As far as ET goes, is there any general consensus as to which system is considered more accurate,better, easier to work with? I have a commercial customer interested and he currently has 3 SRC timers installed one with 3 zones one with 4 and one with 6. Might not seem like much but each zone uses about 180 gpm so they are starting to think about trying to conserve. The system currently gets monitored by the maint. dept. that considers the lawn dry unless they hear that squish sound when they walk on it. I have no exp with ET so I will probably tend to go twords the Hunter sys. Any ideas?
