Deter birds and other wildlife with the Zon Mark IV Scare Cannon. It is also one of the most ÂÂextensively used bird deterrents at agricultural, industrial sites, and airports around the world. Protect up to six acres of high-value crops (such as ripe fruit) from determined birds. Provides even greater coverage for lower value attractants.
 The Cannon delivers 17,000 explosions per 20lb propane tank. Cannon also includes an integrated interval self-timer and is powered only by a propane tank.
Upgrade Your Cannon with the Rotating Tripod for 360° coverage. The Rotating Tripod elevates the cannon above crop vegetation and other obstructions. The Zon Quartz Clock Timer allows you to set the cannon so it fires when it is needed and stops when birds are not active. Reducing noise when birds are not feeding prevents them from becoming accustomed to the sound, increasing the effectiveness of the cannon.
