Dakota Alert MURS Alert Transmitter Outdoor Monitoring System (MAT)

I had to tape off each side of the sensor in order to narrow the width of what the sensor was picking up. Hope that makes sense. Otherwise, it was picking up moving plants on a windy day, birds, leaves on the ground, shadows when the sun would move. That worked much better. The tray that holds the 6 AA batteries is too flexible and because it bends, it causes the batteries to loose contact with each other. I have had for about 3-4 years. I am now having to purchase a new sensor as it no longer works or works intermittently.
