The Delta remote training device - using proven Tri-Tronics technology - sets a new standard in dog training with an easy-to-read LCD screen; intuitive, 3-button-front controller; separate side buttons for level adjustment and dog selection (train up to 3 dogs with additional dog devices). Delta can even remember an individual dog’s training settings and is optimized to work on all dog breeds and coat lengths. Simplified and Effective: Delta is ergonomically-designed to require only 1 hand to operate with 3 front “action” buttons for stimulation, tone and/or vibration. Side buttons and an easy-to-read LCD let the trainer switch easily between the training configurations and different dogs being trained. The dog device is optimized to work on all breeds and coat thicknesses and has an effective range of up to 1/2 mi. 3 Ways to Train Your Dog: Delta offers dog trainers the option of using either: continuous and momentary stimulation, vibration or tone. Or, use all 3 in 1 session. With 3 correction configurations (viewable in the LCD display), the trainer can select the training option best suited to the situation and dog temperament. Delta offers 1/2 mi range and the ability to control up to 3 dogs (with additional dog devices sold separately) and quickly change between them.
