Zon propane cannons have been used to scare pest birds and wildlife away from agricultural crops, airports, disposal sites and other critical areas for nearly 70 years. The Zon cannon produces pressure-regulated, 100-125 decibel sonic blasts to frighten and disorient pest birds and wildlife. Powered by economical propane, Zons are one of the most efficient means of wildlife control available. A standard 20-pound propane tank provides approximately 17,000 detonations. Operates unattended.
