The M8 is the industry standard used by more bird and wildlife control experts than any other bird control LP gas cannon. The M8 Bird Control Multi-Bang Cannon works by producing random series of single, double and triple clusters of bangs. The ignition generates as many as 200,000 shots, and the M8 cannon is capable of producing 5,000 shots per five gallon LP gas cylinder. The use of many shots at irregular intervals over a short period of time has been proven as one of the more effective methods of bird and wildlife dispersal. The use of ear protection is recommended when operating the M8. It is designed to be fired in an open field and placed on a flat ground. For best safety practices, do not operate the M8 near dry vegetation or material. For best results, change locations and vary the rate of fire often. Powered by standard LP gas cylinders (NOT INCLUDED)
