Question:
What is the range the GG-002B group control can cover?
Answer:
If your house right in the center of control, then the coverage is 500x500x3.14=785,000 sq meters.
One hectare is 10,000 sq meters, so the coverage is 78.5 hectares. If you set up 3" valves right at the edge of the control circle, then the coverage will be even bigger.
