The stripes are connected with two flexible bands. By means of this construction, they well fit into every RyngDyng case.For calibration, the upper chessboard is pinned to the target at a central position using ordinary target pins. The lower chessboard is adjusted vertically using the markers.

This feature enables an RD600 system to observe and read the arrows on 4 targets in parallel. Examples are 4 3-spots, or, a combination of 3-spots and 40 cm targets.
