Portable Electric Bear Fences For Any Adventure

Painful but safe

That clicking you hear is the sound of energy being discharged along the fence wire, and it’s a safety feature.

The flow of electricity is regulated by the energizer (also called a charger). It stores electrons in a “capacitor” and then releases them in a “pulse”; after each pulse the capacitor stores up electrons for the next pulse.

Clicking indicates pulses being released by the second. However, each pulse lasts a tiny fraction of a second.

Pulsing allows a bear to break contact from the fence once it has taken a shock i.e the connection will last but for a split second so the bear’s muscles won’t lock up and make him “stick” to the fence for a continuous shock. The bear will be able to run away, shaken and deterred, not harmed.

This is a good design feature for you too in case you touch a hot wire by accident (or metal while you’re using the voltage tester)!

So when you hear a clicking sound like a metronome, that’s your Bear Sentry operating normally, and safely. 
(If you hear something else or in addition, like a popping, fizzing or crackling noise, there might be something wrong: go check your set up for a short (see the FAQ “How do I know if the fence is working properly?”)
