and more powerful to initiate signal compared to the VLF (Very Low Frequency) detectors.
Pulse Induction metal detectors are the only ones who have the functional capabilities to work in saltwater. It was impossible for the VFL to be used on the oceans because of the minerals and salt occurrence.
For gold miners, the Pulse Induction metal detector is the best technology to be used. The VLF has a slim chance of finding gold, and the signal result can be very difficult to determine. So, with the Pulse Induction metal detector’s ability, it has a very powerful search system where they get to recognize even the smallest gold nuggets in the area.
Disadvantages of Pulse Induction Metal Detectors
Generally, Pulse Induction metal detectors are more expensive compared to the VLF detectors. It is very common for new technology tools available in the market to have more expensive prices. The price normally ranges from $2,000 to $5,000. So, if you find it too expensive and just need an ordinary metal detector, it might be better to get the Very Low Frequency metal detector.
However, due to the non-discrimination features of the Pulse Induction metal detector, it means that it’s not able to recognize whatever thing is present or not. So, you need to be always prepared to dig if it gives you any signal. The problem is, if the particular area of your search has a pile of junk, the Pulse Induction metal detector won’t help you with this.
Another thing is, the PI metal detectors, with their coil technology, are very prone to the geomagnetic field. So, chances are it will give you a signal that you found something, but it’s actually nothing. So, this might happen many times.
We believe that there are still a lot of lost artifacts, treasures, and undiscovered valuables out there, specifically underwater. So, for archaeologists, treasure hunters, and miners, there is no better technology that can help you than the Pulse Induction metal detectors. It can work in the deepest search, fresh and salty water, and rocky areas. You will find the value of it once you find your precious discoveries.
