Garmin’s PRO 70 Dog Training Bundle offers a simple and straightforward method of training your sporting dogs. When linked with the included PT 5 dog device, the PRO 70 provides 6 levels of continuous stimulation that can be increased for optimized effectiveness, as well as an audible tone setting. The PT 5 dog device also has a built in LED beacon which is remotely operated to help locate your dogs in low light environments. The PRO 70 handheld can connect to up to 6 dog collars, allowing you to train multiple dogs at once (additional dog devices sold separately), and the simple one-handed operation ensures you never have to take your eyes off your dogs. In addition, the PRO 70 Training Bundle comes standard with integrated BarkLimiter, a feature that utilizes Autorise technology that automatically adjusts the correction level needed to stop unwanted barking.
