Camp Bear Fence Recommendation?

[GodSpeed1]

Hello,
Just wondering if any of you fellas might have a preferred bear fence that you use around your camp in grizz country? Or maybe you could share an experience you may have from using this gear in the backcountry?
Thank you!!

Build your own. The pre made ones are a bit low on zap. You also MUST do an everyother hot ground wire set up. Unless you camp in a swamp.

Do a search on here and there are several threads discussing.
