We all have seen many videos comparing  metal detectors , changing the coils, frequencies and all kind of settings so they can maximize the capabilities of the "machines"! 

But what about the same machines abilities to detect larger targets like a 20x20 cm or 40x30cm  on greater depths?? 

Am in the only one Qurious about it 🤪 

 Have someone seen something about it??

What are you searching for that is of such a size?  Most people (looking for smaller items, like coins or natural gold) would prefer those large targets gave minimal response as they 'polute' the area around them causing masking and thus missed good targets.  Well, we can wish all we want but it's not happening, thanks to mother nature (aka physics -- the universal rules).

People who are interested in large, deep targets use either two-box induction balance (IB) detectors or the pulse induction (PI) detectors with the strongest pulse currents.  I assume the videos you refer to are comparing IB/VLF detectors -- deep large target recovery not being their strong suit.

Large items are generally easier to detect to great depths so we don't usually spend a lot of time discussion the detection of the larger objects.    

We tend to focus on small item detection because those are the hardest to detect and most affected by masking and ground minerals.

We tend to call large object hunting, "cache" hunting and and most any good detector with a larger coil will detect those target sizes deeper than you would want to dig by yourself. 

I'll just throw this out there.....holes deeper than your waist are unsafe to dig alone.  You need a buddy for deep hole digging.   And real excavation requires some forethought before you hop down in there...even bulldozer scrapes....you need a buddy.

Hello!! 

Well to be honest ,it s not like I am looking for something. I recently start engaging with this exciting hobby!! 

You could say that I just wanna know about the different capabilities of different detectors etc....

Something bigger could be an ammunition box or a just any box sized object !! 

I also came across with some of Garrett's detectors....like  Gti 2500 or ATX deep seeker or  ATmax!!They claim to go deeper for" larger" objects as well for  smaller coin size!! 

Ps: thanks for mentioning the PI and IB detectors

Hello Mike!! 

Thank you for the addition info!! 

Well I bet they do, but also sounds  REALLY interesting don't you think?!?! To dig something out as deep as your hight.... It's crazy!!!

First off, if by 'they' you mean the Garrett advertising creators, you need to take that (along with any other company's advertising) with a grain of salt.  Deeper than what?

The GTI-2500 has a two-box attachment, so that fits in with my earlier post.  The ATX is a ground balancing PI so also fits my earlier post.  I don't know if it has a high current pulse as the Minelab GPX's, but pretty sure it beats some of the GBPI competition such as the no longer manufactured White's TDI/SL.  As far as the ATmax, I think they are getting into more hype-advertising than solid evidence would support.  Is it a good IB/VLF?  Yes.  Is it deeper than its competition?  Many would argue 'no'.

Hi ,

Most of the metal targets , perhaps 99,9% of them , are small/medium sized targets , this is the reason why experienced users do not bother with the 0,1% big sized targets , because the probability to find one is very low.

Considering the depth , do not expect more than 20inches for a 20x20 cm or 40x30cm ammunition box when using  a single coil vlf detector like an Equinox , Vanquish , Garrett , Deus etc ... With a PI like a Minelab GPX you will go deeper but you loose the iron discrimination , and apart from the GPX price , you might find not very funny to dig on a tin can at 30inches deep ... 🙂

From top class detectors  and 11"-13" coil .. you can realistically detect a larger coin at 40 cm, a military buckle at 65 cm, a field bottle at 90 cm, and a military helmet at 120  and more cm ...

-------------------------------------------------------------------------------------

450 grams of silver depot can be detected at 85-90 cm ...my Tek.G2 in Test...

--------------------------------------------------------------------------------

The NATO 20x 30cm ammunition box with the Two-box can be detected 150 cm in the ground.

That's interesting!! Nice videos , thanks 😁 

Never had in mind the Teknetics 😬

      This is a topic relevant to every(?) form of detecting -- ground coverage.  I'll list several questions concerns I've had but any replies of course aren't limited to these, nor do they need to address  any of them.  Just tossing out some ideas to prompt further discussion.
      1) What methods and efforts do you apply to ensure full ground coverage in the cases where that is one of your goals?
      2) Is your sweep a straight line path or an arc?
      3) How long is your sweep?
      4) How much do you overlap consecutive sweeps in the direction you walk?
      5) How much do you overlap side-to-side swings when following parallel paths (e.g. when walking two side-by-side swaths in the same direction how much does the left end of one path overlap the right end of the next path or vice-versa)?
      6) Have you ever measured your coverage?  How well do detectors with GPS (e.g. Minelab GPZ-7000 and Minelab CTX-3030) monitor ground coverage to this detail?  Have you used other devices to measure ground coverage.  E.g. I can imagine a drone with camera could provide useful data.  Are there smartphones app that would help quantify coverage?

      Just dreaming...
      What'dya think? Minelab technology going on the next moon mission?
      X6 must be space-worthy.

      If this question has been addressed elsewhere, I apologize in advance and hope someone can give me a link for it.  I have noticed that other companies besides Minelab are coming out with PI detectors for less than $3K.  How do these detectors compare to the best Minelab detectors for Gold and also relic hunting?

      On the Anfibio Multi (and I think Kruzer & others) there is a definite step in sensitivity between 39&40 Gain and again between 69&70 Gain. Is this a change in the Internal Threshold? In a way this would be the inverse of the way the F75 adjusts sensitivity according to Mike Hillis.  Regardless, it is a very good set up in difficult sites. Most NM users know about the difference in response speed between 89 & 90 Gain on 3DI. This is different. I had read about these steps in a forum post that quoted Alper of NM. I can't seem to find that post now that I want to re read it.

      This is the most out of this world Minelab detector patent I've ever read. There is so much here, some very sci-fi like, I don't even know where to start. My takeaway is they seem to be positioning themselves for a drone based detector eventually (main details in this patent could be easily transferred to a drone based platform - IMU, GPS, magnetometer, heads up display, FPV, remote control, robotic/vehicle mount, etc) . That is 100% a guess. But in the meantime, there is some interesting, novel items in the pipeline that we might actually see on a machine in closer future?
      No clue if this is a coin machine or gold machine or if it's something they are actually working on right now or just trying to get control patents on such things for the future which may or may not arrive. One thing is for certain, Minelab is BUSY in the engineering department. A few of the highlights:
      Heads up display over glasses/head mounted display (aka augmented reality). Settings, target visualization, shading of detected/not detected areas (I asked for this specifically 5 or 6 years ago here, awesome to see it in a patent now). Plus a camera showing the coil (why would you need that if not operating remotely as from a drone?) The detector has a camera, IMU (accelerometer) and magnetometer to determine position with accuracy. The IMU tracks the position of the coil in real time in relation to both the ground and the target, and combined with the camera video feed will provide a "visual" of the target in the ground through the glasses/head display, as in form of a heat map which increases accuracy with each pass of a coil over the target. A GPS tracks the machine position to properly map the IMU/coil visual target data on the ground and let's a user see the mapping as they detect. This data is recorded for future historical use and can be shared.  Centimeter accuracy with the visual target heat mapping. Potential operators/users include entities other than humans such as "robots" and "an AI (artificial intelligence) using a metal detector" and this line: "The metal detector may be handheld, mounted on a robotic arm of a vehicle or a robot."  Wireless connectivity to computers and phones, transfer of files containing settings configurations from instructors or expert users Remote control of the metal detector through apps on laptops or phones Ability to upload maps, including detecting data, historic human activity, buildings, or other items that seem to indicate custom mapping capability Internet connectivity, potential control through the internet (again, why if not for a drone type device?) "Teamspeak" to other detecting members in the area wirelessly Visual/spatial discrimination Accurate depth measurement Synthesized audio mode, eliminating noise completely and allowing the detector to "recreate" a synthetic audio stream based on data from prior swings Delayed audio processing (enhanced audio) mode or real time audio mode, ability to seperate multiple close targets, reason for this I venture a guess why below ---> This patent actually seems to be describing a completely new method of RX in a detector. Which is actually similar in some ways to the wacky idea I had years ago of reducing EMI/ground noise by emulating a radio telescope array. But in this case they appear to be describing a fairly ingenuous method of doing something similar with only one coil by monitoring RX of the same target at different points in the swing (with the IMU tracking these points) and combining all those RX signals. In this way (and this is my guess, the patent doesn't explain this), you can form a sort of comparator, gradiometer, or interferometer to seperate the wheat from the chaff, so to speak. If that's what they are doing, then I find it to be brilliant. If not, then I just gave them one hell of an idea to patent for the future. 
      That probably sounds like jibberish to non-engineers. But I want people to understand the brilliance in simple terms. Consider this: EMI is random. At any given point in your swing you'll get noise here, but not there. So if you compare two points in the same swing, you will hear noise one point but not the other point because the "zap" already ended. But you might hear a good target at both points in the swing since it's not random like EMI, it's always there in the ground. So, you can effectively eliminate EMI by comparing what signal is not there at two very close points in the swing, and keep the target since it's always there.
      Similarly, with ground, the ground changes as the alluvium changes since soil is inhomogeneous. But a target is still the target. So, a similar method can be applied to the ground.
      In theory, you could use ideas like this to essentially get rid of the Difficult type timings and keep your gains boosted high, and deal with EMI/ground in this way instead which does not require reducing sensitivity. A totally new, novel approach to RX in a metal detector. The audio processing is very slightly delayed because they are using that time to compare measurements at a few different coil positions before letting the audio processor signal that there is a target present. That's my guess. If that isn't what they are doing, then someone else should patent that and thank me for it later when Minelab buys it. Either way, they have something totally new in the RX department here. And the future of detecting looks bright and interesting to me still.

      Hello, now here’s an opener that might just get me banned on my first post!
      Bear with me, my intentions are pure :)
      Does anyone know if it would be possible to jam an MD signal? The reason I ask is to combat the evident problem we have in the UK with “nighthawks”, illegal detectorists.
      Over here, any landowner can grant permission for detecting on their land (with caveats, known historic sites are protected by law). What often happens is that such a permission is granted and a detectorist innocently sets about his / her business. Someone less scrupulous spots this person and assumes there may be something important there, so shows up at night with a couple of friends and the landowner awakens to a field / lawn full of holes, then bans metal detecting.
      Historic sites are also looted.
      Just an off the wall question, how tricky would it be to build a device to block this on a piece of land? Anyone any ideas?
