These studies have led to the development of the "Electronic Guard," a battery –powered, siren-and-strobe scare device that has been available from ADC’s Pocatello Supply Depot (PSD) since 1991. As of May 1995, the sale price is approximately $260 each. Two hundred seventy five units have been sold to date.

Field tests of prototype siren/strobe devices on high mountain summer range yielded average reductions of 60 percent in coyote predation, compared to pre-test periods (Linhart et al. 1992).

During the late 1980’s, the ADC program implemented a plan to encourage the use of guard dogs in concert with other means of depredation control. The initiative was successful and most livestock producers served by the ADC program have tried or are using guard dogs.
