An apparatus and method for displaying the weight or cost of an uncut selected segment of an item involves passing a position indicating member over the item lying on a support surface. The position indicating member carries one or more sensors which generate signals corresponding to cross sectional contours of the item as the member is traversed along the item from a reference position to a selected other position over this item, defining the selected segment of the item. A motion detector arrangement preferably comprised of one or more microelectromechanical accelerometer devices generates signals corresponding to motion of the position indicator support member as it is moved along the item. These signals are processed in a signal processor to determine the volume of the segment of the item lying between selected successive positions of the indication member. The segment volumes are converted into numeric weight or price values.
