An unlimited number of receiver collars can be used with one perimeter wire so you can contain as many dogs as you wish safely in the same area. The EF-4000 is adaptable to all types of terrain: open, wooded, hilly, fenced or unfenced.

How does it work?
A discrete perimeter wire (up to 450 yards) is placed on the ground, buried or raised on an existing fence. This wire carries a signal from a small transmitter unit. The dog wears a discrete receiver collar that receives a signal when he approaches the perimeter wire.

When you dog first approaches the wire he enters the warning zone and is warned by a beep from the collar. As he gets closer to the wire he enters the correction zone and is corrected by small electrical impulses. As he leaves the area the impulses stop. After a few days, as the dog learns the boundary the electrical impulses can be reduced and the collar used to emit sound beeps only.
