I am going to incorporate some new irrigation into my golf course. I would love to pull wire back to a contoller for the valves. Unfortunately, this is not in the cards. One thing that was suggested to me was a Hunter wireless valve system with a remote programmer. Are these things reliable? Are they built to last? Any other information on them? I am not into Mickey Mouse gadgets that are going to be a nightmare to maintain. Lay it on the line for me fellas.
