(Palmer Cap-chur Equipment) Designed to allow you to treat or immobilize animals safely in the field or feedlot, saving the time of catching or transporting them. Making use of a unique patented automatic syringe propelled by CO2 gas, you can propel 1 to 20 cc's of vaccine or medication to an animal and have the syringe inject the liquid on contact. CO2 propels the syringe from the gun, and a Cap-Chur charge inside the syringe expels the liquid through the needle on impact. After injecting, the syringe stays in for a short time, then falls out for easy recovery. Disposable Cap-Chur Aero Syringes do not require a charge. Comes with practice darts and instructions. The long-range gun is effective from approximately 15 to 30 yards, depending on the size of syringe used, and features 2 power settings for shorter and longer distance.
