The Minelab X-Terra 705 is the flagship in the Minelab x-Terra series. The updated version of the X-Terra 74 metal detector has a number of major technical improvements confirming its focus on advanced, experienced users. Some buttons have a dual purpose so that the operator can work with many functions while the metal detector control panel remains easy to read and intuitive.

Minelab X-Terra 705

The Minelab X-Terra 705 has all the features of the X-Terra 305 and 505 and new ones have been added that make this metal detector an excellent full-featured tool for all search conditions and purposes. The X-Terra 705 metal detector has the ability to manually (from 0 to 90) and automatic adjustment from the ground (the balance of the ground), there is a well-established mode “Beach”. In addition, it is possible to constantly track and redeem the impact of ground changes. This allows you to search sites that metal detectors could not cope with before. This feature copes with hot stones and when switching from wet to dry sand, this new feature of the Minelab X-Terra 705 metal detector has already proved its advantage in gold tests. Setting a negative value (from -15 to 0) increases the depth of search and the ability to detect very small targets. If the value is set in the range of 0 to 15, the reliability of the identification of the target is significantly improved and false signals are nulled.

Minelab x-terra 705 Features

The new Minelab X-Terra 705 metal detector has a display light. The Pin Point function (detection of the exact location of the object) has been significantly expanded. The new metal detector allows you to determine not only the center of the object, but also with high accuracy shows the boundaries of the object by manual calibration of the pin-point. The X-Terra 705 has 4 built-in search (discrimination) programs that can be customized and stored. IronMask has been added. Separately, the AM button (All Metal) is able to quickly move to All Metals mode. The scale of metal type segments consists of 28 segments (from -8 to 48 in crevices 2), 4 segments per black metal and 24 segments for non-ferrous metals. Sensitivity has a range of 0 to 30. There is a function of the sensitivity threshold (from -5 to 25). To determine the type of metal by sound, the metal detector allows you to set 1-2-3-4 tones or multi-ton (28 tones).

Excerpt from minelab X-Terra 705 field test:

“Working with minelab x-terra 705 is a pleasure! I was especially pleased with the ability to clearly and clearly define the goal. It begins to seem that it is you and not the device able to see through the ground and find targets. On the wet salt sand it was possible to work at the sensitivity of 28, as a result we found several coins that previously missed other devices. The high-frequency elliptical coil proved to be particularly good in the “knocked out” places.”.

MINELAB X-TERRA 705 is equipped with internal voltage control function

The task of the seeker in the field was and remains to control the level of battery charging. Very often search engines forget about this important indicator, and the result of such negligence is either disabling the device at the most crucial moment, or reducing the depth of detection of targets, caused by a drop in working voltage. On Minelab X-Terra 705, you do not face such trouble - x-Terra 705 is equipped with an internal voltage adjustment scheme, so metal detectors maintain this parameter at the proper level until the batteries are completely discharged. Thus, whether the indicator is half full or indicates a minimum battery charge - the detection depth on the X-Terra 705 does not decrease. Still, it is recommended to always have a spare set of batteries - always come in handy. By the way, about the readings of the indicator of the level of charging - the most reliable they become only after a few minutes, so it is worth a little wait, and only then to assess the level of charging of batteries.

MINELAB X-TERRA 705 is equipped with NOISE CANCEL noise suppression feature

The next factor to be noticed immediately after the metal detector is the presence of power lines and other electrical interference lines directly on or near the site under the survey site. other metal detectors, cell phones, etc. When dealing with permanent electromagnetic interference on minelab X-Terra 705, it is recommended that you use the Noise Cancel jamming feature, which has both manual and automatic settings.

Volume adjustment on MINELAB X-TERRA 705

When searching with Minelab X-Terra 705, it is recommended to use headphones. When searching with headphones, the volume control of the signal, of course, does not matter, but if the device is not connected without the headphone connection, minelab X-Terra 705 offers the search engine a range of volume ranging from zero to zero thirty-pieces.


A separate analysis deserves such an important search feature as the level of threshold tone - “Treshold.” The ability to accurately expose the value of threshold noise is an important factor in the work of the metal detector, which is by no means deserving of neglect. Forgetting about this option, and even more so to take its presence for granted, it is impossible, because its parameters depend on the quality of the received response. These settings in Minelab X-Terra 705 devices have values ranging from -5 to 25, and when working with old coins and relics, I do not recommend using negative values - the best option would be to set up on the earshot. A fairly high volume causes the treasure hunter to ignore small and deep-lying targets, giving a weak signal, due to a large number of false positives. Similarly, ignoring small and deeply lying objects occurs when searching in silence - their weak signal does not reach the level of the established threshold tone. Negative values in the threshold tone settings on the Minelab X-terra 705 are appropriate when searching on the beach, near the shore, where the soil is mostly wet sand, and the search area has a fairly high level of pollution from the objects of strongly oxidized iron and foil. But in this case, there is a high probability to miss small gold targets with a fairly significant depth of laying. In general, you should always remember that the x-Terra 705 threshold is the starting point for audio feedback, and the search performance depends on its installation.

How to make a metal detector at home

The X-TERRA 705’s depth and stability dependence on SENSIVITY

Another important feature of minelab X-Terra 705 is “Sensitivity” or “Sensitivity” - it directly depends on the depth of detection and stability of the device when searching on soils with varying degrees of mineralization and littering. Minelab X-Terra 705 has a sensitivity range of 1 to 30.

The wider the range of sensitivity settings, the more accurately you can customize the device to perform a task. If a large area with rarely occurring targets is selected to search, the sensitivity level can be set at maximum values without the risk of receiving a mass of false positives and phantom signals. However, the high level of sensitivity on the Minelab X-Terra 705 significantly reduces the depth of detection that in areas with high mineralization soil, covered with a large amount of man-made debris threatens to receive negative results Search.

Once the sensitivity is adjusted, you should carefully adjust the ground. The X-Terra 705 has a balance range of 0 to 90.

MINELAB X-TERRA 705 lets you automatically tune into the ground

In addition to these parameters, minelab X-Terra 705 has the ability to automatically adjust to the ground, which allows you to search in the mode of constant monitoring of the soil with the compensation of interference in automatic mode, which is very important when working on the areas with high levels of soil mineralization, such as on sea beaches.

How to adjust the ground balance to MINELAB X-TERRA 705 manually

The balancing of the ground in manual mode on the X-Terra 705 is as follows: by activating the balancing button, several times swipe the coil up and down until the characteristic beep. An important point is that whatever the balancing regime is, make sure that the coil does not touch the ground. When the coil moves from top to bottom, the beep will noticeably change the tone. When receiving a low-tone signal, combined with the unacceptably low balancing options displayed on the display, you should adjust the settings by pressing the plus sign button because it is executed in this case Incorrectly. The opposite is that getting too high a signal on minelab X-Terra 705 indicates an actual level of soil mineralization exceeding the exposed values. Adjustment of inflated indicators is made by pressing a button with the image of the sign minus. Adjustment of the ground balance should continue until the smallest toss of vibrations are obtained when the coil moves vertically.

Set up an automatic ground balance on MINELAB X-TERRA 705

The Minelab X-Terra 705 has a “GB” button to balance the ground, which activates the Auto GB automatic customization function. Balancing should be done by pressing the “GB” button and holding the coil up and down. The display will appear “AU” and after a few seconds Minelab X-Terra 705 will independently debug from ground interference using metal detector software settings. Each balancing change should take all of the above step-by-step, and constant optimization of ground-leveling in automatic balancing mode can be your most useful habit, because otherwise you risk loss of depth of object detection. Minelab X-Terra 705 allows the device to continuously control the balance. All of the above does not mean that you have to adjust the balance all the time, but sometimes doubts about the correctness of the settings are so great that you can do the balancing several times, and sometimes it gives positive results. Manual balancing on the Minelab X-Terra 705 is somewhat unfinished, and requires more time to get optimal settings. To put it figuratively, the balance of the ground is like a discriminator, and what happens when the discriminator settings are incorrectly exposed, you know.

In light of the above, the “Tracking Ground Balance Offset” or “Ground Balancing Adjustment” feature, regardless of the settings, is deeply sympathetic. This feature is equipped with a metal detector Minelab X-Terra 705, and I appreciate the ability to work in the mode of automatic setting of the balance of the ground, while adjusting the necessary parameters manually without changing the mode with automatic Manual. Very comfortable! The range of settings includes two segments: positive with values from one to fifteen, and negative - from minus one to minus fifteen. There was a discussion about the feasibility of using the “Tracking Ground Balance Offset” function in the negative segment and the results of similar experiments. My firm belief is that the most preferable option would be to use the settings in a positive segment, as they allow you to adjust more subtly to the ground.

Discrimination settings on MINELAB X-TERRA 705

The next point of our review is, of course, discrimination. It should be configured after all of the above settings have been set, and we will now look more closely at the choice of search mode with the connection of this feature. It should be given credit to the manufacturer - all models of the X-Terra family give the opportunity to start the search with the help of built-in programs, just pressed the button - and started work. However, in addition to pre-installations, the device allows you to choose which objects to pay attention to and which should simply be ignored. If you’re still a novice in the search business, use built-in software, gradually moving on to manual discriminating settings.

Learn more about the X-Terra family’s discriminations. Each model is equipped with a discriminator with a different number of segments:

1. Minelab X-Terra 34 and 305 are twelve segments of four VDI resistance indexes.

2. Minelab X-Terra 54 - eighteen segments of three VDI resistance indexes.

3. Minelab X-Terra 505 - nineteen segments of three VDI resistance indexes.

4. Minelab X-Terra 70 and 705 are twenty-eight segments of two VDI resistance indexes.

Each segment of discrimination corresponds to the range of object resistance indicators corresponding to black or non-ferrous metals. Negative values of VDI resistance indexes refer to the target as objects made of black metal, positive Values of VDI are typical for objects of colored metal. If you notice, there is a tendency to reduce the number of resistance indices and increase the number of segments of discrimination depending on the seniority of the models of metal detectors. This gradation allows the most accurate identification of found objects, the ideal combination is certainly one indicator of resistance per segment of discrimination, implemented in such search devices as White’s Spectra DFX and White’s XLT, where the parameters of discrimination are 95 in negative and 95 in positive sectors.

MINELAB X-TERRA 705 and tone tuning

The next step in setting up is to select the number of tones of sound responses. The Minelab X-Terra 305 offers the option of choosing one, two, three tones, or a multi-ton response mode. Minelab X-Terra 505 and 705 models added a chthreeton response to the standard set. Obviously, the difference between different members of the same family in the field of sound settings is minimal.

From one tone to polyphony

Choosing one tone involves receiving a signal of one tonality, a two-tone mode divides the targets by sound into two tones, and so on. The polyphonic mode gives each segment discrimination its own sound, allowing you to identify the object without addressing the display metrics. Many search engines still have a similar sound response with the information displayed on the display. I personally prefer to listen to the detector, choosing to work polyphonic mode with the function of searching all metals.

The next topic worthy of attention is pinPoint precise detection mode, which is part of the mandatory feature set of each of the X-Terra models. The mode is activated by pressing the PinPoint button, after which the device goes into static search mode with VCO audio and graphic display of information on the display. Immediately after receiving the targeting signal, press the PinPoint button and hold a criss-cross over the object. The display displays a circular scale showing the center of the object. It should be noted that this technique is applicable to monocride.


application of the DD coil requires a little more effort - here you should pay close attention to the movement throughout the circumference of the coil, from its beginning to the end. From your own practice: the response from the object will be located just above the center of the coil itself.

Determining the size of the find

In addition to the standard PinPoint feature, the Minelab X-Terra 705 also has a “Sizing Mode” feature. This option allows you to determine the value of the object without changing the sensitivity settings and not risking to get into overload.

By the way, the above model is also equipped with a backlight display, which greatly facilitates the search in low light.


The ability to change the working frequency by changing coils, inherent in all metal detectors of the X-Terra line, today is not unique, but to forget about this feature of this family is not worth it. Recall: Minelab X-Terra 34 used only 7.5 kHz, Minelab X-Terra 54 - frequency 7.5 or 18.75 kHz, Minelab X-Terra 70 - 3, 7.5 or 18.75 kHz. The new generation of the X-Terra family already uses multiple frequencies at the same time without changing coils - Minelab X-Terra 305 uses frequencies of 7.5 and 18.75 kHz, and representatives of the older generation of the family - X-Terra 505 and 705 - all three frequencies.


At the moment Minelab is producing eight types of coils for self-produced metal detectors: concentric six-inch mono-roller 7.5 kHz, concentric nine-inch mono-rollers 3, 7.5 and 18.75 kHz, concentric The six-inch DD coil is 18.75 kHz, the concentric ten and a half inch DD coil is 7.5 and 18.75 kHz and the elliptical ten-inch DD coil is 18.75 kHz. All coils have protection from moisture, but to work at a depth above one meter is still not recommended. Very well work in shallow water concentric nine-inch monorolls of any frequency.

Features of working with small coils on X-TERRA 705

I would like to remind you of the sensitivity of small-diameter coils to small objects and high-frequency coils to objects with low conductivity, corresponding to the conductivity of gold, and low-frequency coils to objects with a high conductivity index, corresponding to silver and copper. Concentric monocrates give a greater depth of detection than similar in the form of DD coils, but this property is shown only on neutral soils. DD coils provide greater stability and efficiency in areas with highly mineralized soils, and generally better share goals. From personal experience: on the site it is necessary to search first mono-roller, then repeat the route with the Coil DD, and once again for fidelity to walk the mono-roller. If there is anything at all in this place, the finds are guaranteed in each passage. My undisputed favorite is the nine-inch 7.5 kHz monoroll, then the DD, and of course I always have a low-frequency mono at 3 kHz, because the temptation to find silver and copper is always great.

To search for gold

Of the nine-inch concentric coils, the 18.75 kHz coil is the most sensitive to the ground, and I have had to lower my sensitivity from time to time to ensure greater stability. This type of coils is optimal for the search for small objects made of gold, but sometimes the segment of finds gets and aluminum.

Eliptic coil for MINELAB X-TERRA 705

The elliptical DD reel left a double impression. It is optimally suited for beach search and work in study mode, but I am not a supporter of beach search, so this kind of coil did not impress me.

To search on a large area

Concentric ten and a half inches of DD coils are ideal for those who prefer to explore the most voluminous areas in a short time - guarantee stability and excellent depth.

Search for coins and fine gold

To search for coins is preferable to a reel 7.5 kHz, the same who prefers to look for small objects of gold, I recommend using the coil 18.75 kHz.

MINELAB X-TERRA 705 on littered areas

For littered areas, the best choice will be six-inch monocrates, but on such sites it is also worth using the DD coil 18.75, which has an increased sensitivity to small targets.

Thus, to conduct a full comprehensive search, each treasure hunter must have a set of sufficient set of coils of different properties.

MINELAB X-TERRA 705 search technology

Now it is worth directly moving to search technology. As mentioned above, I prefer to work in a polyphonic mode of searching for all metals, when receiving a response and deciding to retrieve an object confirming the decision by holding a criss-cross coil, comparing VDI readings and response. If they remain unchanged - the object is definitely worth digging, if the VDI index is constantly changing, there is a possibility that the object consists of a highly oxidized black gland. This is the advantage of polyphony - you can immediately determine the significance of the goal. So, coins and buttons give a stable, smooth, but sometimes quiet signal. Large-form oxidized iron gives a very stable and clear response and VDI in a positive sector. If you receive a questionable response, you should reduce the speed and work with a cross-cross coil. If the signal was broken, the target is quite controversial. However, I recommend digging anyway.

Feedback from the x-TERRA 705

It is also worth paying attention to how exactly the response from the object occurs. Receiving a mixed signal with a VDI index that is questionable, we can conclude that under the coil are two different objects, one of which has some value, and the second is insignificant. In this case, when the coil is held in one direction, you receive a signal about a high VDI, and when conducting in the opposite direction - about low. Sometimes it can help to hold a reel criss-cross, but usually such goals I classify as hard-to-identify, and extract them without much thought.

Object position

Also on the VDI index has a significant impact on the position of the object relative to the coil - at the flat position you get one indicator, standing on the edge of a coin or a button will give a different from the first index. In this case, it is worth carrying out rotational movements of the coil with the lowest angle of deviation from the surface of the earth, paying close attention to the VDI readings. Of course, if you do not have the proper search skills, then you should work out a kind of library of responses to certain purposes. It is very useful to test the metal detector in the air - study the response of the device to a variety of objects in different planes relative to the coil. These exercises will quickly find common ground with any search engine, and to the first practice session in the woods or on the field you will start already fully armed.

Discrimination segments on MINELAB X-TERRA 705

As mentioned earlier, each X-Terra metal detector has an individual set of discrimination segments that correspond to a specific range of VDI resistance indexes. Compare:

1. Minelab X-Terra 34 and 305 - from -4 to 44

2. Minelab X-Terra 54 - from -9 to 45

3. Minelab X-Terra 505 - from -9 to 48

4. Minelab X-Terra 74 and 705 - from -8 to 48.

Of course, the expansion of the VDI range receives full approval, but it is worth paying attention to the following factor: the presence of different ranges indicates a difference in the reaction of the device to a given target. I received practical confirmation from Minelab X-Terra 54, 74 and 705 on-air testing. A highly oxidized small nail was used as a test object.

The name of the metal detector VDI Index

Minelab X-Terra 54 -9

Minelab X-Terra 74 -8; 46

Minelab X-Terra 705 -8; 46

With a simple comparison, it is easy to conclude that the X-Terra 54 and 505 devices will have lower performance when responding to a black iron object than other devices in this family.

Discrimination work on X-TERRA 705

Work in discrimination mode is approved with one amendment - in rough settings of the discriminator can be observed a decrease in the depth of detection, and, accordingly, a decrease in response from the object. This feature is inherent in metal detectors with processor processing of the signal. I prefer to work without discrimination, because it is the search for all metals that makes it possible to fully assess all incoming signals, even if they are quite contradictory.

Features of high-frequency coils for X-TERRA 705

Another important point: high-frequency coils give a large number of phantom signals. This happens due to the ability of high frequencies to expand the range of resistance indicators of low-conducting objects (gold) and narrow the range of resistance indicators of high-conducting objects (silver, copper). So sometimes it’s not superfluous to turn off the z48.
