Best for: Drywall hanging jobs where screws mark the stud and batteries are a nuisance.

Questions, answered
Is a cheap electronic finder better than a magnet?
On plain drywall with careful calibration, it adds wire warnings and center marks. On any tricky wall, the magnet is more trustworthy.
What is the cheapest safe setup for heavy hanging?
A magnetic finder plus a test-nail verification habit. Verification beats price tier for safety.
Why do budget finders need 9V batteries I never have?
Legacy design economics. Keep a spare 9V taped to the tool, or buy the magnetic finder and end the problem forever.
Can I use my phone as a stud finder instead?
Phone magnetometer apps find screws crudely, similar to a weak magnet finder. They are a backup, not a tool.
