Recent Discovery

[Mark-VA]

Recent discovery of the conductivity switch on my White's TDI SL.
The video shows what I've found.
It also works the same with the 7 1/2" dual field coil.
Just the opposite happens if you run the machine with the conductivity switch to high, low conductors are also heard.

More information to follow......

Rotate the coin on edge and pass it over the coil. The time constant of the coin is a lot lower on edge. (My guess)Passing the coil edge flat is the same as center on edge.
