Black Decker BDL190S Stud Sensor Level 2 Red Beams

Product Description

The BLACK DECKER BDL190S is a stud sensor level that combines wall scanning and leveling into a single handheld tool. It projects two red laser beams to establish level reference lines across a work surface and includes a built-in stud detection function for locating framing members behind drywall. The unit runs on two AA batteries, which are included. With a maximum measuring range of 20 feet, it is well suited for layout tasks in residential and light commercial settings. Electricians, carpenters, HVAC installers, and general tradespeople use it when mounting equipment, running conduit, or aligning fixtures on finished wall surfaces.

The BDL190S is appropriate for interior applications where both stud location and level reference are needed at the same time. Typical use cases include mounting brackets, panels, cabinets, thermostats, and electrical enclosures on drywall or plaster surfaces. The 20-foot beam range covers most standard room widths, making it practical for single-person layout work without a helper.

Installation Notes

No installation is required for this tool. Insert the included AA batteries before first use and verify beam output prior to beginning layout work. Avoid pointing laser beams directly at eyes. When using the stud sensor function, scan slowly across the wall surface and mark both edges of the stud to find center before driving fasteners.
