The G-Set product is perfect for the irrigator who wants a "set it and forget it" operation. This post mount option is ideal for pivot corners, fence lines, remote or hard to get to get to locations. You have the choice of an independent rechargeable battery operated C-1013 controller with solar back-up, or a mesh rechargeable battery operated RX2000-P controller with a solar back-up. The C-1013 controller can be programed to turn on and off at a predetermined time each day as long a water is supplied and the sun shines. The RX2000P controller offers the same benefits with the added benefit of being able to reprogram your controller from a distance. Most controllers are set for a 30 minute operation schedule each day.
