The ESC sound was itroduced in 1996. It's an intrusive high pitched siren type sound which ranges through a wide range of frequencies, right up to almost transonic.
is singularly the most successful and versatile sound in the
It repels more bird species than any other single sound. All our combination units
(Crop Gard, Pro Amp and X-20) which have several sounds in the one machine, include the ESC within the repertoire. It's simply too good to be left out.
The basic ESC unit can be used to run a sonic fence (a series of speakers 30m apart) made up of as many as 8 speakers thus forming a wall of sound 210m long. It can also be used as a part of a multi-blaster, which is a 4 way (360 degree) speaker run by 2 sound generators. This enables the unit to output 2 different sounds in a 360-degree circle. In either form (either sonic fence or multi-blaster), an 85amp fully charged battery will power the system for 2 to 3 weeks - non stop. Like all Bird Gard sound generators, the ESC is fully automatic having a light sensor which can be set (flick of a switch) to DAY, NIGHT, or 24 HOUR operation. No need to physically have to go and turn on in the morning and off at night - it's all automatic.
