The DogTek EF-4000 is an underground pet containment system which enables you to contain one or more dogs in a specified area. Give your pet complete freedom within a perimeter defined by you without the need for an ugly and expensive above ground fence.
An unlimited number of receiver collars can be used with one DogTek system, so you can contain as many dogs as you wish safely in the same area. The DogTek 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 2.5 acres or 1350 feet) 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 your dog approaches the perimeter wire.
When your 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 receives small static impulses. As he leaves the area the impulses stop. After a few days, as the dog learns the boundary the impulses can be reduced and the collar used to emit audible beeps only.
