The Dogtra 640X helps you train your dog off-leash up to 600 meters. This makes it the ideal choice for more demanding training of hunting and working dogs.
Correction type
The Dogtra 640X uses sound, vibration, and electrostatic impulse as correction. This can be adjusted in 100 levels. The alert for the dog can thus be really extremely gentle. Simply adjust the collar to suit your dog. You can increase or decrease the strength of the pulse at any time using the wheel on the transmitter.
