Crane scale has a large bright red LED clearly visible from long distances. It can be operated via the infrared remote control (which comes as standard) meaning it can be used from a safe distance away. Our Crane scales are battery powered, needing just 4x AA batteries that give over 120 hours' continuous use. Auto power-off helps save battery power. Hold, Tare and Zero features all come as standard, too - making this crane scale superb value for money.
