A professional dog trainer, Pat Nolan takes the Dogtra ARC Handsfree to a retrieve training session to talk about how it changes his training sessions by having a controller at your fingertip. The ARC Handsfree is a 3/4-mile range e-collar, paired with a Dogtra Handsfree Remote Controller that gives you the freedom to multitask and have discrete control during field operation, making it perfect for hunting dogs and police K9 professionals.
