Description This hidden W-227b is among the most reliable, cost-efficient pet containment systems available today. A buried wire transmits a harmless radio signal. When you dog approaches the boundary, the signal causes the dog`s collar receiver to deliver a warning beep first. If your dog continues closer to the boundary, the system will issue a mild shock. If your dog continues further, the system will issue stronger shocks until your dog returns to within the boundary you have set up. Your dog will naturally seek to avoid correction, and is content staying within established boundaries Highlights:Pulsed proportional stimulusProgressive tone stimulusVariable field width controlAudible and visual wire break indicatorsSpeed detect anti-run throughBuilt-lightning protectionMultiple collar perationUp to 5000 aquare meter range(over 1.2 acre) What 39;s Included In The Package1 x Indoor wall-mounted transmitter;1 x Power plug;1 or 2 x Adjustable Rechargeable receiver collar;1 x usb cable1
