IMPI SPC-100 Automatic Dog Bark Control Training Collar With Shock Correction Mode for Small to Xlarge Dogs

A sophisticated, patented and reliable electronic bark collar which is undoubtedly the best value on the market. The IMPI BARK utilizes static pulse correction to stop your dog's barking.
Some dogs respond to a sonic or ultrasonic stimulus; some to vibration; some to a spray stimulus (e.g. citronella, lemon etc).
Almost all dogs respond to a static pulse correction and stop barking. This is why an electronic bark collar utilizing static pulse correction is widely regarded as the best solution for nuisance barking.
How IMPI BARK Stops Dogs Barking

The vibration which occurs in the dog's throat when barking, triggers the piezzo quartz sensor within the bark collar to emit a static pulse correction through the EzyFit contacts.
The correction starts with 2 low level 'reminder' corrections - a combination of ultrasound and a very low level of static pulse correction - and increases through a further 5 levels, should the dog persist in barking.
The dog will soon associate the 2 reminder corrections with its barking and realize that the way to avoid the further unwelcome correction, is to stop barking. With 7 levels of correction automatically increasing in intensity the dog is empowered to properly set the appropriate correction setting to motivate them to stop barking.
