Every SHOOTING CHRONY® is made of 20 gauge steel but weighs less than 2½ pounds. It is powered by one 9 Volt alkaline battery (not included) and equipped with a large LCD-readout, 0.5" high. When folded, a SHOOTING CHRONY® measures 7½" long, 4½" wide, and 2¾" high. Every SHOOTING CHRONY® comes with an adjustable size, triangular shooting area from 8"×8" to 14.5"×14.5". The sides of the triangular shooting areas are made of wire-rods; the top of the triangle is formed by a 2¼" wide strip of tough, Hi-density polyethylene plastic, 1/8" thick. All shooting is done through the center of this triangular area, along the axis of the chronograph.
