The Yard Gard LF emits a high frequency sonic tone that irritates pest animals, forcing them to leave the affected area. The frequency is high enough to be undetectable to most humans, and is user selectable between 15 kHz and 19 kHz at a volume of 90 dB @ 3 feet (most adults can only detect sounds up to 12kHz). It has a range of 4,000 square feet and is effective against a wide range of animals including rodents, squirrels, cats, raccoons, bats, deer and more. When not set to "Constant" the Yard Gard has a built-in infrared motion detector which activates the unit when pests move into the coverage zone (roughly 35' wide x 70' deep). The water and weather-resistant unit comes with a 30' 120v outdoor-rated power cord and also can run off 4 "C" batteries. This product comes with a 6 month manufacturer warranty. Batteries will last about one month on motion sensor mode. Adjustable settings: Frequency, range of motion detector, and constant vs motion sensor modes. Customer Satisfaction Guarantee: BirdXCanada offers a 90 day Customer Satisfaction Guarantee on this product less a restocking charge.

In cases where the product or its inclusions (including the product box, inclusions, cables, adapters, manuals, etc.) is damaged either cosmetically or functionally, there may be an additional restocking fee (as it will require repair, repackaging, refurbishing or new packaging before it can be sold again).

The restocking charge is a minimum of 15% if the RMA is requested within 30 days of the invoice date, 25% if the RMA is requested within 60 days, and 50% within 90 days.
