1. Victoreen CDV-700 Version 6A, with two 6993 GM probes, matching high sensitivity pancake probe, external matching speaker, operational check source. $200 OBO. The pancake alone is worth more than this brand new. Works.

3. Victoreen Thyac III Model 490. Case repainted. Last calibrated by Ludlum in 1994. No probe. Will accept any geiger muller or scintillator probe that works at 900V, BNC connector. You can find probes all day long on Ebay or the Yahoo Geigercounterenthusiasts group. $100 OBO.
Please allow around 30 dollars shipping UPS ground for each. Pictures on request.
I will include a NRC legal sample of uraninite ore with any of these (marble size or smaller).
