tr metal detector

[mesy64]

hi to all
i need to tr metal detector for larg target in high deep (3 meter )
any one help me please .guide me and give schematic.
tank you

hello mesy64: in the panel on sasho varna, where you is going, are the schematic of tr, but whitout pcb, too exist other tr for chemelec, in anterior post, here are pcb, want chemelec autories, you need want, here have you details necesary for make your two boxes, too sevzirfo two box, charles rakes two box, only one little of experimentations and voila!
you should want in the treadhs, not impatiente, two box is only, one trasmisor oscilator and one sensitive receptor, in the two case, put, two square coils, but 3 metros of depth, is not easy, may be 2 mt, on medium piece, whot big radiance metallic of contaminatiom, one embrace

i see sevzirfo detector.i guste that detect deep is verey low .i interesting that build varna .becuse told sascho that detector can detect one target 15cm*15cm in 1meter .this is very good.ok?
please help me about varna .i need to pcb.
or you can give me a plane that seem varna
tank you my freind

dear esteban very tanks for guide
one question esteban
how mach detect maximom this tr detector for metal ????example 50*50cm???
you can help me for build this circuit????and coils???
150dpi is better or 300dpi????
tank you

You can read in text that is capable for to detect an iron object of ball-size at 2 or more meters, depending of time buried.

150 dpi and 300 dpi is the resolution (or quality) of the text in pdf format.

one question:
sensivity tr detector is diffrent between gold target and iron target????
for exampel this detector detect target ball saiz iron in 2meter ok.this detector can detect a gold target ball saiz in 2 meter or down meter???
your belive this detector can what detec a target gold 50*50cm ?????
please guide me for coils?

Don't ask esteban, he has never made working detector in his life.

[detectoman]

esteban is great in make of all class of detectors, i have photos of detectors he made, he has very years of build everyvary circuit, in special case of fiber glass, the project of esteban are inventional , modifications, expanditions, he give in thunting big amount of material one on everything

[mesy64]

Don't ask esteban, he has never made working detector in his life.

esteban in big teacher in build detector.he know very and you have principle detector.
my opinion is you have not any about detector and you can build a only toy car or tpy detector

esteban is teacher for users

Is possible to build a 2 boxes for ferrous and not ferrous metal, audio is the same, but 0 central microammeter show you at left indication for ferrous and at right for non-ferrous. The same for 2 boxes can be used as walkthrough security MD.

Of course, 50X50 cm is a big target, this is not problem for a 2 boxes in not very mineralized ground.

For to be good operative, you need separates power supply: a lot of batteries for TX and other for RX, this mean independent batteries.

The coils are explained in the text.
