I am currently playing around with this idea for improving depth and efficiency of metal detectors i have built one for my 60khz diablo and shows promise the idea would probably work for pulse induction designs as well
this idea is just something i came across in my other interest free energy devices.
and is very simple for VLF - two transmit coils phase connected the same way stacked one on the other is supposed to amplify the magnetic field and there is no reason you can not stack 3 or 4 for the same effect something worth experimenting with.
this is a patent explaining it.

and a little trick i use to balance my coils is null as close to what you need then use a small ferrite fragment moved around to do the final tuning point then glue it down works for me.

conspiracy theory is the JFK magic bullet covers all contingency that go against the system even turns corners and comes back
and airplane fuel can melt steel buildings that stuff must be over unity where
