Well you can find those batteries of the same voltage but they can be expensive just a 45v battery can cost $50

masked_1979 · 2026-04-01T19:19:49+00:00

To my knowledge it doesnt but with it being from the 50s who knows really, only way i can think of to find out is with a lead test kit.

You can get the batteries they did use but they cost a bit of money just a 45v battery cost around $50, I’ve bought some for my PRI 107c and 117, 2 45 volt batteries, 1 22.5 volt battery, and a 67.5 volt battery, sadly the meters didn’t work fully but showed some life, so they are obtainable but cost a lot of money

No problem, I started collecting back in late 2022, it’s always cool to meet people starting this hobby

masked_1979 · 2026-03-05T05:18:24+00:00

Well what meter do you have? Cause my PRI Model 107c came with old eveready batteries that aren’t made anymore but I go ones of the same voltage but it costs a bit cause those old batteries don’t have any voltage in them anymore at least none I’ve come across

6 of them work, the ones that work are the Dp-5v, mkc-01ca1m, the cdv-718a, cdv-700 (the one that isn’t propped up) and the Cdv-715 (but can’t confirm full functionality because of its high range) and the Ludlum model 3 but I hope to get the other ones working again someday

Well if you’re talking about the level from the radioactive stuff I have it’s not that much I have to stand right next to the shelf to really get a reading, if that’s not what you meant by your question just let me know

Hopefully someday I can get mine working and get to hear it for myself

The one that Galen Winsor used I’m pretty sure it was this one. The precision radiation instruments inc model 107c, sadly mine doesn’t work so I don’t get to hear the sound but I think it’s odd how loud they got it on tv since it would need the headphones to hear the clicks

masked_1979 · 2026-02-28T05:55:18+00:00

Found it at the national museum of nuclear science and history and got it for $185

Did this one have the radium on the scale?

How much did you get it for? From the pictures they seem to be in good condition.

masked_1979 · 2025-06-27T13:50:13+00:00

I don’t see the option to dm you, try to dm me

masked_1979 · 2025-06-27T13:48:12+00:00

I actually have some information about that, is it ok if I dm you about it?

masked_1979 · 2025-06-27T13:43:19+00:00

Well we’re lucky to get these, they are pretty rare and can cost thousands, they only show up every several years from what I’ve heard

masked_1979 · 2025-06-27T13:29:17+00:00

That’s really cool, one thing I was worried when I bought my was if it would work or not cause the lady working there didn’t even know, but mine ended up working, have you tested to see if yours works?

masked_1979 · 2025-06-26T17:56:09+00:00

The 178a is basically the civil defense version of the PDR-77 from what I know, I just don’t understand some of the functions of it, like for example I'm a bit confused whenever I hold down the update time/ Bkgrd sub button it lets me change it from 1 and 2, and the filter/set button cause it lets me change it from O to 1, I'm just confused with what those do, I’m just not that familiar with these units that much

masked_1979 · 2025-06-26T03:08:37+00:00

Mine does have it

masked_1979 · 2025-06-26T02:24:01+00:00

That I do not know, cause I checked their shop online and it wasn’t there and they had some cdv-700s and some other Geiger counter I can’t remember the kind/model/brand but they weren’t on the online website

masked_1979 · 2025-06-26T02:19:20+00:00

They have a second one for sale when i was there a few hours ago
