Wireless Dog Fence F820 with GPS Chip

Wireless dog fence f820  New never used  The F820 GPS Wireless Dog Fence is a satellite-powered containment system that creates a customizable, circular boundary around your property without the need for buried wires. It features AI scene recognition, a lightweight design for dogs over 10 lbs, and three correction modes: tone, vibration, and static.  GPS Boundaries: The collar connects to satellites to establish a circular boundary. You can adjust the radius from as small as 25 yards up to 999 yards. Correction Process: As your dog approaches the boundary, the collar issues a warning tone. If they continue, it adds a vibration, followed by safe, progressive static stimulation if they don't return to the safe zone. Protection Mode: If your dog runs through the boundary, the collar limits the correction cycles and enters a 30-second protection mode to prevent over-correction.
