    • The system is for use on outdoor firing ranges. Target cards bearing the printed targets are secured to a 4 ft. square panel made of Coroplast (trademark), which is extruded twin-walled polypropylene sheet. The sheet is formed with built-in curvature, which is sufficient to render the target panel rigid, even though the material is thin enough that bullets can pass through without punching-out. Because of the curvature, no frame is required to keep the panel rigid. Scoring rings are printed on the face of the panel, together with a centering device which comprises markings that allow an attendant to align fresh target cards with the scoring rings. Two or three plies of Coroplast may be welded/glued face to face, for larger targets.
    • 该系统适用于室外射击场。 承载印刷目标的目标卡片固定到由挤出的双壁聚丙烯片材制成的Coroplast(商标)制成的4英尺方形面板上。 该片材具有内置曲率,足以使靶板刚性,即使材料足够薄,子弹可以穿过而不冲压。 由于曲率,不需要框架来保持面板刚性。 刻痕环打印在面板的表面上,以及定心装置,其包括允许服务员将新鲜的目标卡与评分环对准的标记。 两层或三层Coroplast可以焊接/胶合面对面,适用于较大的目标。
