Searching for jewelry and other gold items is a profitable activity, but obtaining results requires the use of special equipment. Such devices include various metal detectors that allow you to find precious metals.
The operation of such devices is based on the property of materials to reflect sound and radio waves. A gold detector analyzes the received signals and draws conclusions about the chemical composition of the find and its value. A metal detector can be used for gold not only on your own property but also in other public places.
Searching for gold coins can be seen not only as a way to earn extra money but also as a nice pastime. Adventure enthusiasts can fully enjoy the process and have a good time. As for real treasure hunters, they can expect productive work.
The principle of operation of a metal detector
Treasure hunters use a metal detector for gold to study the composition of the underlying surface. The device allows for the detection of metal elements in the soil, water, and sand. The size of the find and its chemical composition do not matter, as the equipment operates on the principle of detecting foreign elements.
Radio waves emitted by the device are used to search for gold. The reflected signal is recorded by the device and allows for the reconstruction of the picture hidden beneath the surface of the water or soil. The nature of the wave that returns during the search enables the determination of the presence of metal.
The operation of metal detectors is quite similar to that of a sonar – a device used for fishing. Waves reflect off sand, water, plants, and fish in exactly the same way. The use of special equipment simplifies the search process.
There are several types of metal detectors that vary in design features:
The VLF and PI schemes (Very Low Frequency and Pulse Induction, respectively). The device operates using transmitting and receiving antennas. They are combined into one unit. While working with the device, it is necessary to move in different directions, as the radio waves do not reflect back from the surface where they were directed.
RF (Radio Frequency) scheme. Visually, this gold detector can be distinguished from other options by the presence of two coils (circular detectors). They are placed one and a half meters apart. A feature of using such a device is that movement is not a necessary condition.
Pinpointer. Such devices accurately determine the location in the underlying surface where the signal is reflected. The registration of changes or interruptions in the eddy current allows for a precise delineation of the area containing gold.
Only Very Low Frequency and Pulse Induction metal detectors are suitable for searching for gold coins and other items. The other two types can be used to detect metal, but they will produce false positive results. A gold metal detector will also be limited in depth.
Pinpointers are convenient to use during the search for several reasons. The main one is the ability to accurately determine the location of a coin or gold piece of jewelry during excavation. You won't have to do extra work that can be effectively avoided.
Types of metal detectors depending on the type of surface
The loss of gold jewelry and precious stones most often occurs outside the home, which is why manufacturers try to specify the type of underlying surface. It is not possible to use the same metal detector to search for gold in different conditions, as devices may provide distorted results.
It is quite easy to determine the necessary type of detector. Just think about the anticipated search locations and choose one device or another. Today, several options are available on the market, among which the following are particularly popular:
Beach detectors. As the name suggests, these search devices are suitable for finding gold coins and jewelry on beaches. It's important to ensure that the chosen device is water-resistant and has ground balance settings. Soil mineralization (sand) can lead to incorrect location detection.
Waterproof. In this case, the treasure hunter needs to take care of waterproofing. The specifications can vary significantly, but optimal protection is considered to be waterproof up to a depth of 3 meters. This is enough to enter the water and search for lost treasures at the bottom. It's also advisable to purchase headphones that will allow for more efficient search operations.
Deep. When it comes to the operation of a metal detector at depths exceeding 3 meters, it is advisable to purchase this type of device. Water protection and retention of operational properties are the main advantages. Such devices are used for searching for 'treasures' that are buried deep in the ground.
The choice of metal detector should be made thoughtfully, as not everyone is eager to find lost pesos and other valuables in seawater. Hobbyists will find a beach detector sufficient, while specialists in this field should opt for a more serious device.
Basic requirements for devices
A metal detector for gold, which will be used for searching, must correspond not only to the ground surface but also to a whole range of other factors. Ensuring proper uninterrupted operation is achieved by studying the characteristics of the chosen equipment.
In order to prevent the use of the device from becoming a headache, pay close attention to its basic "abilities":.
the ability to effectively discriminate the search target;
minimum acceptable size of the object;
depth of detection of gold coins and other items;
automatic or manual ground balancing.
Target discrimination will be required in order to distinguish a piece of gold from other metals in a timely manner. The presence of such a function is a mandatory condition, since gold items do not have high electrical conductivity. A metal detector for gold without target discrimination will give false signals.
The detection depth will allow finding treasures beneath a thick layer of sand or other types of soil surface. The higher the rating stated in the specifications, the greater the chance of detecting a coin deep underground. It is also worth considering the possibility of adjusting the balance.
Ground adjustment is a function that prevents false signals during the search. The mineralization of ground surfaces can cause malfunctions. In order to avoid wasting time, gold seekers adjust the device automatically or manually.
The best metal detector for gold is a device that can be adjusted to meet your goals. The ability to find small coins and other gold items will be a nice bonus. Only in this way can one gain confidence that the search will be conducted correctly.
A metal detector for gold with a high frequency is better at recognizing coins with low conductivity. Amateurs or professionals should pay attention to this parameter as well. Devices with frequencies ranging from 11 to 22 kHz are considered high-frequency devices.
Choosing a metal detector online
The metal detector will function properly only in cases where the buyer has set the right priorities and carefully studied the requirements for the devices. In order to understand how suitable a certain model is for you, it is necessary to familiarize yourself with the reviews of experienced treasure hunters.
Information about devices can be found not only on the online store's website but also on other entertainment platforms. Data about the operation of the devices from the first hand will help to properly choose a gold detector and go on effective searches.
The features of the devices are listed in the description, so there are no problems with learning. However, it will still be difficult for beginners to understand the new terms. There is no need to despair, as a prepared short list will help to expand the knowledge base:
Discrimination is the ability to exclude unwanted finds from gold. The finer the scale, the easier the search.
Wavelength or the size of the object. The shorter the signal, the higher the detection rate of the sought coins. A high frequency indicates that the wave is short.
Tuning. Manufacturers indicate its presence or absence. The division into automatic and manual tuning can also be found in the description. The ability to combine both options is a priority.
A gold metal detector must meet your goals, otherwise you will be disappointed with your purchase. Making the right choice is assisted not only by the specifications provided by the seller but also by reviews on specialized channels and customer feedback.
If you are not aiming to acquire a metal detector for gold and use it for professional purposes, it is better to ignore the expensive models. The cost of such devices is quite high, so it is advisable to look at the mid-price range.
Recommendations for the use of metal detectors
To make effective use of the new metal detector, it is advisable to familiarize yourself with the instructions immediately after purchase. It will not be possible to understand the operating scheme on your own, as gold metal detectors of different types vary significantly from one another. One should not postpone getting acquainted with the manufacturer's instructions.
Assembly and the first testing should be conducted in safe and comfortable conditions. It is advisable to ensure that experiments are carried out not in the field, but in a well-studied location. Samples of gold and other metals will allow for equipment calibration.
First of all, attention should be paid to the adjustment from the ground. If the stated characteristics indicate automatic leveling, take advantage of this opportunity. The manual adjustment function requires certain skills, so it's necessary to watch training videos.
