The Tannerite Pro-Pack is the best deal for the first time buyer because the catalyst mixes easily into each 1/4 pound target. Also, a free instructional DVD is provided with every order, which shows the legalities and requirements regarding the possession and use of this awesome product. Tannerite makes the safest and most stable binary reactive targets on the market. To achieve this level of quality, all targets are made in the U.S.A. with the finest materials available. Tannerite was specifically designed to be safe and non-flammable, whether it’s sitting on a shelf, being mixed or used. When shot with a high-power rifle, it produces a water vapor and a thunderous boom. Tannerite is the shot indicator target of choice for hunters, law enforcement, and U.S. armed services.
