Description
Product Overview
The Franklin Sensors ProSensor MAX is engineered to be the most precise stud detection tool on the market. Featuring thirteen independent sensors, the device maps the full width of studs, giving users a clear visual of centerlines and edges on a bright LED display. Constructed from high‑impact ABS plastic in a vibrant yellow finish, the unit is both lightweight (1.1 lb) and robust enough for daily job‑site use. Its dimensions—9 × 4.5 × 3.1 inches—fit comfortably in a tool belt while the extra‑large form factor provides an ergonomic grip for extended scanning sessions. Powered by two AA batteries (not included), the ProSensor MAX offers a low‑battery indicator to prevent unexpected shutdowns. The built‑in bubble level ensures that every scan is performed on a true vertical or horizontal plane, eliminating false readings caused by tilted walls. Additional accessories include a pencil caddy for on‑site marking and a protective cap for the sensor head.

Usage
Designed for both seasoned professionals and confident DIY enthusiasts, the ProSensor MAX excels in a variety of environments. Whether you are renovating a historic home with multiple layers of plaster, installing new drywall in a modern condo, or framing a custom home theater, the device can detect studs through up to three layers of material, including OSB, plaster, and standard drywall. Its dual‑mode operation allows users to switch between a standard single‑layer detection mode and a deep‑scan mode that penetrates thicker assemblies, making it ideal for locating hidden metal pipes, electrical conduits, and reinforcement beams. The intuitive one‑button operation means you simply press the button, place the unit against the wall, and watch the LED bar reveal the stud’s full profile. No calibration is required, saving time on each job. The ProSensor MAX is also suitable for mounting artwork, hanging shelves, or installing curtain rods, where precise stud location prevents damage to the wall surface.
