Find worn or defective sprayer nozzles quickly
Check the pattern and coverage of sprayer nozzles in less than 10 seconds. Just hold the Mini-Patternator under a nozzle. The spray fills the 16 channels, causing small balls to float and showing you whether the nozzle is providing consistent, uniform coverage. For example, a good flat fan nozzle creates an inverted "V" pattern, so the center channels should receive more spray than the outer channels. A worn or defective nozzle won't give this uniform pattern. 18"L x 12"W x 1"D. Weighs 2 lbs. USA made.
