How Pulsed Proportional Stimulus Works:
The unique shock stimulus used by your HC-8000 system is delivered in
short, intense pulses, not a continuous shock. The pulsed stimulus gives
your dog a chance to think and avoids sending the animal into panic.
As your dog first comes within the outermost boundary area, a slow
beeping tone is sounded and a short duration shock pulse is applied at a
slow pulse rate. This first pulse is a FULL VOLTAGE stimulus but, it is of
very SHORT DURATION. It will immediately get your dog's attention but,
it is so short that your dog will probably not perceive it as painful.
If, instead of retreating, your dog continues to travel closer to the boundary,
the shock pulse RATE continues to increase along with an increasing rate
of sound pulses, until they are delivered in such rapid succession as to be
unbearable to your pet, encouraging retreat from the boundary into the
"safe haven" of your yard. The use of progressively increasing shock pulse
rate is a very humane technique because it allows your pet to decide for
itself how much stimulus is required to initiate the retreat behavior.
(Note that some competing systems use a "tone only" warning zone before
applying shock. This sounds like a good idea, but we have found it to be
ineffective. Often the dog will stand in the warning zone waiting for the
tone to stop. The tone will drain the battery and stop when the battery
runs down, letting the animal know it is now safe to escape!) The HC-
8000 is not a zone type system. We apply a short shock stimulus at the
very first correction along with the sound stimulus. This will discourage
your dog from standing in the boundary field waiting for the tone to stop.
However, because we use pulsed stimulus, the initial shock will not be
traumatic to your pet. If your dog tries to move forward, pulse rate is
immediately increased to encourage retreat behavior.
Progressive Training Tones: The use of progressively increasing sound
pulses along with the shock pulses tends to psychologically intensify the
perceived stimulus, more quickly teaching your dog that the irritating
