FOB (Foam On Beer) detectors pay for themselves in just a few kegs! Foam is beer - stop wasting it when a keg empties. FOB detectors sense an empty keg, and shut down the flow of beer in the line. Replace the keg, reset the FOB, and beer is flowing again. Multiply the glasses wasted per week by your profit per glass to see the money you could gain with a FOB detector.
