The Pro User BB-SF100 Stud Finder is a practical electronic detection tool designed to help locate wood and metal studs behind compatible wall surfaces before drilling, fixing or carrying out installation work. Featuring both LED visual and audible indicators, the stud finder provides clear feedback when detecting suitable hidden studs. The built-in automatic calibration helps simplify setup and provides convenient operation for DIY, decorating, renovation and general installation tasks. A low battery indicator lets you know when the battery needs replacing, helping prevent unexpected loss of power while working. The unit requires 1 x 9V battery, which is not supplied. Ideal for locating suitable fixing points before installing shelves, brackets, pictures, cabinets and other wall-mounted items, the Pro User Stud Finder is a useful addition to any home or trade toolbox.
