Hi everyone!

Has anyone tried to make a very large DD coil (or a set of interconnected TR-IB coils) capable of sweeping a vehicle 2m wide and if so, what effect? Wink

Best regard

  LOL, Sorry I was thinking you wanted to detect a Car or truck. 

I'm assuming that's a PI set up.  A VLF coil that size would have some serious EMI issues I would think.

EMI is not the only problem to solve, I think. Wink
I would like to use Whites DFX with such an experimental large DD coil to search for stone meteorites. PI detector without discrimination is probably not suitable for this.

Lot's easier going with PI I would think.    Well Calculated out the Required Coil winding's.

Never hear of a coil of that size for a VLF machine.
you can get a 12 inch coil for the DFX

I have DeTech Ultimate 13" DD coil.
Well, It remains an experiment. It may turn out that problems with EMI, tuning the coil(s), stability, mechanical stiffness of construction and others can not be solved.
Preliminary assumptions I have.
