thanks very much brodhy aft, friendly embrace for you

how is C23 2,2micro or 22nano Farad

[sevar12]

soon i bild coil and if work i post pcb in last find many mistake

Well any good news?? Did you build detector?

C23 is 2,2uF, not nano Farad. You can use 1uF on pcb and 1uF below pcb.

this is what i do but no coil i try with another but its stabil only 5 sec but C23 i make 22n i will try with 2,2uF

hi mesy64
you want build tr metal detector good
http://www.geotech1.com/forums/showt...locator&page=8 this is better way but i recomond you delta pluse is much more stable highly sensitivity xr71...............rajesh

[sevar12]

i try to make a Pulse star - G some what you say fore him ?

[mikiaj]

Sevar12, can you tell me did Sacho TR REV 1.3.rar worth or not?
Too many circuit I do not know what to do

Thanks

mikiaj , sorry friend but now i don't have time to final this , i must bild a coil fore him


sorry fore bad english

Ok my friend It will be ok if you send me circuit and pcb without mistakes
and coil when you finish.. maybe I can try to build coil
Thanks for your fast answer.

Hi I am MFC, Messy64 and rajesh you can trace the PBC if you have the schematics of the circuit, only you need the schematics, if you don't have the printed board you can trace it based in the electronic schematics carefully, I had built the Gary Pulse 2 project with the original PBC and I draw my propper printed board and it work perfectly.

Ahhh important, you must know the coils parametter for make any detector.

Good Luck

Hi I am Maikel MFC the XR71 is a Pulse Induction type Detector and the Two Box are Transmit Receive detector, they are two differents types of the metal detectors, the stability can be good in both machines, it's most depend of the stability circuit in the source of the detector and the design in general.

For two Box use a stable power source for get stability in the rest of the circuitry (thermal stability and oscillators too). Look, the sensibity is a relative parametter because too many factors affect it.. example the type of coil, the inductance, inpedance, the zise of the metal object to find and the diametter of the coil for it, the mineralization of the ground etc.

Hi Sasho
I will like to try this summer your TR detector, so for that i need your help to build it, by sharing schematics and pcb.
Also, can you tell me if you are the person that have for sale a TR locator shows on http://www.youtube.com/watch?v=2Lu_ZvKN9IM ?

Regards

how many coils contains TX and RX and what
thickness to the conductor of TR locator
