Digital multi-detector STANLEY STHT77588-0 — detects live cables, metal, wood; AAA battery-powered

STANLEY STHT77588-0 is a compact digital multi-detector designed to identify live electrical cables, metal objects and wooden studs behind walls, ceilings and floors. Powered by a single AAA alkaline battery, the detector offers a straightforward scanning workflow for pre-drilling checks and installations. The unit combines detection modes to help reduce the risk of hitting concealed services during cutting or fastening operations and is intended for use by electricians, carpenters and general DIY users.

Advantages

The device provides simultaneous detection of live conductors, metal and wood with a digital readout that helps the user quickly interpret results. Its lightweight, battery-powered design enables portable use without the need for mains connection or external sensors. Built-in indicators and audible signals support fast on-site decisions, while an ergonomic shape ensures comfortable handling during repetitive scanning tasks.

Suitable for

• Locating live electrical cables before drilling or cutting
• Detecting metal pipes, screws and framing members in walls
• Finding wooden studs for mounting shelves, cabinets and fixtures
• Pre-installation checks for electricians, carpenters and DIY projects

Key specifications

• Detection types: live conductors (AC), metal, wood
• Power source: 1 × AAA alkaline battery
• Display: digital readout with visual indicators and audible alert
• Portable, handheld form factor with ergonomic grip
• Suitable for use on walls, ceilings and floors

How to use

Switch the multi-detector on and select the appropriate detection mode for the task: live cables, metal or wood. Hold the unit flat against the surface to be checked and move it slowly in a scanning motion. Observe the digital display and visual indicators; listen for audible alerts that indicate the proximity of a target. Mark detected locations clearly before drilling, cutting or fixing. Replace the AAA battery when low-battery indication appears to maintain reliable detection performance.

Usage recommendations

For accurate results, test the detector on a known target before starting work and scan the area in overlapping passes. Avoid scanning over uneven surfaces or behind thick insulation without compensating for potential depth limitations. When live conductor detection is active, follow standard electrical safety procedures and, where necessary, isolate the circuit before working.
