Lrl from Italy

[ford]

Thanks Franco

Can it detect buried metal pipes?

I tested it but I can't detect any thing!

I'm sure that there is very buried metal in our places

One more question about the potenciometers. Which one can be with on/off switch and which one is better to be multiturn for better results?

[FrancoItaly]

Hi ford,

Lrls can reveal gold, silver, copper and their alloys as long as they have been buried for some time and are insensitive to iron and steel. You have to have a test field where you have to bury some objects like silverware or coins at a depth of about 20 cm and wait 3/4 weeks (or more depending on the type of terrain).

Hi Kaligula,

No need for special potentiometers as On / off switch or multiturn.

Ok, but to not put additional switch I want to put potentiometer with switch. I don't know to which one is better, to 470k or 22 k?

[FrancoItaly]

I do not understand what you mean to do, the 470k / 22k ratio establishes the operational gain, what is the switch for?

For turning on the device

I do not see any picture.

I do not see any picture.

I can't upload pictures, I don't know why. So my question is to put switch for turning on and off the all unit. Its better for me to not put additional switch, I want one of the potentiometers to be with switch. Which one is better to be with switch?

Hi Kaligula,

It's not a good idea, every time you turn it on, you have to find the right setting. It is better to have a separate switch. Anyway 470K or 22K is the same thing.

Ok, thanks for answer. I purchased this pcb from this document. Does someone has made this device with this pcb?

[ford]

u4

I think Franco pcb is better.

[Napsterce]

Franco has explained that his pcb has it's own capacivity which plays role in the whole circuit...

[kaligula]

To use Franco pcb is best way with minimum risk, but nowhere here I couldn't find display stage pcb with 3 led. Because that l purchase this pcb, so we'll see the results. By the way I want to ask administrators why I can't upload.pictures.
