The Prima Tech 12.5ml Dose Drencher is a robust, versatile dosing gun used for drenching cattle in all environments. The V-shaped injector is easy to handle and makes administration of medication accurate. The reverse dial-a-dose selection allows changes from small to large doses without any product wastage. Squeezing the handle slightly helps to get the desired dosage amount as indicated in the dosage setting window by turning the dosage adjuster. A slight squeezing pressure will help ease dosage adjustment. The pack is supplied with 3 draw off caps, 5'' or 3" nozzle and soft medical grade tubing.
