HOW IT WORKS

 This invisible type of pet fencing has been around since 1973. Many changes have been made in the industry since then, but the entire premise of how they function has stayed the same.

A wire gets buried in the ground 1-3" deep. The fence wire gets buried where you, the customer, wants the dog to be contained in. 

That wire is hooked up to a transmitter, usually located in the garage or the basement. 

The transmitter sends a signal with a certain frequency that the collar the dog is wearing picks up and turns on when the pet gets too close to the wire. The dog first hears an audible beeping alerting them that they are getting too close to the fence. If they continue, the collar delivers a correction shock. 

The correction strength is set by the customer with a push of a button located on the collar. The correction begins with tone only and increases in strength with each push of the button.
