This high accuracy, high precision Pinewood Derby Digital Scale is offered by SuperTimer as part of our mission to give you all the tools you need for a truly successful Pinewood Derby. Powered by just two AAA cells and capable of weighing up to 17 ounces, our Pinewood Derby Scale measures the typical five ounce Pinewood Derby car to 5.00 Ounces! Just turn it on, set the scale to Ounces and weigh away. Even the height and size are ideal so that the car can be placed on the scale right side up and not roll off. Includes cover and protective pouch.
