Tracking collars, such as the ones offered in the SportDOG TEK series, help owners locate their dogs when they’re off retrieving downed birds, etc. They have a 7 mile tracking radius, report the direction the dog is moving in, and they even report when the dog has stopped movement. This dog training collar and other collars such as these are beneficial when training a dog for hunting purposes. However, these tracking collars are most ideal for hunters trying to find their dogs in the heavy bush, in vast fields, or in the trees. Spend less time finding dogs and more time hunting.
