Magnum on steroids!

Good, do you have an oscilloscope? with that it's easy. If you dont have try to adjust some how the frequency of the Tx coil so you get good phase angle between Tx and Rx. The oscillator drives the Disc and Geb sample circuits. Did you checked your components isnt there something wrong?

Instruments are there, collected more than one metal detector. TX +220 nf 12.3 kH, RX is nonresonant. I will experiment more ..

Coil

Can somebody show me pot and switch connection's for TH version? I have some confusion's, i have original coil for gm and got only ferrous target's.

Can somebody show me pot and switch connection's for TH version? I have some confusion's, i have original coil for gm and got only ferrous target's.

I had same problem when i conect pin 2 from coil on 47nf gm got just ferrous target, if i dont conect pin 2 gm works but on everithing geb and disk doesnt work correctly
there is picture how i conect coil
P.S.
coil is original detech sef 30x25cm for gm and works on 8 and 18khz[IMG][/IMG]

Is this scheme correct?
And whether someone has done this pcb ? Is there any mistake?

[MARKORAM94]

i fix detection for ferrous and no ferrous metal. I will show on picture now, but i dont have diskrimination coil is conected very well but i think something is wrong with this pcb or some conection is wrong

Markoram on my pcb is connected, I'm not done yet so I can not tell you what and how it works.

something mising i try a lot variant to fix but something was wrong

[crni1]

My PCB still stands because I do not have the correct scheme.

i think this is corect schematic
but i cant garanted because my pcb doesnt work i was chek pcb with this schematic and everything is corect done with schematic
but i think something misig there

Been looking on the md4u.ru site.

Seems some are having a lot of success using this with a small coil in amongst the iron and picking out tiny gold and silver.

link ?

schema correct, pcb correct, no smt only tmt. post all here rusian forum. thanks. lobofoma best gold seeds nugets roma sexterous. anderwater also best.

best steel wire coil rx.tx. phase-tx. steel wire max.magnetica field. best deep. check wire compas. effect see noddle. big deppt steel wire windings. check self, big troth compass.

Sincerely nothing special !

Vlaser wrote over on MD4U.RU

"It's time to try out the mask 4. Was pleasantly surprised when using the device began picking out a coin for a coin on the trash. The DD coil is slightly larger than the open palm

.

Deus, Fisher 75 and safaris are blinded in this place. Worked black-colored as a machine gun. Very sensitive to detail, does not miss. Very satisfied with the device.

Looking at his signature vlaser has built more than a dozen machines and likes this a lot

Unfortunately I can't find which board version that he made
