Apparently the Cold War is over… or at least a Federal regulatory agency apparently thinks so! We were lucky enough to pick up a few of these “Geiger Counters” from a Federal Warehouse from which they were distributed to Fallout Shelters and civilian “Bomb Shelters” around the country during the Cold War. The unit is marked with the Civil Defense logo – a blue circle with a white triangle and red letters CD in the center of the circle. This unit is being sold as NON-FUNCTIONAL. That means it will make a great display piece or if you are great with electronics perhaps you can repair it.

These units are in good condition, however, we do not warrant their functionality, accuracy or performance in a gamma or beta environment, or otherwise. In the unlikely event that a maintenance issue would occur, the manual (reprint) has a rather extensive troubleshooting and corrective maintenance section, including repair and replacement of resistors, diodes, etc. To download a reprint of the original Operator’s Manual for this unit click here.

Units may or may not come in an original box and may or may not include an original manual. This is a non-returnable item.

Use of the term “Geiger counter” is in place solely as a buzz word. Many people recognize the term “Geiger counter”. What you are getting is described by the model numbers listed. Please research the capabilities and specifications of these specific model numbers before making a purchase. We do realize that some of these units may not be technically considered to be Geiger counters, rather radiation detectors.

    I ordered the “Non Working” CD Geiger counter to ad to my old cold war era display. Once again, to me surprise, Colmans came through with flying colors. Not only does this thing look like it just came out of the box, but after a quick look inside, I cleaned up battery contacts, popped in a new D cell, and shazam! This thing works (at least on test mode) this is a great buy for only $19 bucks (even for a non working unit) My expectations have been exceeded again.

    Very disappointed with mine. I guess “Non-Functional” means it’s okay to have the meter face written on with a sharpie.

    Useless brick, non-functional, even when contacts cleaned with fresh battery.Don’t waste your money!! Couldn’t use for spare parts as not known which parts do not work-maybe all!
