THE ELUSVE 1us TC TARGET

[Tinkerer]

To be able to detect a target with a TC of 1us (one microsecond time constant), with a PI detector, we need to take a very early first sample.
A TC of 1us means that after 5us the eddy currents are gone.
With a delay of 3us we should have a chance to still detect the 1us target.

I have found on detectorprospector.com website and in some YouTube videos the inside of a Minelab Commander coil.
It seems they use two plates (upper and bottom), appears to be two sheets of some paper coated with some kind of graphite ).
Does anyone here has some experience with this kind...

Hello Forum,

I have some general questions regarding PI coils and construction.

1) Mono Coil
The mono coil is lying flat on the floor. How should be the winding direction of a mono coil in respect to the ground (the floor)? Clockwise or counter clockwise?

if we use Litz wire to build 18" mono coil for Minipulse what would be the results any body explain ?

Hi!

Let's try to demystify coil making by sharing our coil data (coil size, wire diameter, shielding material, inductance, resistance, frequencies, peak voltage, phase information). I'll start by posting data on 11" tesoro widescan DD and
adequately performing homemade 14"...

Mu metal is a special type of material that essentially blocks magnetic fields. I've been wondering of taking a 1/2 inch wide piece long enough to wrap around the circumference of a coil, and gluing it to the edge of the coil, would provide shielding that would allow you to work up close to steel...

Anyone here know what coils will work with this unit, I'm lookin at pickin up a blue max 950 deepscan 9-1/2" coil, will it work with the classic II ?

Thanks for any help or replies in advance..
