This is not your cheap throw away model that you might get at a discount store. These are heavy duty, ready to work spot sprayers for the people who rely on their equipment to work. Spot sprayers are built with the same components that we use in our regular heavy duty sprayers and will give you many years of reliable service. We use Shur Flo pumps in either 1.8 or 3.0 gallons per minute with 15 feet of hose, and a high quality hand gun. Spot sprayers can be adatped to our four nozzle boom or boomless kit.
