These hand held units are designed for tossing. Lock-On style for continuous discharge of contents ideal for control and dispersing of crowds or for securing of a confined area. This is also available in a 2-ounce size. FOX premium defense sprays provide the fastest-acting, and most reliable formulas available. They also use the largest nozzle openings, meaning instead of discharging only a gram or less of formula per ½ second burst, these units discharge an astounding 3 grams! The primary benefits of discharging a greater volume per burst are increasing your odds of hitting your assailant in the face and eyes with the incredible FOX formula, thereby stopping them faster. Remember, no matter how good the formula, if you do not hit the subject in the face and eyes, you greatly reduce your chances of stopping them as fast as you would like to do.
