Pistol detector

[WM6]

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?

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.

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?

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...

Thank you Dear Qiaozhi, you spent a lots of time to answer my questions till now. I am a expert vbulletin manager and can help you if needed.

With the best wishes for you

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

This circuit can help you

[demis]

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

This circuit can help you

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
