Sprinkler performance data have been obtained under ideal test conditions and may be adversely affected by wind, poor hydraulic entrance conditions, or other factors. Published radius and diameter of throw performance are at nozzle pressure when tested at 1,250 feet above sea level. Your results may differ from the test data results obtained by Nelson Irrigation Corporation and Nelson Irrigation Corporation makes no representation regarding droplet conditions, uniformity, application rate, or fitness for a particular purpose.
