This is the patent issued to the application which was on this site a while back. The invention is a method which reduces the current required from the battery. What is most interesting is that Candy provides a simple explanation in the write up as to how Minelab Pi's work.

Thanks Dave.
I never had opportunity to work with Minelab Pi, connect him to osciloscope, and see wath really happen.

Is any similarity between multyfrequency-Vlf ground treatment, and Candy ground treatment ?

Is any balance between tx energy of long pulse and addition of short pulses. If is so, is Minelab Pi have eny regulation voltage of long puls, dependence of ground conditions?

Quite hardly for me, to deal with patent language style.

Sory for bad eanglish.

Salute,
