The iQ Plus e-collar has training modes in Nick, Constant, and our patented Pager Vibration, much like the vibrate feature on cell phones. The iQ Plus outputs a low-mid stimulation output from 0-100 levels, using our patented front facing Rheostat Dial for gradual and precise control. A 400-yard range provides consistent communication with a waterproof receiver/collar. The iQ Plus is the tool that many professionals trust when shaping basic obedience in companion dogs.
