Kube 4000 (110v AC Plug-in) Energizer - 2.3 Joules, Wide-Impedance

Had an issue with our neighbors dogs (aggressive, not confined, and coming after my children) and wanted to insure that they’d stay out of our property, and away from my own dogs. It only took one shock to keep the neighbors dogs away. Thank goodness!Also seems to keep out all our other potential problem animals. And our dogs have a lot of respect for these fences.

I love love love this charger. I bought it as a kit through Premiere1, with the ground rod, tester, and long insulated power wire. This charger has made all the difference for keeping cows in who don't want to stay put. We've had electric fences in the past, but the cows just didn't respect them and would push right through if they got hungry or bored. The old chargers didn't work in the summer at all, the cows didn't even seem to notice the shock. This charger has worked even:- when the ground was dry in summer-when attractive food/cows were directly on the other side-it was literally grounded out by a stray wire. Tester read at 1-2k, down from 4-6k but still working to zap cows.-at long distance from the charger, nearly a mile away-to shock poorly grounded poultry and keep them from testing the gaps in their electric netting fence-as a two strand electric temporary fence, and also as a single strand added to a permanent barbed wire fence. Greatly reduces upkeep on permanent fences to keep the cows from pushing on them.-when kept outside (upright, per instructions) year-round, in rain and snow.This charger is fantastic, and has been a very worthwhile investment for us. Electric fence always required too much upkeep before and now it actually WORKS, without cows grounding it out every week. It's immensely satisfying to have cows learn with one good shock to not put pressure on the fence again. We currently have two and I'd like to get a third.
