For gun dog owners concerned about applying an electrical impulse to any sensitive canine, Unleashed Technology has designed an e-collar in which vibration is the major form of stimulation used as a cue for obedience to learned behavior. Each of three models (GT I, II and III) uses remotely activated vibration to supplement and replace an electrical impulse as a way of making any dog's training experience more positive.
