Does one realy need a 185? I have always rented a 185 and I own a 150. The biggest system we do is an athletic field ( actualy 3 fields in 1 system) 2 in pvc, 4 heads per zone.2 different set ups. One setup has a much better well so it runs 2 zones at once but I can always dissconect wires and blow 1/2 then reconnect the other 8 and blow that. Looking to buy a second and Im looking a a 125. Will I be sorry I dont have access to a 185?
