Best Stud Finder for Plasterboard in York: 2025 Expert Review
DR Joinery
Expert Joiner & Bespoke Fittings Specialist
Drilling into a wall without knowing what lies beneath is a game of Russian roulette. You might hit a stud, or you might hit a water pipe or a live cable. Worse still, you might assume you have a solid fixing, only for your new oak shelves to come away from the wall a month later.
In York, we deal with a mix of wall types. Modern extensions often use standard plasterboard on stud work, which is straightforward. However, our older housing stock is full of lath and plaster, where electronic sensors often struggle to distinguish between the laths and the structural timber.
In this review, I've selected three scanning tools suitable for DIYers and homeowners. Whether you need a simple magnetic solution for older walls or a digital scanner for modern drywall, these options will help ensure your alcove shelving is anchored securely.

Specs vs. The Real World
The Spec: "Deep Scan Mode"
"Detects studs through double layers of plasterboard or thick plaster."
On modern plasterboard, this works well. However, on traditional lath and plaster found in York's terraces, the uneven density often confuses digital sensors. Sometimes a simple magnet is more reliable here.
The Spec: "Centre Finding"
"The device beeps exactly at the centre of the stud for the perfect fixing."
This assumes the stud is straight and flat. In reality, timber twists and warps over years. Always drill a tiny pilot hole to confirm resistance before committing to a large wall plug or screw.
My Top 3 Recommendations
Three options to cover different needs and budgets
The StudBuddy Magnetic Stud Finder
The StudBuddy
Sometimes the simplest solution is the best. This requires no batteries and uses strong magnets to find the nails or screws fixing the plasterboard to the stud. It's particularly useful in older properties where electronic sensors get confused.
The Good
- No batteries required - always ready to use
- Excellent for lath and plaster walls (finds the lath nails)
- Simple and durable design
The Bad
- Cannot detect live wires or plastic pipes
- Only finds the fixings, not the timber itself (relies on inference)
Installer Tip:
Use this to map out a vertical line of screws. If you find 3-4 magnetic points in a vertical line, you can be 99% sure there is a stud running behind them. This is often more reliable than digital scanners on uneven walls.

Mecurate
For a more comprehensive analysis of your wall, this Mecurate unit offers excellent value. The inclusion of AC detection is vital for safety, ensuring you don't drill into a ring main while putting up your shelves.
The Good
- Detects live AC wires for safety
- Clear LCD screen makes reading easeier
- Multiple depth modes for different wall thicknesses
The Bad
- Can give false positives on textured wallpaper
- Requires calibration before each use
Installer Tip:
When scanning, place your hand flat on the wall away from the device to ground static electricity. If you don't, static build-up on plasterboard can sometimes cause the sensor to give erratic readings.

KALAHOL
If you are dealing with unknown wall makeups, the KALAHOL scanner's deep detection capabilities are very useful. It sits nicely between budget and premium, offering robust detection for studs, metal pipes, and fire lines.
The Good
- Deep scanning mode reaches 38mm (good for double boarding)
- Ergonomic design grips well against the wall
- Visual and audio indicators help pinpoint edges
The Bad
- Audio alarm can be quite loud/piercing
- Instructions can be a bit generic
Installer Tip:
Use the 'Metal' mode first to identify potential pipework. Copper pipes can sometimes be mistaken for studs by basic sensors, but the metal mode specifically helps you avoid a plumbing disaster.
