With the SportDOG® WetlandHunter® 425, you can work your dog. You can get wet. You can stay hidden. And you'll definitely bag some birds. Field-tested, proven system gives you an effective tool to control your dogs and reinforce commands from 500 yards away. Adjustable static stimulation levels let you tailor the stimulation to match your dog's temperament, eliminating the risk of over-correction. The remote transmitter's dial lets you instantly select one of 7 levels of static stimulation in medium or high ranges. Or use the buttons to deliver your choice of momentary (nick) or continuous stimulation. You can also train with vibration (buzz) or tone (beep). With proper training, your dog will quickly learn to associate each signal with your command.
