Franklin Sensors ProSensor MAX stud finder — 13-sensor wall scanner, 2½" depth & LED centre/edge indicators

The Franklin Sensors ProSensor MAX is a 13-sensor stud finder that scans up to 2½" deep and pinpoints stud centers and edges with a wide LED display for fast, dependable placement.

If you hang shelving, cabinets, TVs or run wiring, accurate stud location matters. The ProSensor MAX replaces guesswork with a dense array of sensors that map the full width of studs and complicated framing, cutting down on re-drills, missed anchors, and drywall damage. It’s built for both pros and DIYers who need repeatable results on modern multi-layer walls as well as older lath-and-plaster constructions.

How does the ProSensor MAX find studs more reliably than single-sensor tools?

Instead of relying on one or two sensing points, the ProSensor MAX uses 13 parallel sensors that detect changes across a broad area, producing a clear LED pattern that reveals centers and edges. This multi-sensor layout reduces false positives and gives a readable visual width for single studs, doubled studs, and irregular framing.

• 13-sensor array for wide-area detection
• Simultaneous center and edge indication via LED bar
• Lower rate of false readings compared to single-sensor units

Can it detect studs through thick or layered walls?

Yes — the ProSensor MAX has a deep sensing capability and a dedicated second mode designed to penetrate multiple wall layers. That mode is useful for condominiums, upgraded partitions, or assemblies that include drywall plus sheathing or tile on top of plaster.

• Mode 1: standard stud detection for typical walls
• Mode 2: targets studs through two drywall layers, plaster with lath, or drywall plus OSB/plywood
• Detects through large tile and thicker wall builds up to 2½" depth

What makes it simple to use on the job or at home?

The tool is ready to scan immediately — no calibration or frequent re-zeroing required — so you can place it anywhere on the wall and start a sweep. A built-in bubble level, pencil holder, and clear low-battery indicator streamline layout and marking tasks, while the durable housing stands up to regular use.

• No calibration: begin scanning from any wall position
• Built-in bubble level and pencil caddy for quick marking
• Durable construction for professional and home use

How precise are the placement indicators for mounting and drilling?

Rather than a single point, the wide LED array shows both edges and the center of each stud, making it easier to select the optimal anchor location or avoid a stud altogether. This visual width helps when aligning anchors for shelving, cabinets, or heavy fixtures, and reduces the chance of missing a stud when hitting corners or doubled framing.

• LED bar displays stud center and edges simultaneously
• Works on single studs, double studs, and irregular framing patterns
• Precision suitable for mounting TVs, cabinets, and heavy shelving

Who is this for? The Franklin Sensors ProSensor MAX is aimed at contractors, carpenters, electricians, and serious DIY homeowners who need quick, repeatable stud location on a variety of wall types. If you regularly encounter multi-layer walls, plaster-and-lath, or require confident placement for heavy loads, this tool saves time and minimizes drywall repair from mis-located fasteners. It’s battery powered (two AA batteries, not included) and built to withstand jobsite use while delivering the extra sensing depth and accuracy not found in basic stud finders.
