Often asked: how to set up these metal detectors for effective search?
More experienced search engines will tell you why there is a need to set up the X-Terra, an already simple and understandable metal detector, turned it on and started working. Possibly, but novice users will benefit from learning a little more.
Discriminator setting
Discriminator - allows you to distinguish non-ferrous metals from iron with a certain degree of probability. It should be noted that there is no such metal detector in the world that would 100% distinguish metals, for example, gold from aluminum, etc., or find only gold. If such a device existed, it would be a revolution in treasure hunting and I would have long ago lived somewhere in the Canary Islands for my own pleasure. And metal detectors with a 3d screen or displaying outlines (contour, photographs) also do not exist!
Metal detectors identify the type of metal by the electrical conductivity of the metal, but this method does not provide 100% accuracy for recognizing non-ferrous metals, only allowing a good distinction between iron and non-ferrous metal. More modern, multi-frequency metal detectors, such as E-Trac, in addition to the electrical conductivity, also check the inductance of the metal, allowing you to more accurately distinguish metals. But today (2014) E-Track is not the most advanced device. the 3030 model (zozo) won the first place.
Metal detectors X-Terra 74 and X-Terra 705 have 28 segments of discrimination in increments of 4 from -4 to 48. Iron occupies 4 segments from -8 to -2. Color targets from 2 to 48. The more segments on the metal detector's discriminator scale, the more accurately you can set the metal detector to ignore unwanted targets. The accuracy of determining the type of metal also depends on the depth to the object. The greater the depth, the more difficult it is to determine the type of metal, soil interference interferes and the discriminator may be mistaken.
For example, it was noticed that at a depth of more than 15-20 cm, the discriminator on silver coin weighing only 0.2 to 0.6 gr. times of Ivan the Terrible (in the common people scales) does not give a constant positive color signal, but a variable one, alternating positive readings with negative -2 (iron). So if you're hunting scales, make the -2 discriminator segment visible.
Working on the beach
You can set the metal detector's discriminator to ignore common pull tabs from aluminum cans, corks, etc. This will help save time and effort. But you need to understand that the discriminator checks the target only by the electrical conductivity of the metal and some jewelry can have exactly the same conductivity as corks. Ignore only frequently encountered items.
Working in the old days
ignore only iron, in such places there are traffic jams, etc. are rare and you should not ignore them, otherwise you will miss a lot of interesting things: crosses, rings, etc., they do not have constant conductivity, as they are made of different metals and have different shapes.
On heavily rusted targets, for example, rusty iron corks from Coca-Cola or beer, the detector will give a signal very similar or even indistinguishable from copper coin. This is due to the aging of the metal, or more simply, rust and the creation of oxide around the target. Since rust is not iron, but iron oxide, the metal detector is not able to correctly determine the type of metal.
When digging out such a target, the signal may disappear, since you have broken the halo (rust around the target) and the metal detector, with the discriminator turned on, will no longer send a signal to the iron target. At the same time, it may seem to you that the goal is simply lost. Switch the metal detector to search for all metals and make sure that the target is really iron and it is not worth continuing to search for it.
All metal detectors, without exception, will definitely give a signal to large iron targets the size of a tin can - dig! And it is absolutely justified. A metal detector is not an x-ray, and it can shine through, for example, an iron can or cast iron and tell you what is inside. Therefore, a large iron target will have to be dug up and make sure what is inside. Naturally, you will dig up not only cast irons, but also other antiques that may be of considerable interest.
Sensitivity setting
The sensitivity setting determines the depth and ability to find small targets. The higher the sensitivity is set, the higher the detection depth, but at the same time, the more interference from the ground, therefore, the metal detector is less stable.
You hear short, erratic false signals similar to the target, which greatly interfere with smooth work in tall grass or in the bush. The sensitivity should be set smaller, within 22-24 divisions, then false signals will disappear. On grass-free areas, sensitivity can be increased. There is no constant constant that I can recommend, learn from my own experience.
Ground balancing x-terra
The most important technical function of any metal detector is the ability to decouple from ground interference. If the metal detector does not have such a setting, then it is more of a beach metal detector than a treasure hunt.
Since we are searching not in the air, where there is no interference, but in the ground, which is replete with all sorts of interference that prevents the penetration of the electromagnetic signal from the coil into the soil, the detector must be able to ignore soil noise and find the objects we need among them.
The better the metal detector copes with ground noise, the higher its detection depth and sensitivity. Metal detectors X-Terra 74 and X-Terra 705 have both manual and automatic ground balancing, which allows you to work on the heaviest mineralized soils, clay, salty soils, baked bricks.
If you want to find targets deeper than others, don't be lazy, tune into the ground as often as possible. The frequency of balancing depends on the mineralization of the ground in your search area.
If the readings during the mineralization setting practically do not change and remain within the limit of + - 5 units, then the soil on which you are searching is homogeneous and you can repeat the setting as noise or false positives appear. If the ground is not homogeneous and readings constantly change during ground adjustment, it is better to turn on automatic ground adjustment.
The metal detector will independently adjust to the characteristics of the soil, always maintaining maximum sensitivity. Auto tuning has one feature, knowing which you will avoid missing deep shallow targets. For example, a flake coin at the maximum depth gives a very weak, weak, short, barely perceptible signal.
When automatic ground adjustment is enabled, such a signal may disappear after several wires over this target, since the machine will consider such a signal as mineralization and cut it off. Note that the auto ground balance on/off button is located on the front panel and is always easily accessible, and it's not easy. If you hear such a weak signal, turn off the automatic setting, the detector will go into manual mode without changing the ground level, allowing you to hear this target.
Having dealt with this goal, you can again easily, with one keystroke, turn on automatic ground balancing and continue your search.

Detuning from electrical interference.
The stability of the metal detector, its depth and sensitivity are affected not only by soil interference, but also by electrical ones. Any metal detector operates at frequencies from 1.5 to 100 kHz, and if there is a similar source of frequencies nearby, your detector will receive them, which will not allow you to successfully search.
Interference can be from a nearby working metal detector of a friend, your radio station, power lines, etc. Simple metal detectors do not have the function of detuning from interference, which does not allow them to work successfully in a rich area next to a friend, attic, basement or at a treasure hunt meeting. Rich untouched areas remain under the power lines.
If interference occurs, the device will start to convulsively emit short, false signals. Do not be afraid, go to the menu and switch the frequency of operation and the interference will immediately disappear.
Choosing a place to study.
If you are just learning how to use a metal detector, choose a place for training with a minimum amount of metal debris. Don't start your first lessons in Grandma's garden, most likely here your detector will be beeping like crazy due to the abundance of all kinds of small metal debris that you cannot see. Most often, stove ash is poured into the garden to fertilize the soil, which contains not only nails, but also other small household metal debris. Don't start your studies at the beach, in a city park, at a construction site, or at home by exploring an attic or underground. Choose the nearest arable land for study, or even better, a long-abandoned village.
Function for finding very small targets and gold nuggets
Metal detectors X-Terra T74 and X-Terra 705 are universal and combine two metal detectors: a treasure detector and a gold nugget detector. Metal detectors for searching for treasures, coins, rarities do not need super sensitivity to small targets, it is enough to find tiny coins, otherwise, when increasing the sensitivity, you will have to dig out a lot of small unnecessary items, such as shot and other debris. But for the search for gold nuggets, on the contrary, the main thing is sensitivity to very small objects smaller than a match head. After all, there are many, many fewer large gold nuggets than small ones, and the discovery of even a tiny nugget can indicate a gold-rich area.

How to find target size on x-terra 705 (74)
I tried to make a short video lesson for you on how to find out if your goal is big or not. Two not tricky ways will help you more accurately find out the size of the detected object. 1. raise the coil above the ground and if the signal does not disappear, then the target is clearly larger than the coin. 2. use the pinpointer (center of the target) and you will know the dimensions of the target by the sound.

Where to buy x-terra 705
Grater 705 can be bought at a metal detector shop in MoscowToday's article is intended to help all owners of the Minelab x terra 705 metal detector - in my opinion, the best semi-professional device. We started digging with Grater 34, then there were 305, 505, and finally I bought a 705 model, I took a used one for 21,000 rubles. And what can I say - finally, the number of finds has increased significantly. So if you have money, you should not take the 505 model - take the seven hundred and fifth or even better - immediately E-track (but it is one and a half times more expensive). We always go to dig in a crowd, in the team we have both a safari and an etrak, when we walk around the field nearby, we always try to compare the signals.
Of course, 28-frequency converters determine the signal better, you even feel that they are more powerful, they hit deeper, and when, for example, a coin is next to a piece of rusty iron, they rebuild exactly the coin signal more clearly. This is so, by the way. Well, let's take a look at the 705 grater - in general terms, I will tell you my impressions of the work of the metal detector, how it is in depth, according to our tests in the ground. And then, why do we need unreliable air tests? You need to check the MD in the ground on coins, period!
So, for starters, I’ll tell you about the VDI numbers - although it’s considered noob to look at the display, we all look and you know, sometimes we already initially guess what’s under the coil. Numbers, coupled with sound, say a lot.
Let's go over the numbers and the types of goals they show:
44 - let's start with the steepest indicator, this number, together with a high tone (but not the thinnest, when a sheet of aluminum is under the coil) is guaranteed to allow you to raise an old royal copper coin - a lot has been raised by 44 kopecks, kopecks and 3 kopecks of Nikolai, Alexander and Paul. The same goes for nickels, but keep in mind that if the nickel lies very close to the surface, then the device may show an “overload” - such as a large metal object. If you walk on all metals, you will understand where the iron is and where the non-ferrous metal is (in case of overload). But most often a clear signal with numbers vdi 44 is a royal copper coin. Always, as soon as you hear a good "coin" sound and the number 44 on the display - the heart starts beating faster))
40 - almost the same, sometimes shows aluminum. Oxidized cast iron hitting non-ferrous metal is also a common occurrence.
36 - these numbers came across pennies, very often vodka corks, even more often than coins. And of course, silver - when they raised a treasure of hundreds of coins, they all first showed 36, as soon as you remove the top layer of the earth, the number immediately rises to 40-44. They hooked the top of the treasure with an ordinary 34 grater, and they knocked out the place clean already with 705, on which they put a mono-coil. For in the treasure were small silver 5 kopecks (expensive pancake, 2500 a piece on average). More details in our.
Also, iron rings constantly ring at 36, somehow they got tired of digging them in the tract.
But what to do, a coin signal, though later they learned to determine them - the depth of the rings is always 1 arrow, you dig once - there is no target, and a depth of 5 cm means a ring. If the sound is very high, then it is likely that there will be a wire (their old aluminum, thick). Modern wire hits 30-32.
24-28 are Soviet coins, here the sound will be lower, not as sonorous as that of royal coins. Also 28 are vodka corks from the 90s - which are soft (the sound is the same as on "tips" - a low, thick baritone, so to speak). At 36 - hard rigid plugs. Also, these figures come across metal-plastic - crosses, folds. Those things where there is some kind of alloy with copper, and not pure copper, as in coins. Bronze and other copper alloys. Also, sometimes the tips broke through at 20-24.
4-8-12 is a “golden” signal, but here you need to listen already, for gold the signal is very high, and for example, for foil, it is low. I remember once I caught a 4-8 signal, a low tone, but my heart beat so fast, because the sound was pure, without “hoarseness”. It turned out to be foil from kefir (you know, such ancient bottles with a thick neck).
And of course, use the “polyphony” mode, if you switched to a 705 grater from younger models with mono sound, then immediately start getting used to polyphony, there are much more possibilities. And if you still use the right headphones, then the sound gamut will play even more colorful. And then you will more often guess valuable signals and there will be more finds. Well, you can get used to the 705 grater in just a couple of trips. Cool metal detector, which is a significant competitor to professional models. At least with graters, we often “did” both e-truck and safari. But they weren’t born out of the blue either, many times when simultaneously checking a la “guess what will happen here”, the 28-chastotniki showed a coin, while 705 was mistaken and punched into ferrous metal. It all depends on the position of the coin, E-Truck and Safari are better at cutting a coin on its edge. And in this regard, they are cooler. But one has only to hang a low-frequency coil on the seven hundred and fifth and it immediately increases the feel for coins on the edge.
Oh yes, in depth in the ground:
It was possible to raise royal kopecks from 28-30 centimeters
Dvushki also from 30
Nickels were already pulling from a steeper depth - exactly 40 centimeters, when only from the second and even third ejection of the earth they caught a coin.
Tips 5 kopecks - easy from the fiskar bayonet, this is 25 centimeters on average.
What can I say - the discree here is excellent, the depth is decent, a simple and understandable device. For my money, I don't need anything else. At the moment I'm digging with him and everything suits me. I definitely recommend.
Here, for example, - I dug up the most coins, excellent three-ruble notes and copentos. Okay then let's go.
The "Target Identification Stability" mode is rather poorly described in the Russian instructions
I dug a little on the official website - I quote verbatim a clipping from the fake. my translation. comments in italics are mine.
How the "Target Identification Stability" or "+" mode works
In highly mineralized soil, an abnormally strong ground response can affect how the detector displays the signal from a coin or other target, i.e. the stability of target identification is violated on all detectors with digital target identification ( These are devices in which numbers are drawn on the screens)
What does it mean - that you can pass over a good target that will be rejected and you won't even know ( we are talking about the situation if you are in discrim mode. Or the signal from the coin grunts with a minus and shows -6, for example, if you go on all metals. you will think that a piece of iron and also pass mmo). Target Identification Improvement Mode ( the instructions call "target identification stability") uses a special filter designed for high salinity that more accurately decides what type of target is in the ground. The result is a more adequate identification of goals that you might miss as garbage, and you will accumulate more goodies at the end of the day. If the conditions for detecting are disgusting - that is, there is a lot of iron in the ground, heavy clays, etc., then it is better to use a 10x5 ellipse coil along with the "+" mode
Attention! Be aware that when "+" mode is enabled, junk targets may also be "stabilised", so in normal ground it is best not to enable this feature.
end of translation
Let me remind you that the detector was developed in Australia. And there, in the mountainous gold-bearing regions, the mineralization is such that oh. Therefore, this topic and this function are relevant there. For example, heavy clays, which are mentioned in the article, are not loam near Moscow. There are a lot of shit salts and sticks and other chemicals. And the response from this cocktail shifts in one direction or another the response from the useful target on all devices.
Actually the question is: to include or not "plus sign"?
Yes, the nearest hellish soil mineralization, similar to that described in the article, is located in the Tuapse region. But the Soviet collective farmers were industrious, they poured saltpeter on arable land with all their heart. Therefore, if you notice that ordinary targets give atypical signals (coins hit in the middle of the scale or minus), then it is probably strong mineralization that affects this, and you can turn on "+".
In my experience, this has not been the case. Here someone wrote that it happened that the ground balance went crazy. So look at the situation.
But on the other hand, be aware that physically you turn on another filter in the head of the device, which can take a weak signal from the scales lying on its side (well, for example) for garbage. and don't miss it. And you won't even know about it. So in normal life it is better not to use the function.

Uses a special filter specifically designed for high mineralisation, which makes a better decision on the type of target that is in the ground. The result of this is a more ID on targets that you may have overlooked as junk, so you will dig up a lot more keepers at the end of the day. If the ground conditions are very bad, i.e. high iron content, heavy clays etc. then it is preferable to use the 10x5" Double-D coil in conjunction with the Target ID Stabilizer.
NOTE: Be aware that with the Target ID Stability ON, variable target ID"s from some junk targets may also be stabilized, so in normal ground conditions it is preferable to operate with Target ID Stability switched OFF.

Setting up the metal detector X-Terra 74 and X-Terra 705 to search for rarities, treasures, coins.
For those too lazy to read a lot:
1.Set up the discriminator.
For coils with frequencies of 3 kHz and 7.5 kHz, the discriminator adjustment is not required. If you have an 18.75 kHz high frequency coil marked "H" in front of serial number, make the last segment of the discrimination scale 48 visible. Otherwise, the detector will cut off large copper coins. No other changes to the discriminator settings are required.
For other coils, the discriminator setting is not required.
2.Set the sensitivity level around 25-27.
3.Remove the metal detector from electrical interference.
4. Adjust the metal detector to the ground.
Now you can start searching.
