Hello, After a few losses last year from foxes, I went and purchased "Foxwatch". Its supposed to send a high pitch tone that foxes, racoons ect. can hear and they stay away. It is supposed to have a "detection" radius of around 20 feet, but I notice that the red light does not go on unless I am about 10 feet directly in front of it. I have not had many fox problems since May so I am thinking it works somewhat. The batteries run out every 3-4 days ( its a pain ) I know my birds set it off all the time, but if I put it too far, it won't detect anything in the pen. Share your experiences with this product please
