Side Effects

You are at a higher risk of undesirable side effects from caffeine if you have more than 500 to 600 milligrams of caffeine per day, which is contained in more than 4 cups of brewed coffee. Some immediate side effects of high caffeine are nervousness, restlessness, upset stomach, rapid heartbeat, muscle tremors and irritability, according to MedlinePlus.com. In the long term, drinking a lot of caffeine throughout the day might lead to a vicious cycle of insomnia and fatigue, wherein you consistently lose sleep because of caffeine's effects, but then you need to drink caffeine to be alert during the day.

Hypersensitivity

Your body should be able to tolerate about 200 to 300 milligrams of caffeine a day - equivalent to about 2 to 4 cups of brewed coffee - unless you are sensitive to caffeine. You might be more sensitive to caffeine if you are prone to stress, have high blood pressure, have headaches often, have an irregular heart beat and stomach ulcers or acid reflux, according to MedlinePlus.com. If you are extra-sensitive to caffeine, a single cup of coffee could prompt undesirable effects, such as restlessness.

Pregnancy Risks
You may increase your risk of fertility problems if you are a woman who has a lot of caffeine. Caffeine reduces muscle activity in your fallopian tubes, which are responsible for delivering eggs from your ovaries to your womb, according to the May 26, 2011 issue of the "British Journal of Pharmacology." Caffeine can also increase breastfeeding because it crosses the placenta and reaches the fetus. Because the fetus has an immature metabolism, caffeine may linger in its system and build up to toxic levels. You may be at a higher risk of miscarriage and delivery of a low birthweight weight if your caffeine intake exceeds 200 to 300 milligrams per day.

Addictive Properties

Caffeine dependence can occur, according to 1994 study published in The Journal of the American Medical Association. In the study, researchers determined that caffeine drinkers had an average of 357 milligrams of caffeine per day showed classic drug dependence signs and symptoms such as a higher tolerance for caffeine with frequent use, a persistent desire or unsuccessful attempt at limiting their intake, withdrawal symptoms when they cut back on their intake and choosing to continue consuming caffeine in spite of the knowledge that caffeine might cause them psychological and physical problems. Common caffeine withdrawal symptoms - headache, fatigue, irritability, trouble concentrating and depression - have been observed at persistent intakes as low as 100 milligrams per day, but they are more common with higher levels, according to the Linus Pauling Institute.

Caffeine and its influence on personalities withdrawn

Caffeine is one of the most widely used stimulants in the world due to the ease of consumption, as it is found in various alcoholic beverages and soft drinks, as in chocolates, tea, coffee and a multitude of medicines.

While its invigorating and energizing property is well known, caffeine could also accentuate sensitive personality traits , causing greater states of shyness, anxiety or irritability. Therefore, it is appropriate to know the influence that this nutrient could have on people since they are in the womb until adulthood.

Prenatal exposure

It is very common for pregnant women to avoid caffeine consumption during this period and for good reasons, otherwise it could be causing stress in the baby, in addition to causing long-term effects that would be reflected in a set of features such as fear, withdrawal, anxiety or shyness in the child's personality .

Although the professionals do not have certainty on this point, it is estimated that these negative effects of caffeine on the pregnant child may be due to the interference that occurs in neuronal development and the release of neurotransmitters.

Sensitivity

These sensibility traits , which could be resolved both in withdrawn attitudes, shyness or inhibition, as well as in cases of irritation and easy anger, are estimated to be found in more than 20% of people, who upon receiving certain stimuli respond with different forms of behavior. One of these stimulants is caffeine , which could trigger and settle these traits in sensitive people.

Intensity trait

Caffeine can even intensify the sensitive features of people, may cause greater states of withdrawal in naturally shy individuals as situations of anger in irritable people.

For this, according to the Spanish journal of psychology, the intake of 2 cups of coffee per day would suffice, so it is very important to identify if any of these sensitive features integrate our personality to, if so, avoid or reduce to the maximum the consumption of foods with caffeine .

Attention and reaction

Caffeine could also have "positive" effects, such as an increase in concentration and a stimulating effect for the whole organism, that's why caffeine is consumed willingly by timid or introverted people.

If several American studies are considered, the consumption of about 7 milligrams of caffeine daily is a good stimulant to improve performance without leading to major complications.

The last word will be given by a medical professional, who will recommend if the consumption of caffeine is the most recommended for your personality or mood. Anyway, a good advice is always to govern moderation.

What Are the Dangers of Caffeine Abuse?

Many people drink caffeinated drinks as coffee, tea and energy drinks for a boost of energy to start the day or stay awake and focused throughout the day or evening. Caffeine stimulates your central nervous system, so it can make you feel more alert and energized, but excess use of caffeine can result in a variety of negative side effects.



Keurig Coffee Lovers' Collection Sampler Pack, Single Serve K-Cup Pods, Compatible with all Keurig 1.0/Classic, 2.0 and K-Caf? Coffee Makers, Variety Pack, 40 Count

Caffeine Intake

Most individuals can consume 300 milligrams of caffeine per day, which is considered moderate intake, without experiencing serious side effects. Caffeine content for beverages can vary depending on the size and brand of the drink, but in general you can drink approximately three 6-ounce cups of coffee, which equal 300 milligrams of caffeine. Tea, cocoa, soda, and energy drinks may also contain caffeine, and intake of these beverages should also be limited. Non-prescription medications containing caffeine include Excedrin, 65 milligrams, Anacin, 32 milligrams and maximum strength Midol, 60 milligrams, according to the University of Michigan.

Physical Effects of Excess Caffeine

Ingesting large amounts of caffeine, 1,000 milligrams or 6 cups of coffee per day, may lead to physical side effects caused by habitual use and the stimulating effects of caffeine. Heavy use and abuse may result in restlessness, rapid heart rate, nausea, muscle tremors, insomnia, and, according to the University of Michigan, problems with conception. Lack of sleep from caffeine use can lead to ongoing sleep disturbances, fatigue, and a decline in physical performance and energy levels.

Habitual Caffeine Abuse and Mood

Caffeine abuse can be habit forming. If you abruptly stop caffeine intake, you may experience unpleasant withdrawal symptoms and mood changes. Caffeine abuse lead to psychological symptoms such as anxiety and irritability, and withdrawal from caffeine causes marked nervousness and depression leading to reduced motivation and sleeplessness.

Expert Insights

McKinley Health Center recommends, if you are consuming large amounts of caffeine and suffering from symptoms, you should gradually reduce your daily consumption by selecting beverages with a lower caffeine content and alternating coffee or teas with decaffeinated or caffeine-free options such as decaf coffee , herbal teas or water.

Caffeine consumption: what you should know

250 milligrams of caffeine a day awakens the brain, helps in concentration, relieves excess stress and can even help you live longer.

In any case, it is very important that you bear in mind that, like all things in this life, excessive consumption is always harmful. You should always control your caffeine intake and know when you should stop, otherwise you will have a counterproductive effect.

Caffeine is addictive , and if your consumption is becoming an addiction, do not hesitate to stop using it. In this case you will recognize the side effects easily, such as dehydration, problems falling asleep, anxiety, upset stomach, etc. You should not consume caffeine during pregnancy .

Decaffeinated coffee

Although it seems very obvious and you think decaffeinated coffee has no caffeine, this is a hoax. The idea of ​​a coffee with the flavor that you like so much but without the effects of caffeine sounds good. However, decaffeinated coffee still contains caffeine. Of course to a lesser extent, but it does.

Soft drinks that are not cola

The secret of cola soft drinks and their caffeine content is something we all know. On the other hand, did you know that almost all soft drinks and sodas in other flavors have caffeine? Well that's the way it is, and even in other beverages like some root beer brands, there is a high content of caffeine .

Chocolates

You already know that cocoa has many health benefits and that chocolate is made from cocoa. However, chocolates are another source of caffeine that can also help you with some extra energy. Caffeine is mostly found naturally in cocoa beans and combining it with a soft drink will keep you more awake and active.

Frozen

Who does not like ice cream? It is ideal for summer, it is soft and delicious but, in addition, it has caffeine. You can even order a chocolate ice cream to add, and even many brands of ice cream also offer coffee flavor, so you can keep adding and make an energizer even more powerful.

Weight Loss Pills

While caffeine will not help you in anything to lose weight, strangely the manufacturers of diet pills add certain caffeine content to their products. So if you are looking to lose weight and are taking pills to lose weight, keep this in mind. Whether you want a boost of energy or if you are having trouble sleeping, you can find something interesting by looking at the ingredients in the leaflet of your pills.

Medications to relieve pain and flu

Many medications to relieve pain, like a large number of flu shots or flu pills, have certain caffeine content. A little of it can alleviate the pain and remove a discomfort. However, excessive consumption of caffeine can generate your own discomfort and, for example, a headache .

Energy drinks

Energy drinks have high caffeine content and it is quite obvious. There are even some brands that are prohibited from selling in several countries for that reason. The vast majority of energy drinks are based on guarana, and if you did not know the guarana is also a fruit with a high concentration of natural caffeine , especially those grown in Brazil.

Refrescantes buccal

Mouth fresheners in aerosols and some chewing gums have a certain caffeine content. It's actually a strange thing, but some brands of chewing gum and other mouth fresheners add caffeine to their products. Maybe it's a sales strategy (remember that caffeine is addictive) but the truth is that this substance is present there, so always control the ingredients of what you consume.

Sunflower seeds

That's right, sunflower seeds are a natural source of caffeine . They are delicious, nutritious and very healthy so they can be easily used in many meals. In addition to caffeine, they contain several proteins such as taurine and lysine, as well as vitamin E and B6. What are you waiting for?

In most cases, the caffeine health benefits were realized by those who consumed moderate coffee / caffeine amounts. Also in some of the studies above, the caffeine is concentrated and applied directly to the body area being researched, ie cataracts and baldness etc. Therefore, dietary caffeine would not produce the same results.

The British Medical Journal published a study that reviewed 201 studies concerning coffee and caffeine. The scientists concluded that there was no evidence of the health benefits of consuming coffee outweigh any risk involved.

We can conclude that caffeine consumed via natural sources is probably the best since many of the benefits of caffeine are probably largely due to the high antioxidant levels found in regular coffee and tea.

Benefits and dangers of caffeine

Caffeine is a substance that can be found in several products, especially liquids, that we consume every day. Among these drinks that contain caffeine we can find coffee , tea, cola , chocolate and some medicines. Caffeine is the most used stimulant on the planet, so we must know what are the benefits of caffeine on our health and the damage it can cause.



The Original Donut Shop Keurig Single-Serve K-Cup Pods, Regular Medium Roast Coffee, 72 Count

Overview of caffeine consumption

This substance is usually used as a stimulant. For example, coffee consumption is very typical in people who have to study or work at night, so that, through the caffeine it contains, the nervous system is stimulated, helping people to stay awake and focused .

Some people are more sensitive than others to the effects of caffeine , to the point that some people drink coffee and keep them awake and there are other people who, despite taking several, do not have the same effect.

But caffeine has, in addition to many advantages also has dangers and disadvantages, as it is terribly addictive. We are going to detail a little more the subject of the c afein and its effects on our health.

Benefits of caffeine

Among the benefits of caffeine we mentioned, apart from how nice it is to have a coffee or a tea in the morning, the following:

•     It seems that caffeine is a memory enhancer, as well as a great help when we have to be alert. For example, when driving at night, to study for hours, when we get up and go to work, etc.
•     Caffeine stimulates hair growth and evidence has also been found that it detoxifies the liver and cleanses the colon.
•     After intense exercise, caffeine relieves muscle pain or the famous stiffness. It also helps alleviate the effects of depression through an increase in dopamine in the brain.

Damages of caffeine

Among the most obvious detriments of caffeine is that it is a very addictive substance and can create quite important withdrawal syndromes, causing irritability and nervousness.

It is considered as an excess of caffeine that can produce undesirable effects on health take more than 500 or 600 mg of this substance daily. The effects of this excess can be insomnia , increased heart rate, nausea, muscle cramps . Excess can also have emotional and psychological effects such as anxiety, irritability, nervousness, etc.

If you are suffering from these symptoms, observe the amount of caffeinated liquids you drink per day, not only coffee, but tea, cola drinks or any medication that carries this substance among its ingredients. Go reduce the consumption of these drinks until you can balance and avoid these undesirable effects on physical and mental health.

Does caffeine harm our health?

    It helps us to be more alert and some studies relate their consumption with a better intellectual performance. However, caffeine can also raise blood pressure or cause insomnia. Know what food is present and how much we can eat a day so that its effect is not harmful to health.



Nespresso Variety Pack Capsules, 50 Count

Caffeine is an alkaloid that is obtained from the seeds and leaves of coffee, tea and other vegetables. It is a stimulant of the central nervous system that makes us feel more energetic and alert, relieves fatigue and drowsiness. According to the European Food Information Council (EUFIC) , the adult population of Europe consumes an average of 200 mg daily (100-400 mg) of caffeine.

Where can we find it?

Caffeine is present in coffee, tea, some soft drinks and chocolate. The amount of caffeine in these products varies according to the size of the portion, the type of food and the method of preparation.

The approximate amounts per serving are:

•     Coffee (per 150 ml cup) toasted and ground-instant: 80-60 mg caffeine / serving
•     Decaffeinated coffee (per 150 ml cup) both roasted and ground and instant: 3 mg caffeine / serving
•     Tea (per 150 ml cup): 40 mg caffeine / serving
•     Cola (per can of 330 ml): 30 mg of caffeine / serving
•     Chocolate in pill (50 g): 20 mg caffeine / serving

Caffeine and cardiovascular health

Caffeine causes an increase in blood pressure and heart rate, therefore it is advisable to limit its intake in patients with cardiovascular diseases and / or hypertension. In addition, according to the EUFIC, a high consumption of caffeine is often closely linked to an excessive consumption of coffee, which in many cases is linked to other factors that influence the possibility of developing these diseases, for example, smoking, inactivity physical, the consumption of saturated fats and the abuse of alcohol.

On the other hand, some studies have analyzed the effect of caffeine intake and the increase in cholesterol levels without finding a direct relationship.

How much quantity should we take?

A moderate daily consumption of caffeine (up to 300 mg, the equivalent of two cups of coffee) is recommended by experts. Control the amounts we consume is important because an excess of caffeine can cause:

•     Increased heart rate
•     Arrhythmia
•     Increase in blood pressure
•     Irritability
•     Insomnia
•     Restlessness
•     Nervousness
•     Diuresis and / or diarrhea
•     Sickness

Stop taking caffeine in high amounts can cause withdrawal syndrome, which can manifest in headache and loss of mood, although this usually exceeds in a few days.

In addition, those with difficulty sleeping should limit the consumption of caffeine to normal amounts and avoid ingesting any product that contains it in the previous hours the sleep period.

Caffeine and intellectual performance

Human Psychopharmacology: Clinical and Experimental has published a study, carried out by members of the University of Barcelona and the Pi i Sunyer Biomedical Research Institute of the Hospital Clínic of Barcelona, ​​which shows that the combined consumption of caffeine and sugar has certain effects on the system human cognitive, as the improvement in attention, in learning and the consolidation of verbal memory.

In summary, moderate caffeine intake in healthy people is not harmful to health. Now, if you have cardiovascular disease or suffer from hypertension, you should limit your consumption. In any case, do not forget to always take a balanced diet and exercise!

What is an active metal?

Active metal is defined as that which has low ionization energy , that is, that metal that tends to lose electrons easily to form cations 1 . This behavior is due to the disposition of its valence electrons and causes the active metals to react more strongly and quickly than other elements.

The active metals are in group IA (or group 1) of the periodic table, the first column on the left side, a group much better known as alkaline metals . These are:



New Home Innovations NHI Classic Metal Detector for Adults & Children - Best Metal Detectors for Kids 10 and Up - Waterproof Coil Detects All Metal

• Lithium (Li)
• Sodium (Na)
• Potassium (K)
• Rubidio (Rb)
• Cesio (Cs)
• Francio (Fr)

Hydrogen is in the top position of group IA but is not considered an active metal , although it shares many characteristics with them.
Group IA and group IIA of the periodic table (alkaline metals and alkaline earth metals respectively) form the so-called reactive metals, being the most reactive metals of all, and it is very common to talk about active metals and reactive metals in an indistinct manner. refer to both groups.

The elements of group IA, which is generally referred to specifically as active metals, have a single electron in its outermost orbital (a single valence electron) with a configuration of the ns1 type :

• Li    [He] 2 s 1    Rb    [Kr] 5 s 1
• Na    [Ne] 3 s 1    Cs    [Xe] 6 s 1
• K    [Ar] 4 s 1    Fr    [Rn] 7 s 1

Given the low electronic affinity of these elements and their low ionization energy, they tend to yield this electron rapidly forming a monopositive cation (type M + ).

For example, if we put metallic sodium in contact with water, a violent reaction takes place in which the sodium loses an electron to form the Na + cation; the water molecule breaks forming OH - and H + ; OH - together with Na + forms sodium hydroxide (known as caustic soda ) remaining in solution; the H + on the other hand forms gaseous hydrogen (H 2 ) accepting the electrons yielded by the sodium:

2Na (s) + 2H_ {O} (l) → 2Na <+> (aq) + 2OH <-> (aq) + H <2> (g)

As you descend through group IA, the electropositivity and reactivity increase. The first lithium ionization energy, which is the first in the group, is 520.2 kJ / mol, and that of Francio, which is the last, is only 380 kJ / mol.

The Francio, therefore, is the active metal of greater reactivity , although it is very unstable. Its half-life is only 22 minutes. The element immediately superior to the francium, cesium, would be the most reactive element with a stable cation.

The high reactivity makes it very difficult to find active metals in a pure state in a natural environment , as they react easily with water, oxygen and other substances in the air to form other compounds.

This characteristic forces the scientists who work with these elements to keep them in strictly controlled conditions and isolated with some inert substance for them. It is usual for some type of oily substance, usually mineral oils , to be used as an insulator, which prevents the passage of oxygen and water vapor from the air.

The high reactivity of the active metals makes them dangerous in their handling but also makes them very useful. The active metals are used in controlled chemical reactions for the manufacture of a wide variety of products that we can find in our daily lives.

For example, Lithium is used in the manufacture of batteries, known as Li-ion batteries (a type of battery or dry cell ), widely used in gadgets and personal technology.

How to find gold in Lleida (and have fun with the family)

Gold has been dissolving in the original core of the Pyrenees since the Paleozoic: about 300 million years ago. The erosion was diluting those rocks with their minerals on the Segre River, that's why there is gold in this river. And they have returned the activities to look for nuggets of gold in the Segre, especially at the height of Balaguer (Lleida). Gold fever returns, but without hurry, just to have fun and enrich yourself with the experience.

The Segre River is considered a gold river. The Segre Gold Interpretation Center divulges the history and characteristics of the river. One of the most intense passages of its history has to do with the presence of gold.



URCERI GC-1028 Metal Detector High Accuracy Waterproof 2 Modes Outdoor Gold Digger with Sensitive Search Coil LCD Display for Beginners Professionals, Yellow

The Arabs who conquered this territory were not expelled until the 12th century, well into the Middle Ages. The Christians could not appropriate this land because the Arabs paid the troops with the gold that was extracted from the Segre. It was a nucleus with natural resources.

Today the extraction of gold from the Segre is one of the most fun and enriching activities of the Segre Gold Interpretation Center. During the activity, gold locating and extraction techniques are learned. And if you can find it, you take it home. The 18-karat gold gram is paid at 28.95 €

How gold is extracted from rivers

Gold is a heavy metal: gold remains while other metals are carried by the river. It is not a question of weight, but of density. The density expresses the relationship between mass and volume. It is the amount of matter in a volume. A small nugget of gold is denser than any other metal.

Once a sedimentation zone is located, as taught from the Museu d'Interpretació, it's time to put on your boots and take the punt. A handful of earth and stones are collected with the tray. Once in the river, in favor of the current, the contents of the tray are caressed with water.

It is a task that requires patience and a certain precision. A few turns to the punt and a small impulse to the outside: the objective is to expel the stones, the earth and the lighter minerals. Gold is one of the densest elements in the universe, so if it is, it will remain in the container.

After each exercise, it will be enough to look at the filtered contents of the pan. You have to be alert: gold nuggets can be tiny. If you choose a sunny day, you can identify them more easily by the brightness.

If you want to learn more, we recommend a trip to Balaguer and its Museum of Interpretation of the Segre . We also link the work of Dr. Manuel Viladevall Solé, geological engineer: The prospection of gold and other dense mineral pleasures .

Why is gold measured in "carats"?

The Greeks have gone down in history as the inventors of myths, democracy and philosophy. With so many and such great attributes, his contribution to jewelry has gone unnoticed.

Carat is a derivative of the Greek word keratio : "carob." A carat is a carob tree seed. As you hear it. The Greeks realized that algorrobo seeds always weigh the same, so they used them as a measuring instrument. The Romans adopted the seeds in their weight scales: a gold coin weighed the same as 24 seeds of carob (24 carats).

Today the "carat" of gold indicates purity, not weight. That is to say: the gold alloy with copper or silver. An 18-carat piece contains 3/4 gold and 1/4 other mineral. But in other jewels, like diamonds, the carat expresses its weight. Look where you look, gold is always special.

How to get metal in Ark Survival Evolved? Farmear Method

We can find metal in many places in the game. Although normally the best locations are high up in the mountains, in caves and even on the seabed.

Metal is one of the most important resources and it is necessary to craft objects such as a radio or compass. And when we get metal ingots , its uses multiply and it will help us to make weapons, armor, and a long list of valuable objects.



Bangtan Metal Detector pinpointer Portable Handheld Profession Metal Detector Updated Buzzer Vibration Alarm (GP Pinpointer)

Obviously we can go with our metal pick , the best tool for this purpose. If we want to get larger quantities we can go with an Ankylo , which extracts faster and has a good load capacity. But if we really want to get huge amounts of metal, then we explain the best method to farm in the game.

What do we need to make metal in Ark?

We need a Quetzal, since it will be our means of transportation. Also an Ankylo who will be the one who chops the metal stone. And finally a structure so that the Quetzal can transport the Ankylo while it stings stone.

3 fairly simple things that will multiply our extraction and collection capacity.

Method to get metal in Ark Survival Evolved

The reasoning of the method is that the Ankylo alone can collect metal up to a limit because it weighs. But if we carry it on a Quetzal, its load capacity increases without limits.

First of all, the recommendation is to remove the melee damage of the Ankylo . Since in this way we can collect metal faster.

The first step is to build the structure on the Quetzal . We will have to put 2 foundation on its back and a wooden ramp that hooks to the foundation and reaches the ground by one of the sides.

We get to the area of ​​the ore and put the ankylo on the edge of the ramp so you can break stones and collect metal . But without moving it. All the movement has to be borne by the Quetzal , who is the one who bears the burden of the resources that Ankylo collects.

And this is the method. In this way they can get more than 5,000 metal in just 10 minutes.

How to turn your Android into a metal detector

Has it ever happened to you that you drop a clip, a pin or a safety pin and you are not able to find it ? In general, anyone would use the flashlight of his cell phone and his naked eye, but in reality everything is much simpler, because yes, in your pocket - or in your hand, depending on where you read this - you have a metal detector that works extraordinarily well that can get you out of more than one hurry. Do you want to know how to turn your Android into your metal detector? Well, keep reading!

All, or almost all Android smartphones have a magnetometer , a sensor capable of detecting and measuring electromagnetic fields. With the application "Metal Detector" you can use that sensor to find different metal objects around your house - or the typical ring / pendant / bracelet that always falls on the beach - easily. You just have to download it, calibrate it and move your phone.

To calibrate it, simply move the phone up by making an eight several times (like when you calibrate the compass). You will see that you have a standard measurement of about 45μT and that the graph remains stable. However, if you bring your mobile to a metal object an alarm will sound and you can check the intensity of the magnetic field, so you can find any lost object (as long as it has some metal, of course).

The application works really well, and in the tests that I have done with my Galaxy S7 edge (it is burst and it is the one I use for all these "experiments") it has proven to work better than I expected . I have done some tests with objects from my room such as the computer case, a red metal drawer and a shelf and, in fact, when it is metallic the phone starts beeping while being wood or other material does not whistle at all.

It is true that it does not have the sound that we all recognize from metal detectors , but if you have fallen a pin on the ground you will appreciate having this app at hand. It's free , by the way.



Better metal detectors to find gold nuggets in rivers or mines

Normally, metal detectors for gold prospection have a frequency of 15 KHz to 18 KHz, but in 2017 that changed for the better, high frequency coils started coming out, said coils could reach 59 KHz and others until 85 KHz.

This high frequency in the coils is a radical change in the search for gold with metal detectors, you can also use the detector in parks, because you could find small gold tendrils, which would be impossible for any other metal detector.

These high frequency coils work without problems in very mineralized soils, we can also detect near high voltage towers without suffering any interference.

The only disadvantage would be that we would lose depth, but if you want to find things like ultra thin coins or that are buried vertically, gold tendrils and native gold, buy a high frequency metal detector.

Buy the XP Deus detector by parts and try to buy the headphones that are updated in the V-4.0 version, because the previous versions do not work with the high frequency coil.
