Pi VLF combo

[chub]

Does such a machine exist? I see the new nokta impact reviews says 36 machines in one. Perhaps a little marketing spin but the choice of 3 frequencies is certainly appealing. While there are a number of multi frequency vlf machines available has anyone ever made a PI VLF combo machine to switch between modes (and possibly swap a coil?)
Thanks

Whites has a patent filed for such a machine, but nobody has produced such a hybrid unit yet...at least as far as the public is aware.

So it would seem in the future Whites would be the company to watch.

I once made a deal with the devil, and agreed to design a hybrid VLF/PI. It was a combination of the MXT and SurfPI, but I never got round to building it.
