Create instant wireless fences anywhere in the world on satellite maps with zero buried wires. Developed with Cesar Millan for humane pet containment.
Installing a physical wooden fence around an acre of land can easily cost $8,000 to $12,000. The Halo Collar 4 replaces all of it through satellite technology. Using the phone app, you simply tap boundary points on a satellite map around your property line to create an instant perimeter.
When your dog approaches within 7 feet of the boundary, the collar emits a warning sound. If they keep going, a gentle vibration prompts them to turn back. Halo 4 upgraded to dual-frequency GNSS chips, which eliminated the boundary drift that affected earlier models. For rural properties, farms, or frequent campers, this is freedom in a collar.
During our 30-day testing protocol with cats and dogs, we evaluated this unit across the practical metrics pet parents care about most:
