What are the best techniques for locating studs behind drywall?

One of the best techniques for locating studs behind drywall is to use a stud finder tool. This handheld device can detect the presence of studs by sensing changes in density within the wall. Another method is to look for visual clues such as nail heads or seams in the drywall, which may indicate the location of studs. Additionally, tapping on the wall and listening for a solid sound can help identify the presence of a stud.
