Pokemon English Booster Pack Weight Database
This database is amazing and very helpful. But why aren’t electrician’s metal detectors more commonly used? It’s something I rarely see discussed, but it’s possibly more reliable than weighing packs?

I havent heard of that method. I assume its based on the foil cards being slightly metallic and therefore detectable? The packs themselves are foil so if I had to guess thats why it does not work
Yes, you’re right. Detectable because they have foil.
The dectector’s sensitivity can be adjusted, so it can account for the foil of the packaging. I have a video, using it on Base Set packs, on my iPhone but struggling to upload because of the format.
But a video of someone using one on more modern packs can be found here, when the topic was briefly discussed:
EDIT - Here is the Base Set Video I mentioned

I guess it might work for Gen 1 sets but after that no, because the pack may just contain a non-holo Steelix or Metagross or something.

Ive avoided discussing it publicly because of how people can change the odds from a simple weight that can vary to a more sure thing. Personally i dont think its something that should be spread because i like the uncertainty to still exist.

It’s inevitable
errrr can it be done with blisters?
I can’t speak for the packs you’re referring to. But I have successfully tested it on:
Base
Fossil
Jungle
Base Set 2
Skyridge
Works but doesn’t distinguish between Holos, Alt Arts, V Cards and Holos:
Chilling Reign
Fusion Strike
Evolving Skies
Eevee Heroes
Less successful, because of the additional slots for Trainers etc.
Hidden Fates
Cosmic Eclipse
Lost Origin

Ok that’s it, imma buy me a metal detector bigger then me body to “scan” all packs in the card and toy shops, almost knocking everything around me out with it trying to find me a heavy boiii

I do think if such a thing exists, people should be informed. No doubt some people sell heavier packs, whilst with the knowledge they definitely l don’t contain holos.
I imagine you need a decent sample size to calibrate the detector for each pack foil. At that point you also have a weight sample size that is large so I think that is why people never bothered

I would be curious how much better it works compared to weighing, like what’s the sensitivity and specificity? That would be incredibly helpful to know.
Replace “disease” with “foil.”

Or a known light and heavy (for a specific set) should suffice as a control.
Someone get this man an amazon affiliate link to put in the op

False positives certainly happen. Also there is the element of human error and quality of the metal detector.
Don’t have an expensive metal detector? Read on!
Did you know that the packets which house the cards can actually be opened? Simply tear the packet at the top, and once opened, you can remove the cards inside. The foil card is usually towards the back of the stack of cards. Simply go through the cards one-by-one to discover if you have one of these elusive “hits”!

No, no no you did not have to pull this chart out. I come to E4 to relax and to take my mind of me midwidery studies, and not to remind me of the RESEARCH PART OF IT 
-all jokes aside; never thought we could use this for…Pokemon… how interesting!

I’m interested for sure. A few different methods of modern pack “weighing” have been tossed my way over the last year or 2. Some with more success than others.
Nothing seemed definite though. This seems to be a lot more concrete. I’d like to see it tested on the very hard sets to weigh like DF or PK
