Portable Electric Bear Fences For Any Adventure

Copy of 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.

The Bear Sentry (low impedance) energizer stores 1.8 Joules and releases at least 1.0 Joule when discharged. That’s twice the minimum. That’s deterrence.
