Bird Gard - Model Pro Plus - Electronic Bird Control Unit - Brochure

Bird Gard Pro Plus features two high power amplifiers and two external speakers for crystal-clear digital output.  The solid-state electronics are mounted inside a NEMA-type control box that is suitable for most any weather condition.  The Bird Gard Pro Plus is fully programmable, with adjustments for volume, specific sound combinations, daylight, night, or 24-hour operation.  Every six seconds a randomly selected sound is broadcast at a randomly selected frequency out of a randomly selected speaker.  It sounds like there are many different birds in distress spread throughout the protected area.  Also included are four different random features that vary the sound, the sound duration, length of time between sounds and the sound location so birds don`t get accustomed to the sound pattern.
