The HLKJJY is a wireless containment system that uses a collar and a base unit to keep a dog inside a set radius, with no wire to bury. It claims over an acre of coverage, a rechargeable collar and an adjustable correction level, and it ships with 55 boundary flags for training. Wireless fences suit renters and owners of large, flat yards who want a quick setup, but they are less precise than buried-wire systems and the signal weakens near metal buildings, slopes and dense trees. Expect several weeks of flag-and-leash training before a dog respects the boundary.

This is a wireless dog fence system with rechargeable, adjustable operation and coverage of 1+ acre. It comes with 55 flags to mark the boundary.
When a dog strays beyond the set range, a corrective stimulus encourages it to stop and return within the boundary. With repeated training sessions over time, dogs learn to stay within a safe area.
