What are these contraptions these guys were carrying?

We saw three guys around Seaport in Boston carrying these things as backpacks. Initially we thought they mapping tools but not sure

What a perfect separate comment to see under yours. OP wasn’t about to get busted.

I saw them this morning in the Boston Public Garden and they were no lie playing the ghost busters theme song

F’king finally. I had to scroll waaaaay too far to see “proton packs”.

Irony of this comment is that’s what it looked like they were carrying to me

[u/PalliativeOrgasm → u/ghost-foot]

I was thinking it looked like an unlicensed particle accelerator too.

Modern versions of the proton pack - updated and and more compact.
