ALso Ian , in that last coil the tx and rx are all encased in the one casing? roughly what sort of separation is there between the 2 coils?

On a side note, i may have missed it , but what machine are you running this on?

Looks good , reckon you'll be testing in no time!

sorry for the twenty questions....

thanks for that Ian ,
I think the later tx coil is the one with the "round" Windings ?

will have a new bt v4.1, speaker in my hands this week to do some testing with, you can order in the hundreds if required, will put up a link if they work ok, just under 10aud. 

A man is stumbling through the woods ,totally drunk,when he comes,upon a preacher baptizing people in the river.
He proceeds into the water,subsequently bumping into the preacher.The preacher turns around and is almost overcome by the smell of alcohol,where upon,he asks the drunk "Are you ready to find Jesus?"
The drunk shouts "Yes i am!"
So the preacher grabs him in the water.He pulls him back and asks"brother, have you found Jesus?"
The drunk replies "No ,I haven't found Jesus.
The preacher shocked at the answer,dunks him in again but for a little longer.He pulls him out of the water and asks "Have you found Jesus,brother?"
The drunk answers "No , I haven't found Jesus!"
By this time the preacher is at his wits end and dunks the drunk again- but this time holds him down for about 30 seconds and when he begins kicking  his arms and legs about,he pulls him up.
The preacher again asks the drunk "For the love of God ,have you found Jesus?!"
The drunk staggers upright,wipes his eye,coughs up a bit of water, catches his breath and says to the preacher"Are you sure this is where he fell in?"

Thank Ian

You are correct 1" apart.

Regards, Ian.

Hi Ian,

I’m assuming that the ohms measurement is performed with the probes one inch apart or do you use the four probe sensing method.

Hi AuTich,

The product I am using is Ex one of the coil makers and now no longer available to me what you require is something with a resistance of around 60 to 100 ohms per inch if you find something let me know as I am looking for something as I have only enough left for one coil that stuff would be OK for painting on the inside of the coil housing if the resistance is OK and it is a simple way of shielding anything with solvents is a problem on Styrofoam and XPS former's.

Regards, Ian.

Thanks Ian,
