It uses a dual-tank system that keeps concentrate and water separate, mixing them automatically at the point of spray. A dial controls concentrate flow rate for precise ratio adjustment. The hand-pump pressurization system reaches up to 60 psi, delivering spray coverage up to 25 feet. Three included nozzles offer cone and fan spray patterns, giving applicators flexibility across different treatment scenarios. The wand and tank are polyethylene construction, with reinforced PVC hose and Viton gaskets for chemical compatibility.\u003c\/p\u003e\n\u003cp\u003eThis sprayer is suited for turf care professionals, agricultural operators, nursery workers, and experienced DIYers who treat multiple zones or switch between chemical applications in a single session. The mix-on-exit system allows swapping concentrate tanks between applications without draining, cleaning, or reconfiguring the main tank. This makes it practical for properties or operations where multiple chemical products are applied in sequence. The 6-inch fill opening simplifies refilling, and the in-tank filter helps prevent nozzle clogging during extended use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMix-on-exit dual-tank design keeps concentrate and water separate until point of spray, reducing material waste\u003c\/li\u003e\n  \u003cli\u003eAdjustable concentrate flow rate dial for precise mix ratio control\u003c\/li\u003e\n  \u003cli\u003e3 nozzles included with cone and fan spray patterns for versatile application\u003c\/li\u003e\n  \u003cli\u003e60 psi maximum pressure with up to 25-foot spray distance via hand-pump mechanism\u003c\/li\u003e\n  \u003cli\u003eViton seals and gaskets provide broad chemical resistance for fertilizers, herbicides, and pesticides\u003c\/li\u003e\n  \u003cli\u003e4-foot reinforced PVC hose and brass nozzle components for durability in field conditions\u003c\/li\u003e\n  \u003cli\u003eIn-tank filter reduces clogging during extended spray sessions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with non-foam liquid fertilizers, herbicides, and pesticides in residential lawn care, garden maintenance, and agricultural applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis sprayer is operated and serviced by landscape professionals, turf care technicians, and agricultural applicators.
