Bosch D-TECT 120 Wall and Floor Scanner Stud Finder

The Bosch D-TECT 120 Wall and Floor Scanner is a professional radar-based detection instrument engineered to locate hidden wood studs, ferrous metals, non-ferrous metals, live electrical wiring, and plastic pipes beneath drywall, concrete, and subfloor surfaces. Utilizing ultra-wide band (UWB) radar technology to deliver a maximum scan depth of up to 4-3/4 in., this calibration-free device features Spot Detection technology for instant object identification without sweeping. Equipped with a traffic light color-coded LCD display, directional indicator arrows, and three specialized scanning modes (drywall, universal, and concrete), this 1.1-pound detector prevents accidental utility strikes during commercial construction and renovation tasks.

Best Used For:

  • Electrical Outlet & Conduit Installation: Scanning concrete walls and drywall partitions to identify hidden live electrical wires and plastic conduit before coring or anchoring.
  • Plumbing Pipe & Rebar Clearance: Detecting embedded copper water lines, steel rebar, and PVC pipes behind tiled surfaces and concrete slabs prior to drilling.
  • Commercial Framing & Heavy Wall Anchoring: Locating wooden and metal stud framing bays accurately behind thick wall assemblies to secure heavy wall mounts.

Key Performance & Safety Features

  • Ultra-Wide Band Radar Sensor Array: Advanced radar technology detects hidden objects up to 4-3/4 in. deep across multiple construction substrates.
  • Instant Spot Detection Technology: Identifies hidden objects immediately upon contact without requiring manual calibration or side-to-side sweeping.
  • Traffic Light Color-Coded Display Interface: Illuminated LCD screen uses red, yellow, and green indicators alongside directional arrows to pinpoint object centers.
  • Three Dedicated Scanning Modes: Switch easily between Drywall, Universal, and Concrete operational modes to optimize detection sensitivity for specific materials.
  • Calibration-Free Ready-To-Scan Design: Powers on instantly with zero setup delays or manual adjustment requirements.
  • Ergonomic Soft-Grip Housing Profile: Compact, lightweight body fits comfortably in the hand to reduce fatigue during extended whole-house scanning sessions.

What's Included

  • (1) Bosch D-TECT 120 Wall and Floor Scanner
  • (4) AA Alkaline Batteries
  • (1) Hard Protective Storage Carry Case
