Expert Gardener 4-Gallon Home and Garden Pump Backpack Sprayer

I love this Expert Gardener 4-Gallon BackPack sprayer! The size if just big enough that it isn't too heavy will full of solution. It has adjustable padded shoulder straps, so it's comfortable while in use. The shoulder straps also have an adjustable attached waist belt to better secure the sprayer to your body. The pumping lever can be placed on either the right or left side during assembly (which is minimal and simple) and locks into place with a cotter pin. The leveroperates using a high efficiency piston pump, so your arm won't wear out keeping the flow of solution going. The sprayer sits on a black metal frame, so you can set it upright on the ground while filling the reservoir or for storage. The spraying wand has a locking trigger for continuous spraying, so you don't have to hold the trigger down to keep the solution spraying. The nozzle itself can be adjusted from a mist to a stream. This is a nice step up from a one gallon hand held sprayer and comfortable to use.
