The SportDOG Brand® SportTrainer 1275 gives you long distance control of your dog and features an easy-to-read OLED screen that clearly displays the selected dog, static stimulation level, and mode, as well as battery status. Large plus/minus buttons make toggling among dogs and changing stimulation levels a breeze, making the SD-1275 especially suited for multi-dog hunting situations. With SportDOG® Add-A-Dog® Collar Receivers, the remote trainer can be expanded to control up to 6 dogs at once. 10 levels of static stimulation, as well as vibration and tone options in select modes, allow you to customize this system to fit any situation or dog’s temperament.
