The SportDOG Brand SportTrainer 875 is designed for field training and hunting with close-working dogs. Featuring an easy-to-read OLED screen, you can view the selected dog, static stimulation level, and mode, as well as battery status, with just a glance. This, combined with large plus/minus buttons to easily toggle among dogs and stim levels, makes the SD-875 especially suited for multi-dog hunting situations. With SportDOG Add-A-Dog Collar Receivers, the remote trainer can be expanded to control up to 3 dogs at once. 10 levels of both continuous and momentary 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.
