Reply to comment by Deftek178 in How do I find these g-d studs?? by WaterChestnutII

Magnet doesn’t work on plaster walls. Does work on drywalls though.

You might be able to hit the nails on the lath.

But some of my plaster walls have a wire mesh in them too, so good luck with that.

my experience with plaster walls is that they're strong af. you can drill straight into them for most things, unless you're mounting a bike or something

Yes they do - normal studfinders don't work on lath & plaster walls, so magnetic's about the only option. They can be tricky, though, as the lath isn't necessarily only nailed together over studs, or like jooes mentioned, some walls use wire mesh.

We have lath and plaster construction (house built in 1941), and we have used this stud finder with success. It does a static position calibration step to determine depth of the wall before you scan. Haven’t torn in to any walls, but I don’t think we have a wire mesh back to the plaster, which may account for our success.
