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 weather-resistant NEMA-rated control box suitable for most any 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.
The sound chip is located on the faceplate so it can be easily changed in the field for protection against a greater variety of birds.

The control unit mounts easily to a post or pole using the included mounting hardware and bracket, and features two built-in amplifiers for high-volume, crystal-clear digital sound output. The two weatherproof speakers with cable allow many diverse sound coverage patterns, including long narrow applications. Each speaker effectively covers a cone-shaped area approximately 250 x 250 feet.

An occasional spray with electrical contact cleaner over the connection points and switches will ensure years of trouble-free use.
Storage
In the off-season the system should be stored in an insect proof container (e.g. a taped up box) to ensure that insects, ants or wasps don't build nests inside the control box or speakers as this may render the system inoperable.
