Hunter Industries is a manufacturer of irrigation equipment for the landscaping and golf course industries, based in San Marcos, California. They are the second largest employer in San Marcos after the San Marcos Unified School District Hunter produces pop-up gear-driven rotors, spray sprinklers, valves, controllers, central controllers and weather sensors. The company reports that it holds more than 250 product patents and 40 trademarks, and conducts business in 125 countries. The company was founded in 1981 by Edwin J. Hunter and Paul M. Hunter, to produce a compact landscape sprinkler called the "PGP" (an acronym meaning "professional gear-driven pop-up"), which was the first sprinkler to utilize "matched-precipitation" regardless of the radii or arc. The former president and CEO was Richard E. Hunter, Edwin’s son. Richards son, Greg Hunter, is the current president. Hunter Industries products are used in a wide array of locations including sports stadiums, national landmarks, hotels, and city parks. Besides their involvement in the irrigation industry, they also offer products in several other industries, such as customer manufacturing, landscape lighting (through its acquisition of FX Luminaire in 2009), and the medical industry. They operate manufacturing facilities in both San Marcos, California, and Tijuana, Mexico as well as having overseas offices located in China. They previously operated a manufacturing plant in Cary, NC, from 1992 to 2009, the plant closed due to poor market conditions at the time.
