Viper2bn - 3/20/2020 10:40 I have had my pinpoint system for 5 years, I usually need to replace at least one coil per day and have as many as 9 in a day. The turn compensation is nice and it does save chemical but I have had nothing but trouble with it and the system is now shut off while I wait for yet another hub. I run 28% through it frequently and the valves have not been a problem as long as you don't leave booms full of chemical for a long time. I have had enough of the system and will be taking it off and putting my 5 way bodies back on, when it works correctly it's a great system but it's a costly system to run.
