Re: two zappers at once

The 30kHz mini zapper is a well made zapper and is well protected on its output circuits.
Orgonite Africa has a lot more of hand work involved, and I cannot say much about it.

Both being powered by battery, there is little interaction in their simultaneous use.
If they had been used on very close locations, path of current could have make interference one with each other (without harming the output circuits). This was not the case.
Resistance between both locations (skin and body impedance) makes them practically “isolated” one from the other.

It seems to me you had a failure of your Orgonite Africa Zapper on a confusing moment of your session.
Please, consult Orgonite Africa for advice or other particular checks before sending them your zapper, if still under warranty.
