OCD-P-108 PROBE HOUSING FOR CDV-700M CIVIL DEFENSE GEIGER COUNTER CONVERSION - $24 - (Gonzales, TX)

This is a new old stock OCD-P-108 probe used to convert a stock CD V-700 to a CD V-700M. When properly done with the correct GM tube it makes the instrument much more sensitive and can be used for alpha contamination surveys. We made several 700M Electro-Neutronic model 6b geiger counters over the years using the LND 723 GM tube without modifications to the instrument circuit boards. DOES NOT INCLUDE GM TUBE
