Is Hidden Fence similar to Electric Fence?

No, an electric fence runs a current along a metallic string next to a fence. This string needs to be isolated from the fence. If it is touched, the current will run to ground through the individual creating the connection.

A Hidden Fence emits a coded digital FM Radio signal that features SafeLink ®. It is safe for other animals or children to touch. The stimulation comes from the posts on the receiver collar and only when it is within the radio signal.
