Perimeter took measures to make sure your signal field stays the same no matter how hot or cold it is! Patented Wire Check: This system automatically monitors your boundary wire so even if the wire is damaged your system will still work! With the built-in power output management, even the damaged wire will hold a consistent boundary field. If your boundary wire is completely broken this system will give you a constant (loud) audible alarm letting you know that your boundary wire has been broken and needs fixed! Patented Battery Check: Make sure you know when your battery actually needs replaced with Perimeter's advanced battery check - the system auto-checks your battery every two hours! Unlike other brands which only let you know when the battery dips below a certain level, the Perimeter system will notify you when 3 consecutive low battery triggers are set off. This is important because many times batteries can fluctuate in power levels due to different operating conditions and can set off a false low battery indication. No more wasting money replacing still good batteries! Heavy-Duty Waterproof Collar Receiver: The Perimeter collar is made of lightweight, high-performance polycarbonat
