Stud Finder

The NT-6357 is a wall scanner with a 2.4-inch color display. It detects ferrous and non-ferrous metal, wood studs, PVC water pipes, and energized AC wiring. Three-color backlighting and a buzzer indicate calibration and target location.

It is suitable for drilling during renovation, mounting brackets, woodworking, plumbing and electrical work, and preliminary location of concealed services. Before drilling into a wall, scan for possible rebar, wiring, water pipes, or wood studs to reduce the risk of accidental damage.

Official specifications state a maximum depth of approximately 10 cm for ferrous metal and 8 cm for non-ferrous metal. Actual depth depends on material size, wall construction, moisture, and scanning technique and is not guaranteed in every situation.

The stated depth for wood studs, wood strips, or some PVC pipes is approximately 3 cm, supporting shallow positioning behind a wall surface. Plastic-pipe detection depends on the material inside the pipe and the wall construction, so scan repeatedly from multiple directions.

The stated energized-wire detection depth is approximately 5 cm, but sensitivity may change if the circuit has no load, is shielded by metal, or is in a damp environment. Disconnect power and verify the location by another method before drilling.

Yellow indicates calibration in progress, green indicates calibration complete, and red indicates a detected target. Recalibrate whenever changing wall surface or mode, and begin away from the suspected target.

Hold the scanner flat against the wall and move it slowly horizontally or vertically with consistent speed and pressure. Scan repeatedly from different directions, mark the boundaries, and use the intersections to estimate the center.

A wall scanner reduces risk but cannot guarantee that every concealed object is excluded. Review building plans, shut off the relevant electrical circuit and water supply before drilling, and have a professional verify high-risk locations.

Keep the sensing surface clean and flat. Stickers, metal particles, or thick protective films may affect readings. Remove batteries for long-term storage or charge and discharge according to the instructions, and keep the housing dry.

The NT-6357 searches for metal, wood, pipes, and energized wiring and is suitable for a broad pre-drilling check. A basic NCV detector primarily senses an AC electric field and cannot replace structural wall scanning.
