put the stud finder against the ceiling -then turn it on and move it.another way is to put the sensor on metal and hunt for the screws.also try deep scan mode.your joists will be at 16 " centers.if you still dont have any luck,put a tiny drill bit in a drill and drill into the ceiling at 3/4" spacing.any resistance will be your joist and you can patch the tiny holes with a dab of dap caulking

tried that, didn't work. going a different route!!!

Wish you luck

When I mounted my 35lb 48" ATI, I had to use a 52+" piece of 1/4x1-1/4 flatbar as the tank was not sitting perfectly under the joists
I put 4 - 3" screws into the joists to hold the bar
I am very happy with how solid it is

The best way to handle this is to find a light in the ceiling that is existing close to the area, the light fixture will be attached to one side of the joist. If it is a 2 storey they will be 16" apart. If it is an attic or roof they will be 24" apart.

Is there a ceiling fixture you could take apart to find where the joists are ?

So ....
Any luck with the new stud finder ?
I mean besides it going off when you turn it on, you big studd you :razz:

try shining a bright flashlight across the ceiling while it's dark if you have a smooth ceiling-you should be able to see the taping joints.drywall is laid across the joists.it sometimes works with a textured ceiling as well
