The simple, straightforward Garmin PRO 70 allows intuitive 1-hand training and control with a range of 1 mile, so you don't have to take your eyes off your dog. A top-mounted selection dial provides for 6 levels of stimulation for adjustability without complexity. Pro 70 can expand to train up to 6 dogs (additional dog devices required) and features remote-operated LED beacon lights on the dog device for low light conditions and built in Bark Limiter, activated on the dog device, for a quieter kennel.
