Serbian "Most Wanted"

I understand thank you all for your help but this unit does not only two t-ferrous metals and general metali.Vse it is beautiful for yourself si.Blagodarya all again for helping.

The actual depth of this type of detectors in the ground about 15 sm.Tova is because working with three signals, hear is one.Ground make invisible problems. Depht in air is not actual. Good variant for beach search. The best variant is with two signals.|Magnum or R-C motion filter|
My congratulation to Ivconic.

Thanks a lot to look this cable with this section

ivconic. problev I mizhte video and tell me please where is the reason. 28 DD.TX-75 0.21mm.RX-160 0.21mm. TX-470nf.

Phase "ran" away, so it seems!
And i know why is that; your TX coil is not good.
For Tx you should use 0.45mm - 0.5mm wire and achieve ~1mH inductance.

Hello detector works but I have a problem I have a feeling that many sensitive when touching the antenna and cable detector started screaming.

Looks like you reversed coil pins!?

Only I put them on the front panel. Others how to adjust.

[ivconic]

Disc and Sens.

[emoxristov]

Here's my card. Which potentiometers to put on the front panel.

Yes....Thanks a lot.........Freddy
and I want part list of this pcb http://www.geotech1.com/forums/attac...5&d=1352457719
......... please ......

A friend made the SMW with the original SEF 12x10 coil for Teknetics T2. There is not extra wire for coil shield. I think that at prototype (T2) the shielding is connected at the half tap of the Tx coil. But here at this project we can't ground the half tap of Tx coil. So how we can connect the coil shield???
Also with this coil he can't take signal from oscillator more than 15V p-p.

Regards

The shielding of the coil is connected directly to the RX coil inside the plate.

I have not done the coil SMW. I've used an original Teknetics T2 coil. SEF 12X10.

Can you tell us what the results with ( Teknetics T2 coil )

€ 1 coin more than 47 cm in air.
