Lrl from Italy

It has been buried for nearly ten years. When the L-stick was popular all over the world in those years, I buried it for experimentation, but the L-stick failed and I didn’t feel its effect.

When I had the test field silver objects were buried at about 20 cm and were marked starting from about 4 m if I remember correctly. I think the depth depends on the type of soil, the mass of the metal and how long the metal is buried.

[liudengyuand]

If the depth is only 20cm, it is almost any real effect,

I did not say that 20 cm is the maximum depth, I have not tried to bury deeper.

[humhum]

For deep of this Rec system , I think that is up to 5 meter (for big metal) or more ...

Mr. Franco ... among all the equipment I have, your LRL looks like a shining diamond. Thank you.

The higher the frequency, the farther the detection distance

[Babak51]

Yes, the type of soil and the height of the area must also be considered

Yes, higher frequency and voltage identify better targets and harmonics

is it possible for you to send pcb ?

is it possible to send pcb drawing

I suggest adding a passive filter after the antenna inductance

Good day ! What cutoff frequency should the filter have?

[liudengyuand]

100M

Are you still doing

Yes, I'm doing everything. Until it is possible to locate the target. Perhaps you really need to hit at 100 MHz or close to that.

[liudengyuand]

yes

I located a great treasure with Franco lrl 3 days ago, I haven't digged yet , there is a royal tomb in this direction ,
Thank you Franco

Thank you Franco

I hope you are successful.
