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 locations. You can also use a part or full circle sprinkler with it. You have the choice of an independent solar rechargeable battery operated C-1013 controller, or a mesh controller with solar rechargeable batteries, RX2000-P. 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.
