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 do some other appliance batteries. It's also adaptable for voltages in Europe, Australia, Japan and other countries.
The Symphony™ will treat approximately 1,000 acres using a tree as a broadcast antenna. Using solar power, there is virtually no cost to run and maintain the unit.
