I prefer the "kiss" way of plunger operation but can get you more than that if needed. Have simple on/off, plunger lift specility type controllers or controllers where you can enter well depth,starting off time and some other specifics to your well and the controller will optimize plunger operation without your being there. Will also repair old FB/Logic Digitrol controllers. My best selling dual pad plunger is hard to beat under typical well conditions, but if you have down hole issues many options are available.
