Garmin's Sport PRO offers a simple and intuitive way to train your sporting dogs! It features a compact and ergonomic design, and a quick turn dial allows you to switch between 10 stimulation levels as well as auxiliary functions. This configuration allows you to use the Sport PRO one-handed, so you never have to take your eyes off your dogs. In addition, the Sport PRO can link up with 3 dogs (dog devices sold separately), and is impact and water resistant.
