The Super Pro #4 (like the smaller Pro Plus #4) is a specialized silver-eye repellent device.
Up until recently we've used two main sound types to control silver-eyes. These are the Electronic Scarecrow (ESC) and the Flower Fruit Scarer (FFS).
These sounds are harassment/irritants which apart from greatly disturbing the birds also blocks their communications. Both are very effective!
Now that we have a quality recording of a silver-eye distress call plus a butcherbird call (natural enemy of silver-eyes), we have built a machine which incorporates the lot. The Super Pro #4 has the two very successful silver-eye harassment sounds plus the butcherbird and the silver-eye distress - three machines in one.
Researchers at Melbourne University when using this machine as a part of their silver-eye research actually didn't even use the butcherbird part of the system for almost the whole 2002/2003 grape season as the harassment and distress sounds were doing a successful job without the butcherbird. Then right at harvest time when the migrating Tasmanian silver-eyes arrived in large numbers and started to overwhelm the system (it was an extreme drought year - remember) they turned on the butcherbird call and this provide the knock-out punch to move them out. They left within minutes!
As the butcherbird call is low frequency and the harassment and distress calls are medium to high frequency it is necessary to use two different types of speakers to assure correct reproduction of the respective sounds.
