Hi

I have a friend who has big farms near to the boundry of neighborhood country. Hogs come to his farms as soon as it gets dark, eat, enjoy and destroy everything they find and go to the other side of boundry where they know it is completely safe(no Hunter). because there are few hunters and there are lots of food in that area they are getting increased vey quickly. we go and hunt few of them every week (i.e. two each week) they are very strong and clever. My friend is disgusted with Them because they destroy his crop. I have studied electronics. he asked me to if it is possible to hunt them using electrical shock. Have you ever seen such devices anywhere to help me? what kind of wires do I need, with respect to their power?

any other idea is appreciated!
hunting them in that area is completely legal

BTW, I don not live in USA

ThanX
