What stud finder will work on 3/4" plywood over 5/8" sheetrock? Bought a Franklin M210 and it is not doing the trick.

Stud finder help please​


This isn’t going to work! I think I left mine on my bedside table at the lake. I was looking for it the other day.
In all seriousness I have no idea. Maybe some kind of thermal camera might work in a cold location. Maybe in Arizona it would work in reverse.

Here are several recent discussions of stud finders, maybe one will help.


This one looks promising

All the threads with stud finder in the title

To be clear, you want it to read thru 1 3/8" of material (3/4 plywood, then 5/8 drywall to find studs)? Good luck, I think the plywood density will throw off most of the finders (my understanding is they can ignore the drywall density, and look for the wood/air difference).

You might have to go deep (into your pocket)


doesn't really say about going through both wood/plaster, but as other have stated the others don't really work well on wood at all.

I doubt that any traditional stud finder will see wood studs behind wood.

You may need to look at a radar based wall scanner.

I've used a HILTI that was north of $20k several years ago, and it was pretty cool.

Tommy Silva just raps his knuckle on the wall and voila, stud. Of course this probably works on drywall alone. Maybe tapping a hammer on the plywood will ring differently when you get over the stud. Hunting for nails or screws through plywood and drywall is a fools errand without the high price product, I would imagine, as stated already.

NOTE: since the plywood is over the drywall as you state in initial post, aren't the fasteners in the same line on the stud, and can't you see the fasteners with your eye???!

I see this is your first post! Welcome to the Forum!

I assume that the 3/4”plywood is screwed into the studs too. Take a magnet and find the vertical rows of screws that are holding the plywood on and you will probably find the studs right behind them. Another thing is that electrical outlets and wall switches are usually right next to a stud.

You want the Franklin MAX. Well worth the $100+ it costs for really thick materials on the stud.

A magnet will find the screws that hold the plywood up. If those screws are regularly spaced out then you found your stud.

I have one of the OG Franklin sensors. Its very good at working with drywall, but even the mighty Franklin cant see through plywood. Id be very interested if the Max actually can. Franklin is the best Ive ever used so if anybody can pull it off, it would be them.

Myself, Id be trying to see if I can see the studs using a borescope and go from there.

For my typical use cases all of the plywood is a stud.

If I really needed to know where the studs are I'd first look for outlets, use a magnet figure out which side of the outlet had the stud it was attached to, and continue to use the magnet to find the rest of studs which would go quick once I figured out they were on 16" or 24" centers. I'd have all the studs marked in a room before you got that Franklin Max out the box and the batteries put in it.

Use all the info in this thread, make your guess and drill a small hole. If you miss, move over a little. Keep at it until you hit. Then every 16". Good luck.
