I recently bought a metal detector/stud finder for that exact reason. I also am an electrician and have to find studs or rebar often when drilling and it’s been great for that too. In your case it would work by detecting the nails in the studs instead of looking for the studs themselves. I got the Zircon Metalliscanner (I believe)
I think I was literally using that exact same stud finder. We were getting very sketchy hits on where the studs were located, so we started probing and found the issue.
