3 EZ step to find a stud:
  Step 1. Place EZ Stud Finder vertically and flat against the wall, using the level as a handle.
  Step 2. Slowly move EZ Stud Finder across the wall. When you see one or two magnet(s) move, you have found a stud.
  Step 3. Take one of the two magnetic markers and place it at the position where the magnet moved. The magnetic marker
               will stick to the wall.
