Forget about the Sota magnetic Pulser it's a useless device.
They are using this fascinating technology of electromagnetic fields to impress people but it's useless against parasites worms like Ascaris or tapeworm.
Start by buying a Terminator 2, this zapper does not kill all Ascaris stages contrary to what is advertised on their website, but at least it will help to kill some larveas in the body and to stun the adult ones in the intestines.
I have done a mod to the terminator 2 in order to attach it to an elastic belt. In this way i can forget about it and i can wear it 24h/24h, the electrodes are always on the skin. That helped me a lot.
