Product UsageFence host by pulse booster module grounding of 12 v voltage booster to high-strength pulse voltage 12000 v, and connect the transmission to the metal wire mesh, when animals near the fence and contact the conductive wire, high voltage pulse will give animals a strong sense of high voltage electric shock,but the pulse duration is very short (0.2 seconds) so it will only get in contact with animal a stern warning. It doesn't harm the animal. After a few warnings, the animal is conditioned to stop touching the enclosure and move around inside it.
