Cut flatware loss by at least 80%
Patent Number 6833789 $699.95 Body: The body of the unit is constructed of high-density ABS plastic. The ring is sloped to the center opening of 8.5 inches. The edge of the ring is flanged to securely fit the top of standard Rubbermaid 32 to 55 gallon trash cans. All electrical components are housed in the protruding square on the side of the ring. Metal detecting coil: The metal detecting coil is securely fastened to the inner ring of the unit. The coil is potted in an epoxy compound protecting it from both moisture and food particles. Digital Counter: The FRS Flatware Detector is the only Flatware Metal Detection System to incorporate a digital counter to assist in the monitoring of flatware loss. The digital counter can only be reset by management personnel with a security key. This unique feature not only helps in tracking flatware losses but also reinforces employee diligence to help in preventing losses during disposal of waste. Electrical Components: The electrical components are located in a protruding square on the side of the unit. All components of the electrical system are potted in an epoxy compound to keep them safe from moisture and food particles.  FRS Flatware Detector Features Adjustable intensity: The intensity of the metal detection is fully adjustable, allowing each customer to fine-tune the unit for their specific flatware and kitchen environment.

We believe this is a very important feature, because repeated false alarms could lead kitchen and wait staff to eventually ignore both the real and false alarms.
