Radioactive Mineral Locator
I got this for $3.00 . I haven't been able to find any info on it yet . I put some fresh batteries in it and it seems to work . A little light flashes every few seconds . With headphones , you hear a click when the light flashes .

I bet there are collectors of this type of atomic age scientific doo-dads would pay substantially more than that. This is a completely uneducated opinion, but that is not something you come across every day. I wonder what system it depends upon for detecting radioactivity. I'd assume it works something like a geiger counter and has a gas filled container with gasses that respond to radiation. Great find!

Hey mojjax - the glass bulb looking thing in the upper left corner - is that a light-bulb or could that be the gass filled radioactivity detector?

Very cool. I couldn't find any info. on the company. Probably something you could order out of the back of a Popular Mechanics mag. back in the 50's. I think it's missing the wand though. Is that a plug for a jack on the front?

Looks like something that would be kept in a bomb shelter. Is there a date on the instructions? Very nice find.

Here is a Goldak model from 1948- Popular Mechanics - Google Books
Notice the headphones and the probe.

I think it was for prospecting in the "Uranium Rush". Back in the 50s some people thought that they were going to get rich prospecting for uranium.

Randazzo -The light bulb thing is some sort of sealed tube thingy .
Diggumup - The unit is the wand - the jack on the front is for headphones . I have a huge stack of Popular Mechanics , Pop. Science , Mec. illustrated . from the 40's , 50's , 60's I'll dig them out of the closet , maybe I'll find it in one .
Beans - Nope , no date
Mjlalt - I think you are right about ''Uranium Rush ''

It's a Geiger Counter. The Brass Tube in the bottom of photo two is a Muller Tube.
Every time you hear a click it is Radio Active Partical being detected.
Hold it up to your Smoke Detector and it will sing for you. LOL

Well I can tell you the company that made it is out of business. Just checked out the Pulaski rd address on bing. Just an old dirt lot now.

A mantle from a Coleman lantern will make it click too!

Remarkable good condition considering its age. Let us know if it springs to life when brought near a source of radiation. I believe an old luminous wrist watch dial may work.
If you want to sell it on eBay, the fact that you have the original instructions and warranty makes it a sweeter deal.
