1.0 Joule (output) Energizer

The defining feature of an electric fence system is the energy rating of its energizer. The amount of energy or Joules that can be stored is important; how many Joules the energizer can actually deliver is critical, because that’s the shock.

Research shows that a shock of at least 0.5 Joules is needed to turn away a curious bear, but size really does matter when you're dealing with a motivated, hungry predator. Think big, bad Grizzly.
