Effective for lawns, gardens, ball fields, golf courses, and other areas pests disrupt, this battery-operated device repels moles, gophers, ground squirrels, voles, and other burrowing animals by generating sonic sound waves. It is humane an alternative to traps and poisons. It automatically generates sound waves (which become vibrations in the ground) every 15 seconds, convincing animals danger lurks so that they flee. Because varying soil conditions transmit sound waves differently, a switch permits adjustment to 300, 400, or 500 Hz, depending on what's effective. It covers up to 9,000 square feet. Watertight and ruggedly constructed of aluminum, the device goes completely into the ground so it can be mowed over. It measures 16-1/2 inches long and 1-3/4 inches in diameter. Two D-cell batteries (not included) provided 4 to 6 months of operation.
