Modeled after a pistol, it fires farther with more precision than ordinary pepper spray. The pattern is subject-specific with a 14 inch spread at 16.50 Feet! It displays higher charge velocity to the target at 405 MPH. Instead of incorporating a canister for permanent pressure storage, JPX uses a cartridge to create the necessary pressure level to deliver the 10% OC (Oleoresin Capsicum) with 2.4% Capasaicinoids spray, eliminating any loss of pressure in storage. Additionally, the JPX performs homogenously over a wide temperature band. The JPX does not rely on electronics or battery power and is virtually impervious to environmental conditions giving you superior accuracy and no risk of deflection through a sidewind blowing in the wrong direction. Most pepper sprays that come from a can are susceptible to heat and cold limitations.
