Simplified and effective remote dog training systems designed by Garmin using proven Tri-Tronics technology. The Delta series sets a new standard in dog training with a simple, push-button design and an easy-to-read LCD display, enabling you to correct your dog instantly, for a stronger connection between the behavior and the training. Includes a stylish, ergonomic handheld unit plus one compact dog device that are equally rugged, waterproof and reliable. It also allows you to select the correction type for stimulation, including tone and/or vibration modes, giving you options based on the situation, your training preferences, or your dog's behavior. The device offers a consistent range of 1/2 mile. The device even remembers each individual dog's training settings and can support up to 3 dogs (with purchase of additional dog devices) on one handheld unit.
