How deep do metal detectors detect is a question that can be difficult to answer. The reason is that each device has a different level of depth. But one thing applicable for all metal detectors is increasing their detection depth.
To increase the depth of a metal detector, you can:
- sweep the coil close to the ground
- increase the sensitivity setting
- reduce the discrimination setting
- install fresh batteries
- upgrade to larger coil
These factors affect how a metal detector detects targets.

Detector Guide: How to Increase the Depth of a Metal Detector
How deep do metal detectors detect? The truth is that there is no exact number that can answer this question since these devices are so diverse and exist with many capabilities. So, there are no actual numbers that tell the depth level that a metal detector can reach.
Additionally, the size of the object to be found affects how deep metal detectors can detect. However, you can always increase the depth level of a metal detector.
Increasing the depth of your device will allow you to find old relics and objects that detectors are not too sensitive and often miss. (source)
Sweep the Metal Detector Close to the Ground
One of the most common and easiest ways to increase the depth of your metal detector is to sweep the search coil the closest to the ground possible. This tip may seem like an obvious thing to do. However, many metal detector users often lose sight of how high they are swinging their coils. The primary reason is that they pay more attention to how they swing the search coil.
Metal Detecting Tip: “Low and Slow” is a popular saying among detectorists. I’ve seen folks scan right behind someone and find coins.
But the problem is that if the search coil is too high from the ground you are searching objects from, the shallower its detection level will be. So, when using your device, you need to ensure that it is not too far from the ground.
Increase the Device’s Sensitivity Setting
The higher the sensitivity of your metal detector the more it can help you increase the device’s detection. But it is important to note that the increase in the depth level will depend on the various circumstances. These circumstances include the soil type, target type, and the object’s size.
However, a metal detector’s sensitivity is a double-edged sword. Yes, it will increase the depth level of your device. But increasing the sensitivity can also reduce your device’s ability to identify targets.
Reduce Your Device’s Discrimination Setting
Most of the time, metal detectors give wrong readings to deeply buried and desirable objects. The culprit behind it is often your device’s discrimination setting that is set too high. A high discrimination setting affects how deep do metal detectors detect.
You can reduce the device’s discrimination level to the lowest setting that you can stand for a deeper detection level. Meaning you still should hear alerts for objects detected. Once you hear deep signals, you should examine them closely before you start digging. It would be best to watch out for a jump into the desirable range while swinging the coil.
With these steps, you will find deeply buried objects, not just nails buried close to the surface.
Fresh Batteries Provides Maximum Power
If your batteries are down just 10%, you could be losing inches of detecting depth. Example: With fresh batteries my older Garrett Ace 250 can scan reliably to 12 inches.
With batteries down 1 level on the indicator I’m losing close 2 inches or more depth penetration.
Upgrade Coil Diameter
If your detector is capable of swapping out coils a bigger coil can increase depth. This does come with a trade-off. Your machine will lose some discrimination sensitivity. This may mean you dig deeper trash.
Metal Detecting Tip: If you can go metal detecting after a rain when the soil is soft, your detector will work more efficiently. The moisture will create a stronger electromagnetic field around the target. As a bonus, moist soil is way easier to dig.
How Deep Do Metal Detectors Detect: A Range Adjustment Guide for Beginners
If you are still starting to learn how to use a metal detector, you may need a guide in terms of the range adjustment. Thanks to the continuous advancement of technology, new metal detectors already come with range adjustment settings. If you know how to set these adjustments correctly, you will experience smooth and hassle-free hunting.
How deep do metal detectors detect will depend on how you adjust the settings. For this reason, it is essential that you have enough knowledge when it comes to this area.
1. Set your stock settings to low
The stock settings are likely one of the aspects of metal detecting that people often overlook. But if you are a beginner in metal detecting, the stock “turn on and go” settings can be an excellent place to start. This aspect is often set at a power of 60 to 70 percent. With such a setting so high, your metal detector will be able to discriminate out iron, foil, and other undesirable objects.
Many users turn their stock settings high and use the full power of their metal detectors to find out how deep do metal detectors detect. While that seems a good idea, using the maximum sensitivity of your device cam chatter from electromagnetic interference. Such is especially true if you live in areas with multiple cellular and wifi signals and substantial power lines.
That said, less is more in your detector’s stock settings if you are a beginner. Ideally, you only need to adjust the stock set to 7 of 10 (70 of 100). (source)
2. Pay attention to the ground balance setting
Not all metal detectors have a ground balancing setting. If you own a beginner detector, it may only allow you to use a factory preset ground balance.
But if you plan to go for an intermediate or advanced metal detector, you should never overlook the ground balance setting. Incorrectly set ground balance can lead to false signals and reduce how deep metal detectors detect.
Metal Detecting Tips for Ground Balance
- Manual Ground Balance: This allows you to adjust the ground balance setting manually for you to hear the minimum amount of ground signals
- Automatic Ground Balance: The detector itself will determine and set the best ground balance automatically. This option is more straightforward and more accurate than setting the ground balance manually.
- Tracking Ground Balance: The device constantly adjusts the Ground Balance setting as it detects targets. This setting ensures that your metal detector’s ground balance is always set correctly. (source)
3. Use a metal detector with low frequency
The frequency is one of the factors that tell how deep do metal detectors can detect. Similarly, it is the aspect that tells how well the device can detect targets.
If you have a single-frequency metal detector, it will transmit high-frequency signals. Such a type of metal detector is ideal for finding small targets.
On the other hand, a single-frequency metal detector that can transmit low frequencies will provide more depth in detecting large targets.
Furthermore, there are also detectors equipped with Pulse Induction (PI). This device has more coils than single-frequency detectors. For this reason, it can send bursts of electromagnetic waves that bounce back as they hit a target. However, you cannot tell the difference between those targets that the PI detects.
4. Utilize the notch function
As mentioned, the higher the discrimination level of a detector is, the lesser trashy signals you will detect. But apart from this option, many metal detectors have a second way of doing that — the notch setting.
A notch setting is one way of removing a category from the detector’s adjustment range.
When you utilize the discrimination setting, you have to go from left to right to eliminate trashy signals one after another. But with the notch setting, you can bypass several categories. Meaning you can select what stays in and what goes out.
For instance, you can remove various categories, such as foils, and pull tabs while leaving in the 5c category. Such is an excellent option for people who use their metal detectors to detect coins and want to leave the 5c while removing the other types such as iron and 10c. (source)

Ni vigumu kujibu swali hilo. Sababu ni kwamba kila kifaa kina kiwango tofauti cha kina. Lakini jambo moja linalofaa kwa detectors zote chuma ni kuongeza kina cha kugundua yao. Kuongeza kina cha detector chuma, unaweza: - kuondoa coil karibu na ardhi - kuongeza sensitivity kuweka - kupunguza utambuzi kuweka - kufunga betri mpya - kuboresha kwa coil kubwa. Haya David hapa mtu nyuma ya tovuti hii. "Kama unavyoona, ""Metal Detector"" ni moja ya vifaa vya kugundua chuma zaidi katika ulimwengu, na kwa hivyo, ni muhimu kujua jinsi ya kugundua chuma kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina kina." Ukweli ni kwamba hakuna idadi halisi ambayo inaweza kujibu swali hili, kwa kuwa vifaa hivi ni tofauti sana na zipo na uwezo mwingi. Kwa hiyo, hakuna idadi halisi inayoonyesha kiwango cha kina ambacho kifaa cha kugundua chuma kinaweza kufikia. Kwa kuongezea, ukubwa wa kitu kinachopatikana huathiri jinsi vifaa vya kugundua chuma vinavyoweza kugundua kina kirefu. Hata hivyo, unaweza daima kuongeza kiwango cha kina cha detector chuma. Kuongeza kina cha kifaa chako kutakuruhusu kupata vitu vya zamani na vitu ambavyo vichunguzi havina unyeti sana na mara nyingi hupoteza. Kuondoa Metal Detector Karibu na Ardhi Njia moja ya kawaida na rahisi ya kuongeza kina cha detector yako ya chuma ni kuondoa coil ya utafutaji karibu na ardhi iwezekanavyo. Huenda ncha hii ikaonekana kuwa jambo la wazi kufanya. Hata hivyo, mara nyingi watumiaji wengi wa vifaa vya kugundua chuma hupoteza fikira jinsi wanavyopiga coil zao juu. Sababu ya msingi ni kwamba wao kulipa tahadhari zaidi kwa jinsi wao swing coil utafutaji. Metal kugundua Tip: <unk>Low na polepole<unk> ni msemo maarufu miongoni mwa detectorists. Nimeona watu wakichunguza nyuma ya mtu na kupata sarafu. Lakini tatizo ni kwamba kama coil ya utafutaji ni juu sana kutoka ardhi wewe ni kutafuta vitu kutoka, shallower kiwango chake cha kugundua itakuwa. Kwa hiyo, wakati wa kutumia kifaa chako, unahitaji kuhakikisha kwamba si mbali sana na ardhi. Kuongeza kiunganishi cha kiunganishi cha kiunganishi cha kiunganishi cha kiunganishi cha kiunganishi cha kiunganishi cha kiunganishi cha kiunganishi cha kiunganishi cha kiunganishi cha kiunganishi cha kiunganishi cha kiunganishi cha kiunganishi. Lakini ni muhimu kutambua kwamba ongezeko la kiwango cha kina itategemea hali mbalimbali. Hali hizi ni pamoja na aina ya udongo, aina ya lengo, na ukubwa wa kitu. Hata hivyo, nyeti ya detector chuma ni upanga wenye makali mawili. Ndiyo, itazidisha kiwango cha kina cha kifaa chako. Lakini kuongeza unyeti pia inaweza kupunguza uwezo wa kifaa chako kutambua malengo. Kupunguza kifaa chako 'Discrimination kuweka Wakati mwingi, detectors chuma kutoa usomaji makosa kwa vitu kina kuzikwa na inataka. Mhalifu nyuma yake ni mara nyingi kifaa chako's ubaguzi kuweka ambayo ni kuweka juu sana. Msimamo wa kutofautisha sana huathiri jinsi detekta za chuma zinavyoweza kugundua kina. Unaweza kupunguza kiwango cha utambuzi wa kifaa kwa kuweka chini kwamba unaweza kusimama kwa kiwango cha kugundua kina. Maana bado unapaswa kusikia maonyo kwa ajili ya vitu kugunduliwa. Mara tu unaposikia ishara za kina kirefu, unapaswa kuzichunguza kwa ukaribu kabla ya kuanza kuchimba. Ingekuwa bora kuangalia nje kwa ajili ya kuruka katika mbalimbali ya kutamaniwa wakati swinging coil. Kwa hatua hizi, utapata vitu vilivyozikwa kwa kina, si misumari tu iliyozikwa karibu na uso. Bateria mpya hutoa nguvu ya juu: Ikiwa betri yako imeshuka kwa 10% tu, unaweza kupoteza inchi ya kugundua kina. Kwa mfano, kwa kutumia betri mpya, Garrett Ace 250 yangu ya zamani inaweza kuchunguza kwa uaminifu hadi inchi 12. Kwa betri chini ya kiwango cha 1 kwenye kiashiria mimi kupoteza karibu inchi 2 au zaidi ya kupenya kina. Kuboresha Coil Kipenyo Kama detector yako ni uwezo wa kubadilishana nje coils coil kubwa inaweza kuongeza kina. Hii inakuja na biashara-off. Mashine yako itapoteza baadhi ya utambuzi wa kutofautisha. Hilo laweza kumaanisha kwamba utachimba-chimba takataka zaidi. Kwa mfano, ikiwa unaweza kugundua chuma baada ya mvua wakati udongo ni laini, detector yako itafanya kazi vizuri zaidi. Unyevu utaunda uwanja wenye nguvu zaidi wa sumaku-umeme kuzunguka shabaha. Kwa kuongezea, ni rahisi zaidi kuchimba udongo wenye unyevunyevu. Jinsi Deep Metal Detectors kugundua: Mwongozo Range Adjustment kwa ajili ya Kompyuta Kama wewe ni bado kuanza kujifunza jinsi ya kutumia chuma detector, unaweza haja ya mwongozo katika suala la mbalimbali marekebisho. Shukrani kwa maendeleo ya kuendelea ya teknolojia, detectors mpya chuma tayari kuja na mipangilio ya marekebisho ya mbalimbali. Ikiwa unajua jinsi ya kuweka marekebisho haya kwa usahihi, utapata uwindaji laini na usio na matatizo. Jinsi detector za chuma zinavyoweza kugundua kina kinachohusiana na jinsi unavyofanya marekebisho. Kwa sababu hii, ni muhimu kwamba una ujuzi wa kutosha linapokuja suala la eneo hili. 1. Uwe na mtazamo wa kweli Kuweka hisa yako kwa chini Hisa hisa ni uwezekano wa moja ya mambo ya chuma kugundua kwamba watu mara nyingi kupuuza. Lakini kama wewe ni mwanzoni katika chuma kugundua, hisa <unk>kuwasha na kwenda<unk> mipangilio inaweza kuwa mahali bora ya kuanza. Kwa kawaida, sehemu hii huwekwa kwa nguvu ya asilimia 60 hadi 70. Kwa kuweka kiwango cha juu, kifaa chako cha kugundua chuma kitaweza kutambua chuma, karatasi, na vitu vingine visivyotakiwa. Watumiaji wengi huongeza kiwango cha kugundua chuma na kutumia nguvu kamili ya vifaa vyao vya kugundua chuma ili kujua kina cha kugundua chuma. Kwa hivyo, ikiwa unafikiria kuwa ni bora kutumia kamera yako ya kamera, unaweza kuepuka kuingiliana na kuingiliana na umeme. Hii ni kweli hasa kama unaishi katika maeneo na ishara nyingi za simu za mkononi na wifi na mistari kubwa ya umeme. Hiyo alisema, chini ni zaidi katika kuweka hisa detector yako kama wewe ni mwanzoni. Kwa mfano, unaweza kuweka hisa yako kwenye kiwango cha 7 kwa 10 (kwa 100). (chanzo) 2. Kumbuka kuweka usawa wa ardhi Si detector zote za chuma zina kuweka usawa wa ardhi. Kama wewe kumiliki detector mwanzoni, inaweza tu kuruhusu wewe kutumia kiwanda preset ardhi usawa. Kama wewe ni kuangalia kwa ajili ya upimaji wa chuma ya kati au ya juu, unapaswa kuzingatia kuweka usawa wa ardhi. Kuweka vibaya usawa wa ardhi inaweza kusababisha ishara bandia na kupunguza jinsi detector chuma kina kugundua. Metal Detection Tips for Ground Balance - Manual Ground Balance: Hii inaruhusu wewe kurekebisha ground balance setting manually kwa ajili ya wewe kusikia kiwango cha chini cha ishara ardhi - Automatic Ground Balance: Detector yenyewe itatambua na kuweka bora ardhi usawa moja kwa moja. Chaguo hili ni moja kwa moja zaidi na sahihi zaidi kuliko kuweka usawa wa ardhi manually. - Ufuatiliaji Ground Balance: Kifaa mara kwa mara adjusts Ground Balance kuweka kama inagundua malengo. Utaratibu huu inahakikisha kwamba chuma detector yako ya ardhi usawa ni daima kuweka kwa usahihi. (chanzo) 3. Kwa mfano, kwa sababu ya kiwango cha chini cha mzunguko, ni muhimu kujua jinsi kina cha chuma kinavyoweza kuonekana. Vivyo hivyo, ni kipengele ambacho huonyesha jinsi kifaa hicho kinavyoweza kugundua malengo. Ikiwa una detector ya chuma ya mzunguko mmoja, itatuma ishara za mzunguko wa juu. Aina hiyo ya kifaa cha kugundua chuma ni bora kwa ajili ya kutafuta vitu vidogo. Kwa upande mwingine, detector ya chuma ya mzunguko mmoja ambayo inaweza kutuma mzunguko wa chini itatoa kina zaidi katika kugundua malengo makubwa. Zaidi ya hayo, kuna pia detectors vifaa na Pulse Induction (PI). Kifaa hiki kina coils zaidi kuliko detectors single-frequency. Kwa sababu hiyo, inaweza kutuma mawimbi ya umeme ambayo hurudi nyuma yanapogonga shabaha. Hata hivyo, huwezi kujua tofauti kati ya malengo hayo ambayo PI hugundua. 4. Uwe na uhakika Kutumia notch kazi Kama ilivyoelezwa, juu ya usawa ngazi ya detector ni, chini trashy ishara utagundua. Lakini mbali na chaguo hili, detectors nyingi chuma na njia ya pili ya kufanya hivyo <unk> notch kuweka. kuweka notch ni njia moja ya kuondoa jamii kutoka detector ya marekebisho ya mbalimbali. Unapotumia kuweka ubaguzi, lazima uende kutoka kushoto kwenda kulia ili kuondoa ishara za taka moja baada ya nyingine. Lakini kwa kuweka notch, unaweza kuepuka makundi kadhaa. Maana unaweza kuchagua nini inabaki katika na nini huenda nje. Kwa mfano, unaweza kuondoa makundi mbalimbali, kama vile foils, na kuvuta tabs wakati kuondoka katika jamii 5c. Hii ni chaguo bora kwa watu ambao hutumia vifaa vya kugundua chuma kugundua sarafu na wanataka kuacha 5c wakati wa kuondoa aina nyingine kama vile chuma na 10c.
