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 used to ride my bike a lot when I was young to the point where it became my automatic thing to do whenever I was feeling stressed/anxious/depressed. The adventures I went on, while also being outside in nature and in the sun (or moonlight) would always pick me right back up.

I only realized this recently as I’ve had a huge urge to buy a bike again but didn’t know exactly why.
