greeting !!!

thanks friend
but i want to make this coil
http://www.geotech1.com/forums/showt...mplete-Details

(i saw in clip of #1761 diffrent this coils and i think this is working better , any idea)

hi please say me this guru
i want make DD coil and need help about Diameter and RADIUS of that.
for the picture (thinks it is DD coils ) and say me of the wires
many thanks

You can draw it on a paper and squeeze a coil into such shape by hands. Circumference is estimated by similarity to an ellipse, and there you have it. Unless you want to make a machine that produces coils to some strict dimensions, it is very OK to do it approximately.

Dear Mohandes, your English translator (Program?) makes for very bad English. If I may try to correct it for you, I would offer the following translation:-
"Imam Ali alayhis says :- If everyone teaches me a new word, I will remain enthralled."

hi,

is it possible to use a DD coil from a Tesoro Cibola with the IDX-Pro?

Thanks!

i have not data about your coil
please COMPARISON inductance and resistor your coil whit this coil
look page1 please

ok,thanks dear Davor
i need to APPARATUS to COUNT number of winding , do you have it or link or ...

There are many examples on youtube. For example this one: http://www.youtube.com/watch?v=fPc9NIH_o5o

No, you do it primary school way ... یک، دو، سه
(1,2,3 ...)
Later on you check inductance to see if you did well. + or - 10% is unbelievably good accuracy.

Hi,

unfortunately, the inductance and resistance do not match (0.94mH TX and 15.5 RX for the Cibola Coil). Would it be possible to create a little adaptor PCB between the connector and the main PCB that compensates the inductance and resistance with additional L,C,R components on the PCB?

I used an old Casio calculator and hard wired the = button to a separate micro switch
type in "1++" then every press of the micro switch adds 1 to the total.
Modern pound shop calculators would be hard to do this to as they don't have proper copper tracks. Some sort a carbon screen printed tracks?

hi i think it is so easier for you to make a new DD coil
sorry me my english not well

[mohandes]

hi anyone know about the max depth can detect under the ground?
my friend davor say 1or2meter and i think it can not the max depth for idx.
regards

[golfnut]

I know some people have a mare making this unit.

Hope this drawing helps.
