Best for Hanging shelves and TVsfinding studs in drywallmounting brackets

Most DIY frustration starts with a wall: the anchor that spins in drywall, or the third hole drilled “just next to” the first two. A typical stud finder beeps at one edge and leaves you guessing where the stud actually is.

The M210 uses a row of 13 sensors, so the LEDs light up across the whole width of the stud at once and the middle one turns green on the center. That’s the spot you want for a screw. It also finds double studs, which usually means a door or window frame is close by.

Pro tip Confirm a stud before you drill a big hole: a small finish nail in the marked spot should hit solid wood within the first half inch. Patch the tiny hole later with a dab of spackle.
