Decoder installations continue to be one of the fastest growing forms of technology in irrigation control. A key advantage over conventional systems is that decoders use less wire than conventional systems. That in turn means lower cost, faster installation, simpler troubleshooting and easier repairs. Systems can be easily expanded with minimal digging and disruption of landscaping by adding in more decoders rather than running additional wires.
Surveyor ™ and AGC  enable you to take advantage of this cost-efficient approach with the two-wire decoder version of the controller. The D-series decoder is available in your choice of 1, 2, 4 and 6-station outputs making it possible to run each head on an entire green with a single decoder. In all, decoders let you operate up to 99 stations out to 3 miles (4½ km) from a single controller. You can even mix decoders with your conventional system so they are ideal for system retrofits.
D-SERIES DECODERS WITH AGC CONTROLLERS
Independant control of up to 99 decoder station outputs. Because each station can run up to two Hunter VIH sprinklers, one AGC controller can manage up to 198 heads.
Extend control up to 3 miles (4½ km). with a single cable.
Sprinklers can be placed up to 150 feet (45 meters) from the decoder.
Hunter's exclusive DIH rotor minimizes valve boxes and offers easy decoder replacement without turning off the water.
