The basics of working with metal detector

 

Can any one metal detectors deal with all tasks at once?

 

Most metal detectors are designed to cope well with any type of search, but many can also be used for other purposes. For example, in large parts of the metal detectors for finding gold nuggets “filling” is used with a high rate of gain that helps achieve greater sensitivity when looking for small gold nuggets. And although this is a very useful feature , coin hunters may not appreciate the fact that the device feels every bit of bottled jams trapped underneath the mower.

 

The art of creating metal detectors is the art of compromise. By focusing on the functions, you will be forced to weaken the other. Many universal detectors are not so good in specific search conditions. This output is talk about possible choices with many search engines, as well as clearly and realistically to imagine their own needs during the search. The most important thing is to choose a metal detector, which would be consistent with your style and meet their needs search.

 

This is probably the first question on the list by anyone who buys a metal detector. Unfortunately, the answer to this question is not possible. Each search engine makes the choice depending on their specific requirements, wide range of which can not be satisfied with a single appliance. The first step is to define your search style, level of experience and the time you plan to spend on the hobby. Depending on the results, you can determine the metal detector, which would suit you best in function and budget.
Metal detector with a large number of settings is better than a metal detector where their little?
How much better cost 1000 dollars detector detector cost $ 200, and what is it better?
The answers to these questions are interrelated, so I will try to answer both at once. Generally speaking, the higher the cost of the detector, the more it functions. The more functions, the more settings. The more the metal functions (and settings), the better you can adjust it in accordance with the conditions in which you will have to work with it.
However, the downside of having multiple functions in metal is that it increases the possibility of misconfiguration. Even though you may well set it up in one setting, not the fact that you can do just as well in others. But if the metal detector  is adjusted correctly, it will lose much in depth and sensitivity, and, eventually, on performance can easily give way to a well regulated device .

Digital metal detectors detect coins at greater depth than analog?

The metal detector is digital, does not speak about its underlying characteristics. Once such instruments were the most expensive in the lineup, and engineers tried to equip them the latest electronics at that time. Now, with the advent of more devices available on the market with digital signal processor and LCD displease, range of metal detectors, digital and inexpensive, has expanded. And despite the fact that digital metal detectors are good depth, there are analog models of metal detectors, which see deeper.
You need to remember, and it is very important that the digital device can provide more information about the purpose of using the LCD. But the accuracy of this information is inadequate. Tests in air give good performance on the qualities of the metal detectors are equipped with displays, but as soon as the object is in the ground, many factors intervene and affect the performance of the sensor. The most common mistake: the tabs from cans and gold rings are in one category “objects consisting of alloy metals.
The goal of the Earth also can affect the correct functioning of the appliance. If you decide to purchase a digital metal detector,  all targets that give “good” audio signal regardless of the indicators on the display how do search engines with big experience. Of course you’ll be digging up more garbage, but the number of “good” goals will be higher when such tactics.

Metal detector with the quartz frequency stabilization is better metal detectors without it?

Many manufacturers use quartz in its devices due to strict tolerance of such cavities. If one component of the system is clocked at 15.7 kHz, all other components will run at the same frequency. Flipside admission hard limits is that devices are more prone to cross interference. In other words, the outgoing and incoming signals of two or more metal detectors, working side by side, can mingle and influence each other.

 

At Tesoro to form Metal Detectors working frequency used inductive-capacitive circuit, or a parallel resonant circuit. The capacitor and inductor connected together and radiate the desired frequency. Fluctuations in the condenser and coil create light vibrations working frequency, which reduces the likelihood of cross-talk with other metal detectors Tesoro. However, these fluctuations are so small that they do not interfere with the correct operation of metal detectors Tesoro .

Metal detectors working on multiple frequencies, better than metal detectors working on one frequency?

A parallel resonant circuit, described above, generates a sinusoidal wave (or Sine Wave). These Sine waves are sufficient by themselves and do not have harmonic waves.
Devices running on two frequencies, can combine two Sine waves, but more often uses a rectangular wave. Devices running on multiple frequencies, almost always generate a rectangular wave or converted rectangular wave. Rectangular wave rich in harmonic waves and need more energy to be generated, respectively, battery charging enough for less time. Harmonic waves generated by square waves, can be used as a separate frequency for more information about the object’s type and depth of its occurrence.

About selecting coils for metal detectors.

Why are there so many different kinds of search coils?

On the market today, there are two main types of search coils for metal detectors – Mono and Wide scan (DD). In concentric coils used two round antenna, one inside the other. These coils are used in most detectors designed to find coins, jewelry and relics. Concentric coil have very good discrimination and allow you to easily define precise objectives, is parked as the best signal is always in the center of the coil.
Wide scan coil using two D-shaped antennas, located one after the other. Thanks to this configuration, they are called “DD” coil. Wide scan coil are less prone to interference from soil, in contrast to the concentric, so they typically are used to find gold or to search for relics in places with high mineralized soil. Pin point is back or base of the coil. Once you have chosen the type of coil, it is necessary to pay attention to her size.
There are many different sizes of spools. Each is suitable for a particular type of search, so it is important to choose the right size. Large diameter spool allows you to identify the deeper purpose, but this only applies to large objects, and to small targets, on the contrary, the sensitivity is reduced. Large reels also are more prone to “disguise”. “Mask” in Discrimination mode happens when “good” goals and garbage at the same time are under the coil. If both objectives are very close to each other, then the device discriminates against junk, but at the same time skips and the desired object. This phenomenon often occurs when looking at garbage sites, as well as the foundations of old houses and nearby.
Smaller diameter coils are more sensitive to small goals and better able to localize the signal. Unfortunately, small coils tend to lose in depth compared with their larger counterparts. However, due to the smaller area of coverage, they are not as susceptible to the effect of “masking” the garbage sites.
Introducing exactly where you will “hunt” and for what purposes, you will be able to choose the right reel, to suit your needs. The larger the coil fits  search to search for relics and sites, which usually occur at greater depths. Smaller diameter coil better is finding small targets, such as gold nuggets or decorations, and can also be used to search for coins and jewelry at garbage sites.

What is the difference between conventional coils and reels for underwater search?

When searching in the water most coils are the swim out on the surface. In accordance with the requirements of the clientele, coils are getting easier and easier as manufacturers give their definite form of foam or other kinds of light fillers. It creates inside the coils of air bubbles that push it on a surface and.
For underwater search coil is filled with materials having zero buoyancy when placed in water. This means that this coil does not not swims and drowns in water, allowing underwater search with maximum comfort.

Collected on the secondary market “hot” better than average, and coil why manufacturers do not produce them?

If you look closely at the so-called “hot” coil, you will see that they are a few more of those reels, they are meant to replace. As noted above, larger coils see deeper, but they have a negative quality, which can have a negative impact with some form of search. Many manufacturers already produce coils with a diameter larger than the ones that come complete with a metal detector. They are specially designed by professional engineers for a specific kind of devices and used in electronics. Based on the above, the question arises: Why buy the coils, which are produced in different conditions and with no guarantees?
