Pistol Detector - TOTeM (Complete Details)

[HaFar2010]

I see that you've managed eventually to register ok, so welcome to the forum.
At first I thought you might be a spammer who was trying to register with multiple fake email addresses, but it appears that there was some other problem.

Well done on duplicating the TOTeM project. I notice that you have modified the design somewhat, and included a DVM on the front panel. Is this something you would like to share with the forum, since this is an open-source project?

Thanks Qiaozhi.
My mail was not fake, your activation link comes with a little delay.
I called my Pd as PD-GoldZeus. It not only has DVM, but also includes some internal changes.

Hello
Dear All
Yesterday, i received a video from one of my clients.
In the video, there is an ancient hill and he is able to hunt a valuable point (buried gold).
You can see the video in https://youtu.be/UjlO-dL98BQ.

This circuit is a little messy, and who can turn it into a complete circuit diagram?

[HaFar2010]

Hello
Dear all.
Some time that several questions have engaged my mind and i haven't a clear answer for them.
So i decided to share the questions in the forum, and ask you to consult together.
the questions is as follows:

1- What is the quickest trick for producing magnetic field of gold? How long does the trick take?

2- As you know, PD has reaction than power flow, TV and low-power light.
So question that rises here is that which of them is the best test for PD?
Other words, which of the tests has most similar to gold?

3- Why does all LRL, which work base on ferrite, has reaction than low-power light?

[liudengyuand]

Cooperate type LRL, only to the alternating magnetic field has received effect, such as high voltage alternating current (ac), transformer, switch power supply, radiation, electric spark, mobile phones, etc., it is no response to constant magnetic fields, such as a huge magnet, it is induced, buried metal, it is impossible to produce alternating magnetic field, even if it is a little inherent magnetic force, but the earth's magnetic field is much bigger than it is, so is unable to detect LRL, because a huge magnet is greater than buried metal magnetic field couldn't detect tens of thousands of times, so my advice to you is, can play, don't expect too much it can give you find any metal, even if you go to waste dump, buried inside a lot of metal, it is unable to detect, video about BBS that are false, because they do not have a video for the metal, the compass effect, study a lot of people all over the world, so far, not a true feasible LRL machine, just many profiteers in hype

[abdou2014]

Is the magnetic field of a television set constant ?

[HaFar2010]

Hello
Dear all
we have done a test for detection of a freshly ring. In the text, the machine is able to detect the gold in 20 cm distance.
You can download the video from the follow link.
Please share your opinion.

Hello
Dear All.

We again received another video from PD-GoldZeus.
In the video, the operator initially detects a probably point.
After second checking, he finally digs it and gets out a buried gold.
You can see the video from following link:

The machine in the middle of the ring a few times, then take out a thing, a machine to detect, the lowest level of lies, only weak-minded people will go to the letter,

You're in a big mistake!
The first two videos have taken at different angle.
Please see it again attentively!

[liudengyuand]

I have no mistake, your video is not to respond to a metal, can't prove it to the role of the metal, dig out because you don't have the metal

It is not my video!
It has sent by my client.
Since the law of his country has restrictions on digging and detecting burid golds,
it led him to take this video at night.

[liudengyuand]

You sell the machine, so you'll only sell your machine

thank you very much for this project
I made this circuit and the circuit works very well.
this detect copper fiber 15x10 from 60cm
problem is discriminating
please help me in this case

PD can closely detect new metal. For discrimination, you must find null line. check your digital meter.
If your pd has been created correctly, number of the meter is decreased when you close it to ferrous metal (iron rejection) !

Poor naive clients.

We are seeing better promo scam videos in past as those you posted here.

After unsuccessful trying to find gold with your LRL contraption, you desperate
decided to find gold in pockets of your "clients".

At the end right approach.

Hello guys,

I couldn't find any Meter 250uA (full scale) 675 ohms here in my place... is there any other alternative to replace this meter? Can we replace it with digital meter or a 10 LED indicator. I'm not an expert on electronics but i can only follow instructions on how to build. Any help or suggestions is much appreciated.


Thank you.

Thank you.

Note that D1 limits the voltage across the "meter + R24" combination to 0.7V. Without R4, the current through the meter would be: 0.7V / 675 = 1.04mA. This is clearly too high for the 250uA meter. Hence R24 (3k) is used to limit the maximum current to: 0.7 / (3k + 675) = 190uA. The slightly lower then 250uA value stops the meter needle banging against the meter stop when a large signal is received.

All you need to do is replace R24 with a suitable value for your meter. Let's say (for example) your meter is 100uA full-scale deflection (FSD) with 1k5 resistance. A total resistance of 0.7V / 100uA = 7k. Hence, R24 needs to be 7k - 1k5 = 5k5 (or slightly higher). A simple solution would be to replace R24 with a 10k multi-turn preset, and manually adjust it to suit your particular meter.

It should also be obvious that your chosen meter needs to have an FSD of less than 1.04mA.

Thank you very much Qiaozhi. You are a great help.

please tell me ...what is the totem's circuit active passive switch ? how search ?

[abdou2014]

Active means transmit and receive, Passive means only receive .

Hi HaFar2010, I See in Video that PD of your clien Detect buried metal without moving PD from Left to Right or Right to Left , my question is with How Method works it. (Ferite+Magnet etc...or ...).

[HaFar2010]

Hello
Dear All.

According to my previous posts,
my first PD has great successes
because my clients not only sent me their successes and feedbacks
from different countries, but also they proposed me several suggestions.
After analyzing the feedback and much effort, finally my new TOTEM PD is ready!
the version has a special package and higher sensitivity to gold!
Circuit of the PD is TOTEM, but I did a small change inside it in order to getting high stability.
You can see the pd in following link:
