NOYAFA GMT-NF-5107S-1 Stud Finder with Adjustable Sensitivity

The NOYAFA GMT-NF-5107S-1 stud finder scans for wood, metal and AC wiring, with adjustable sensitivity and a backlit LCD. Its listed detection depths vary by target type, so choose it for locating likely positions before mounting or drilling, not as a substitute for verifying wall conditions.

At a glance

Three scan modes cover wood studs, metal and AC wiring, with a separate stated maximum depth for each target.
Sensitivity and depth can be adjusted for the listed detection types. The listing describes lower sensitivity for thin drywall and higher sensitivity for thicker plaster.
Backlit LCD is claimed to show mode, signal strength, depth reading, battery level and target direction. Beeps are said to increase in frequency as the device approaches a target center.
A positioning hole is listed as a feature, but the supplied details do not explain its use or operation.

Pros and cons

Pros

One tool combines wood, metal and AC wire scanning, with mode-specific detection-depth claims.
Adjustable sensitivity may help adapt scanning to different wall conditions.
LCD and audible signals provide visual and audio cues during scanning.
The feature description claims a built-in rechargeable battery and USB Type-C charging.

Cons

The deepest stated scan is for ferrous metal, while wood and AC wire have shallower listed maximum depths. The appropriate mode and target matter when planning a scan.

Customer feedback highlights perceived accuracy and functionality, including mention of circuit and wire testing. That is relevant to the listed metal and AC-wire scan modes, but ratings alone do not verify the stated detection depths or establish performance in every wall type. The overall rating distribution is mostly five-star, with a smaller spread across lower star categories, so experiences are not uniformly positive.
