he only use bronze coins...

maybe he's still in the bronze age there!

Hi Geo
Excuses me, in my post #43 I referred to your instrument at 135 Khz with a receive coil, with a gain of 1000 it's necessary to balanced the receive coil, or the receive coil it is made vwith few turns.

Best Regards

Hi FrancoItaly.
Sorry i made mistake.....about detectors.
But and this detector is a mono Rx coil and also i have another coil to stimulate the Rx coil. Today i changed coils... i made a square 15cm coil with shield. It seems more sensitive... these days when stop to rain i will go to test it..

[detectoman]

hey estaban, my questions, 1: have this new design build whit only rx the same capacibilites of one lrl ; tx-rx or 2 is whit less power, 3what is range?4 need you very hig power steps of amplification and bateries, and excess of complex complement for control, or is normal stable? what features, what advanteges, what discrimination? 5 is innecesary tx for one good lrl
is good deep capabilites? how many trasistors
in advance thanks

Dr. Best beat that hands-down: already got half-a-mile over a coin!

You guys better change your mind and start build Dr. Best device... it's worth!

Hi Max.

The Dr.Best device will give us much money. Sorry... i don't like so much money, so for me it is good the Estebans LRL

MFD

Dear Geo
I 'm looking for a Good MFD.I saw u have a good one!
It is very good that u test it.
Can u send Schematic,PCB and part list for it pls?
Thnak u and Good Luck

Horizons? All detectors are affected by magnetic field of Earth. When you have adjusted excluding it, well the difference is another cause, almost always metal buried many years. Of course, you can use a kind of dish connected to - , but you must found distance between dish and coil.

I modificate the old I have, but now with preamp. Look shielded cables in input, potentiometer and main PCB input. Also you can try shielding the core or the coil, deppend what you use. I use core and aluminum loop.

You can use a kind of dish connected to ( - )....

Kostas.... u answer after 12 years???

Kostas.... u answer after 12 years???

Noooo, I'm just 12 years more mature..). something is going on..absorption...maybe the perfect lrl is a simple sensitive receiver that tracks a movement from an existing energy field in front of the receiver.
