A completely new and effective boundary training system called Pulsed Proportional Stimulus. A far more effective and humane method of delivering shock stimulus, it trains your pet more quickly with less discomfort and our HC-7000 Series was the first
to use it. Pulsed Proportional Stimulus Technology: Applies shock in very short, quickly pulsating, bursts. As your pet moves closer to the boundary wire, the delivery rate of these bursts is continuously increased until your pet decides to retreat. Although
the initial shock will definitely get your petâ€™s attention, it's too quick to produce any noticeable pain. However, if your pet continues on an approach toward the boundary wire, the shock pulses are continuously increased, becoming more intense as the distance
to the boundary wire decreases, until even the toughest, most stubborn animal decides to retreat.
