The CD V-700 Model 7 is a kit to upgrade and modernize the Lionel Model 6B, Lionel/Anton Model 6, or Electro-Neutronics 6B with electronics derived from a recent version of the Ludlum Model 3 Geiger counter. The kit includes a new main electronics board with rotary switch, a connector for a detachable external probe, a wiring harness and switches to add new functionality and improved reliability to aging CD V-700s. The upgrade requires substantial modifications to the case. The State of Florida Department of Public Health has modified a large number of their CD V-700s to this standard.
The kit has the following ranges:
* x1   (0-0.5 mR/h or 0-300   C/m)
* x10   (0-5   mR/h or 0-3000   C/m)
* x100  (0-50  mR/h or 0-30000  C/m)
* x1000 (0-500 mR/h or 0-300000 C/m)
