Pistol detector

[wubian]

Hi all

I want to build a really useful and practical PD(long range detector), can any body help me to find the right place for building it?

Regards

Why not simply at your home?

Hi dear WM6,

oh its for my poor english when I said "right place" I want to say "which thread" or "topic" is good for building.

I am sorry again, its for my poor English,

so could you please help me to find a really good and useful PD for building? If I have to pay to buy documentation its ok. I am just need a good and useful PD.

With the best wishes for you

Hi dear wubian,

I hope our friend Geo would say: the more complete schematic to build PD you can find in book "Inside the metal detector" available to buy here on forum.

See Chapter 14 - The TOTeM Project

Oh WM6, I think you are Geo sorry I'm confused... you are a kind man,

you point to a PD device on that book called "TOTEM" right?

between TOTEM and mineoro schematic that already posted on this forum, which one is better and more useful?

thank you WM6,

[wubian]

Greeting Qiaozhi,

could you please tell me more about TOTEM? is it right to compare it with mineoro? I want to know which one is better?

Regards

thank you WM6,

TOTEM is more documented in details, so I would suggest you TOTEM.

Sure the TOTeM is more simple to build,and maybe better than the PD. I told many times the PD project is very complicated,and most of people who finish this project said no good results as LRL.
TOTem is the right choice,buy the book and start the construction.

Hi every body

First I want to say: Dear Qiaozhi thank you for all your help and support. so finally I gonna build a TOTeM! and I will post my pics here as soon as possible.

but still have one question and hope somebody could clear me: how meters are consider as medium or long distance?

If this device can detect gold and etc on maximum 50 meters, I want to say its perfect for my purpose. so 50 meters distance is short, medium or long distance?

Regards

It is very, very, very long distance, you never achieved in a whole life. No matter of LRL you use.

But I support your persistent work and admire your great enthusiasm.

Short range refers to the detection distances achievable with standard metal detectors. Medium distances are in meters (probably under 100m), and long distances can be in kilometers (depending on what whopping lies the manufacturer thinks they can get away with). Obviously there will be some overlap between these definitions.

Perhaps others would like to comment...

This circuit can help you

hi Reza vir
it has built the circuit and it works;
a photograph of the building because I want to build the circuit. if you wanna say a few words about the construction ... thanks

hi reza vir
this circuit is ultrasonic sensor But can be used with little change as lrl.

hi
and what this change?

[nelson]

My friend this is just an ultrasound detector for measuring noices that comes around 40 Khz. So it will not work has an LRL

ok
i agree with you nelson
but Changes can be used.

hi mustefa
Please complete the circuit changes its mind and let
