Because you have no idea precisely what is in your walls use a sonic stud finder and scan the wall through the speaker placement to either the best on the wall or to the floor.. Mark any studs that are during the way by using a light pencil mark. Offered the common spacing applying to frame most homes, look forward to finding most studs 16 or 24 inches from centre. Scan the walls together with your sonic stud finder horizontally marking your studs and then vertically, marking your studs. You are going to locate a stud close to the bottom at floor degree and you also will find a stud on the leading on the wall.
