The Halo Outdoor Beacon works like other Halo Beacons to communicate its presence to any of your Halo Collars – at a range that you control using the Halo app. The Outdoor Beacon is ideal for outdoor use and/or where long battery life (3 years!) is needed. The Outdoor Beacon can be permanently mounted using supplied screws or adhesive, and can also be used indoors. Common locations for Outdoor Beacons include outdoor covered spaces, gates, fragile flower beds, docks, and garages.
