biometric seals were probably an aftermarket change made by vault-tec in vault 101 for whatever reason. But having two of the same model be not exactly identical is actually pretty common due to region differences. In one country you might have the exact same model of something but it has a slight change because of the region, like power adaptivity etc. So even if the model in F3 and FNV are the same, that doesn't actually mean they have to be exactly identical. "Model" really means the blueprint it is based on, rather than it's exact end-result.

I think a very simple, yet effective way to explain the PipBoy is the Vault Tec experiments. Vaults had different experiments so they might have been given different PipBoys to reflect that. Vault 101's experiment was that it was supposed to be sealed permanently. The Overseer was purposely given this "all-seeing" god status so a PipBoy being biometrically attached to your wrist would make sense. You're not supposed to leave and the Overseer possibly had direct access to monitor the Dwellers, so it's biometrically sealed to prevent anyone from taking theirs off and trying to go off the grid. Maybe it sends personal data to the Overseer so he has all the realtime information he could need. Someone dies? The Overseer knows immediately because the Overseer knows all. Gary's Vault is literally just one guy, except he's been cloned. If someone other than Gary shows up, the PipBoy's can communicate that to each other. Vault 21's PipBoy (where Doc Mitchell got his) could be taken off, possibly so it could be gambled away if someone chose to do that. Vault 13 was a control Vault, there was no experiment, so they got the PipBoy with the most functionality that can monitor the most data. Vault 111 was never supposed to have Dwellers so their PipBoys were meant solely for Vault Tec staff, who might need to open any given Vault at any given time for research purposes. Maybe each Vault got a specific model of PipBoy for a specific purpose related to their specific Vault experiment.

5:14 it might just be 101 having a creepier variant than others

Only watched a couple of these so far but the quality and subject of these videos are great and extremely interesting, respectively. Keep up the good work sir :)

What about 76 ?

Nice video, you got yourself another subs

Very cool

Christine from New Vegas' Dead Money DLC specifically states that there is a fission battery in the Courier's Pip-Boy so it has been confirmed in game for the 3000 model at least.

Binging your vids waiting for Starfield, cannot wait

Hearing about the Biometric seals made my arm feel "uncomfortable". to hear about something being locked onto until you die is horrifying! D:

Great video

Good listen on my way to school :)

❤

my question still remain is.. how did the pip boy in fallout 4 reset itself? wouldn’t it have the stats of whoever we looted it from?
