In order to be effective in crowd control or even in self-defense, you can't just assume that you will get it right the first time when under the stress and heightened stakes of a real-life incident - you need to train for that kind of accuracy. Mace's TakeDown Inert MK-IV Foam Training Spray gives you that opportunity. This MK-IV canister measures 6.25'' x 1.50'' and contains up to fifteen bursts to take down your assailant training partner. The spray delivers at a range of 8-12 feet in a jet stream of foam. Mace makes the flip-top cap with a spring loaded mechanism for safety.
