DIY'ers,first get yourself the "Hanson Stud Finder" tool .
Once you've located a spot to hang your wall mount.
Break out the Hanson Stud Finder,a pencil,and a tape measure and a level.(There is a built-in level in the walmount)
Locate screws with the Hanson Stud Finder, %26 mark all drywall screws,in area you want your wall mount to hang.
Pre-drill holes where you marked for lag screw mounts.
And walaa!
You did it,you hang the wallmount one lag screw at a time.
You just saved $$,getting the walmount at Walmart.
You just saved $$ doing it yourself.
The Hanson Stud Finder is $10, @ HD,Amazon....
P.S.
Make sure each pre drill locates wood!1
"Remember,measure twice,drill once!"
