Halo Collar 5 Powered by Precision+: No other wireless dog fence combines dual-frequency L1 and L5 satellites with real-time ground-station corrections. A global network of ground stations sends real-time corrections to your Halo Collar, delivering GPS accuracy within 2 feet of your dog's actual location. Dual-frequency GPS, drift prevention, and proprietary AI obstacle filtering do the rest. Subscription required to activate GPS & fence features: Your Halo membership unlocks GPS tracking, unlimited cellular data, virtual fence creation, training guidance, live support, and activity reports. Choose your plan after purchase to enable tracking and containment. Know where your dog is the moment it matters: Know your dog's exact location 24/7 with AlwaysOn GPS that comes standard with every plan and never stops tracking your dog. Get instant smartphone alerts if they approach or cross a boundary. Built for all yard sizes, rural properties, and wide-open spaces: Advanced GPS technology works with Wi-Fi, Bluetooth, and cellular connections to keep your dog's location updated 20 times per second. Create and store multiple fences, even on rural properties, hiking trails, and remote locations where other GPS collars fail. Professional training guidance built-in: An exclusive training program by Cesar Millan teaches any dog to understand the automatic sound, vibration, and static (optional) warnings they receive as they approach a boundary. Longer battery, faster charging: All-day battery life keeps your dog safely contained between charges. Rapid charging happens in about 1 hour. Fits small, medium & large dogs (10 lbs and up): Adjustable 8–30 inch collar ensures a secure fit for most breeds. Waterproof (IP67) and built for active dogs who run, swim, and explore. Works without wires or base stations: Unlike traditional wireless dog fences that need a plug-in transmitter, Halo Collar is entirely self-contained and works using satellite and cellular connectivity. Take it anywhere without hauling equipment. Create a new fence in seconds from your phone (with sizes ranging from 900 sq. ft. to 1,200 sq. miles), whether you're at home, a friend's house, or a campsite. Meet the next generation of smart dog safety. Halo Collar 5 combines a wireless dog fence and GPS dog collar in one system, giving you the freedom to protect your dog wherever life takes you. Unlike traditional invisible fence for dogs systems that rely on buried wires or limited circular boundaries, Halo allows you to create custom shaped wireless fences directly from your phone. Whether you are at home, traveling, or on large open land, your dog stays safely within the boundaries you set. Powered by dual frequency GPS and Halo’s PrecisionGPS technology, Halo Collar 5 delivers reliable accuracy you can trust.

It is not just about containment, it is about building better behavior and a stronger bond.
