Coin with 2cm dia in ground 35 cm Work stable good discrimination my tarsos test videos this link http://www.savefile.com/files/1722614
best regards tanks Emekli Amca
night.....
Hi, this circuits looks very simple and components are all here in my country. So, can you tell us more about deep and discrimination?
I had surf the link below, but i dont understand turkist language. Anyway it looks that it is a very popular detector and it had made but lots of people there. Also i saw that can be arrenge to made a very simple two box.
So Please let us know more about.
Regards

hi nelson This detector reject small and big iron objects when in non ferruos (tx 150v pp)
it is very easy video are give you the information Nice machines, very suitable for us amateurs to build..

tarsos is made in turksh by emekli amca
this vlf detector is work at 15,4 khz
Tx and Rx coil diameter 18cm but setting DD coil total diametre is about 24cm
Tx coil = 136 turn + 12 turn = 148 turn
after you can test with osicilascope to coil. It should be about 130v
osc 12turn if 12V 136/12=11,33 , 11,33x12=135,96V
And Rx coils sinus Vpp:
Rx coils acord condansator 6n8
Tx coils acord condansator 10n ( there is must to 60V between the 10n's base)
and at 1&3 pin but this acord condansators must to be in coils connection pcb at coilboard
in this picture there is 1k Resistor but this is pull out after setting coil.(it is for easy setting)
but screening Tx coil with aluminium gelatine full envirions and shield to ground
setting coil:
At first turn right end 22K pot
approach toeach other coil come to dead point.This is DİSC.
if you turn the pot left -right but no sound turn oposite to 22K slowly and set the disc
you have to hear of tarsos sound
after silent to sound with disc pot and doing fine tune of sound with G.E.B
Hi DIRCEU.
I recomend you to build delta pulse, cause is a very good machine, good deep and very stable.
By now i´m buildind Gary PI, one is under construction and soon i´ll make two more units.
Gary PI had compared against Fisher 8X and the results are show on Gary´s web site.
After i finish it i ll post my results.

Hi ismail surek and thanks for helpping us to get the picture about tarsos metal detector.
Also i whant to know deep test results, so if you can help with this, will be very helpfull
After my PI proyects , i ll try tarsos, so any extra information will be very welcome.
