The Stanley Stud Sensor Finder S50 (77-050) is a reliable and easy-to-use wall scanner designed to detect wooden and metal studs behind walls at depths of up to 19mm (3/4"). Whether you’re hanging shelves, mounting TVs, or planning renovations, this stud finder takes the guesswork out of locating wall framing quickly and accurately.

Auto calibration ensures the sensor is ready to use straight away, while the intuitive LED indicator system — green for power, red for stud edge detection — makes readings clear and immediate. The built-in marking channel lets you mark the stud edge directly on the wall without repositioning, and the soft grip design ensures comfortable, controlled use. Water-repellent construction adds durability for use in a range of environments.
