For isolated sites & power-restricted areas, the hunter node is the smart, reliable solution. The node mounts to a valve's solenoid quickly & easily, & without screws, drills or additional wires. The unit's solid construction & waterproof exterior ensure it can handle the harsh environment of a valve box. The node is powered by one or two 9V batteries & provides standard or extended power throughout the season. Along with exceptional reliability, the node features an easy-to-program LCD screen, the ability to control a master valve, & uses standard hunter controller programming with 3 programs & 4 start timesper program. The array of programming options & rugged reliability make the node a compact, but powerful irrigation controller with the flexibility of battery power.
