The Delta XC remote dog training system from Garmin, with proven Tri-Tronics® technology, gives serious dog trainers more control with more simplicity. The handheld controller features intuitive, 3-button design with improved false-correction prevention (dog select lock) and easy-to-read LCD display. The compact collar/receiver features changeable contact points (long and short). Together the system gives you 18 levels of continuous stimulation and 18 levels of momentary stimulation plus tone and vibration, in 3 correction configurations, and the ability to set the device to train 1, 2 or 3 dogs from up to ½ mile away (with purchase of additional dog devices). Simple and Effective Delta XC 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 training configurations and different dogs being trained. The slim, compact dog device comes with interchangeable long and short contact points for all breeds and coat thicknesses and has an effective range of ¾ mile. Three Ways to Train Your Dog Delta XC offers dog trainers the option of using 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's temperament. Delta XC offers the ability to control up to 3 dogs (with additional dog devices sold separately) and quickly change between them. Tough, Waterproof, Long-lasting Like all Garmin outdoor products, Delta XC is designed to be effective, rugged and waterproof (IPX7) with a long lasting rechargeable, lithium-ion battery in both the transmitter and dog device.
