If you're referring to TOTeM, then please look at the diagram on page 241 in association with the schematic in Fig 14-15. The passive/active switch is a double-pole changeover (DPDT) type.

That is the correct type of switch, but I cannot comment on the PCB as it's been designed by someone else.

My project for king PD
is not like your project only the box
what the problem friend of the box is equally?

you call it a fraud??!!!

but you stupid or what

on the contrary it is a free advertising for your PD

and the project is not entirely your

Hi

Look it you can find what you seek

Hello, NICOLAS, delta pulse is not hit me five meters, I did, but I would like to improve on this basis, enhance it, may I ask what do you do? Thank you for your answer

Hi you can use big frame my dear 3x3 m you can go to it deep

About your ask. I make and to repair any type of detectors

Welcom

Two ways to increase the power to detect:
1.Increased to 25 cm long ferrite
2.Increase the output power of the transmitter
What do you think?

This device made by a skeptic to prove that LRL detection doesn’twork, and you trying to do modifications to make it work, doesn’t make sense.

You cannot prove a negative.

The purpose of TOTeM is to allow experimenters to build an all-electronic LRL for themselves, do their own tests, and make up their own minds on the subject. It was also designed with the idea that experimenters should modify the circuit to meet their own requirements. The underlying concept of TOTeM is based on data that is freely available in the public domain. It provides both passive and active modes, and reacts to the usual laboratory tests in exactly the same way as certain other pistol detectors. It also works as well as any other all-electronic LRL on the market.

Skeptics often get accused of rejecting LRLs without having any personal experience, which is also one of the main reasons why TOTeM was designed, built, and tested. Many people want to build their own LRL, but have no idea where to start. That's where TOTeM comes in.

Always the Skeptics at first glance and without any experience

But there are so many who have succeeded in the LRLs manufacture of electronic devices effective. Like Andreas Morgan Nicolas and others.

Thank you for clarifying Qiaozhi

hi mosha
no.I think that is practical.I remember Esteban finds many targets.I think the plan is feasible

[Qiaozhi]

You can purchase an all-electronic LRL from a company like Mineoro, which involves parting with a large sum of money, and will definitely buy you an expensive education
OR ...
you can buy one from Mozzie_1957:
http://www.longrangelocators.com/for...ad.php?t=18932
with a cast-iron guarantee that it will never find treasure in a million years
OR ...
you can build your own.

The problem with building your own homebrew all-electronic LRL is the lack of information on where to start. You only have to examine the available information on the Alonso PD to see how sketchy the details really are. TOTeM, on the other hand, is fully documented with nothing hidden. It is the ideal platform for those who want to experiment within this gray area of metal detecting technology. Please be aware that there is absolutely no guarantee it will lead you to endless riches. It is simply a replication of the so-called pistol detector technology. It detects sparks from a great distance, as well as a CRT television - just like the Alonso PD, and those from Morgan - which (of course) does not necessarily imply that it can catch the PHENOMENON (whatever that is). However, it provides a solid basis from which to work, and in practice you can appear to be following a signal line. As I've said many times before, I have no problem with anyone wanting to experiment with all-electronic LRLs, Any experiment is a good one.

Two quotes from Thomas Edison:

1. “Negative results are just what I want. They’re just as valuable to me as positive results. I can never find the thing that does the job best until I find the ones that don’t.”

2. “To invent, you need a good imagination and a pile of junk.”

[Dell Winders]

As I've said many times before, I have no problem with anyone wanting to experiment with all-electronic LRLs, Any experiment is a good one.

Why should anyone care if you don't have a problem with people experimenting with just all-electronic LRL's? Who do you think you are? Dell

Are you worried that LRL experimenters, encouraged by this forum, may discover something you'd rather they didn't know?

Hi mustetfa

Good work for your PCB

But we like some details for your LRL. If it possible

Hi dear Mohamad look this quote from Qiaozhi you can understand that

Here's a suggestion:
On page 224 (TX Circuit) it is mentioned that R21 (10k) could be replaced with a multi-turn preset in series with a 4k7 resistor. This will allow the TX frequency to be adjusted, which will then change the sensitivity. If you do this test with a new set of batteries, and make the TX adjustment so that the meter does not have an offset away from zero, then the voltage regulator may not be required. Alternatively you could add both the regulator and the TX adjustment preset for greater flexibility.

Hi Dear Master Qiaozhi

Is that you solve the problem ? for the totem works in all countries of the world.

Maybe you're right for your setting.

I also 2 years before I encounter this problem. but I solve this problem . I found a good method to cancel the effect of the compass.

I suggested a frequency that varies between 30 to 75 kHz adjustable to calibrate LRL in any region of the world in a split second if this problem is encountered .

Dear Morgan I am with you when you go down on the earth to locate a treasure fled the frequency goes completely .
Directory you can watch here is my little video with a mobile phone by a friend during our experiences of my LRL .

https://www.youtube.com/watch?v=X7WN3NJFFdY
look here is 59KHZ and Goes 1KHZ and 0KHZ when touch Ground


https://www.youtube.com/watch?v=eqjjc6ZPS9w
But in compass rest and also increases

Note: I am against the electronic swivel but my friends think otherwise hihihih
but even as it rotates. this is a first experience for 3 years beginning

Thus a buyer of my LRL has found gold and silver together in a tomb . a near distance a bit long 600 m and a depth of 1.80 m

Dear Qiaozhi to help Goldmaxx to cancel the detection of the compass using a capacitive or resistive potentiometer to find the right frequency in his country.

I do not know his country to help . because I can define the frequency by my caluculs . and the experience of my buyers LRL . I want to thank Williams for his LRlman table definition of frequencies .

And thanks for FrancoItaly for their attention to the effect of the compass. but it must neutralize adjustment of frequency.

Waiting for your good news dear Goldmaxx

I AM WAITING YOUR ANSWER IN FORUM

Hi mohamadder

Sorry, but I have only the book “Inside the METAL DETECTOR” from Qiaozhi.
It includes all the details to build a TOTeM PD. I can only recommend this book.
I am a LRLnewbie and have learned a lot about LRL with the book from Carl and Qiaozhi.
Of course, I am experimenting further with the TOTeM.

Check out the thread from Sneshko that he could publish something from the book

Here is the link

http://www.longrangelocators.com/for...ad.php?t=18794


Hi Nicolas

I have made some small modifications to the TOTeM, but I can not test the device properly.
The problem is that I need a target (phenomenon) in order to locate it and to calibrate the device after that. I have done many tests on places, where what could be, but all without success.
I also think that, as you have already written, the problem is together with the right frequency in my country.
For this reason, I've built up from a few months ago, a small test field and buried silver coins. I hope that in a few months is build a small "phenomenon" that I can calibrate a LRL and locate it.

Now it is winter by us and I can not make any tests outdoors. But I still have some projects, that I want to build and test them in the summer.


Best regards to all
