Figure 1 CDV-715 Retro Digial Geiger Counter
The CDV-715 has a perfect Cold War style case to house a modern sensitive digital Geiger counter, see figure 1. The Analog Digital meter displays Counts Per Second (CPS), Approximate Radiation Level in either imperial measurements (mR/hr) or metric measurements (mSv/hr). The top line of the display alternates every second between the approximate radiation level and the Counts Per Second (CPS). The 2nd LCD line is a power meter that provides a quick visual indication of the current CPS reading, more on this later, see figure 2.
