The portable, hand-operated Trombone Tree and Shrub Sprayer, designed primarily for the chemical spraying of trees, shrubs, and low-growing plants, can also be used to wash down structures, windows, vehicles, etc., all without having to either climb or stoop over. Its 72-inch-long hose with large intake-straining filter, which drops directly from the chemical bucket or drum or a multi-purpose pail, produces from a fine mist to a long-distance stream (reportedly up to 40 feet outward, 25 feet upward) when the nickel-plated brass pump is slide-activated by simply pulling the gun-type grips. The cylinder/plunger/air chamber pump delivers 2.7 ounces of material per in/out stroke and 150 psi of pressure.
