The Voyager is the #1 consumer choice for medium to large area gear drive sprinkler heads. It covers areas from a 25 ft up to a 45 ft radius in a part- to full-circle spray pattern. Adjustments only require a flat-head screwdriver, not a special adjustment key. The gear drive rotor ensures even and complete water coverage as well as a quiet spray. A filter protects the nozzle from clogging and is easily accessible for cleaning. It is compatible with all major brands of gear drive rotors including Rainbird, Hunter, and Toro.
