The Concerto will cover an area up to 4000 square feet within minutes. Simply plug the unit into an electrical outlet and turn on the switch. The Concerto will quietly do its job without further attention! The Concerto's rechargeable lead acid battery allows approximately 36 hours of convenient portability and will not develop a "memory" as so some other appliance batteries. It is also adaptable for voltages in Europe, Australia, Japan and other countries.
The Symphony will treat approximately 1000 acres using a tree as a broadcast antenna.
Using solar power, there is virtually no cost to run and maintain the unit.
