Stay protected with the First Defense MK-9 1.3% HV Fogger from Defense Technology. Powerful, potent and reliable, it is no wonder that First Defense is the preferred pepper spray for law enforcement professionals. Ideal for crowd control and multiple targets, the sprayer employs a fog-style delivery for maximum coverage and near-instant target acquisition. The easy-to-use trigger handle provides a secure grip and effortless discharge--no struggling with flip-caps, or small activation buttons. Once deployed, the MK-9's powerful formula immediately inflames the eyes, nose, ears and throat of targets, causing temporary blindness and immobilization. Each canister contains 13-ounces of formula, sufficient for 14 bursts with am effective range of 18-20 feet.
