The G2 Chronograph features an inverted system that is capable of measuring in adverse light conditions making the measurements more accurate than conventional chronographs, even indoors. Its light sensors are spaced apart for more accuracy and the sunscreens have self-contained LED lights when a little extra light is needed. This system is collapsible and compact, for quick and easily deployed from its heavy duty storage case. Higher accuracy was achieved by using a high speed 48 MHz processor and by designing a circuit with an advanced data interface that allows each unit to be computer calibrated at the factory after assembly. It comes with 1/4-20 dovetail plate to attache the chronograph for quick assembly.
