If you’ve ever wondered what’s really hiding behind drywall, the Walabot DIY 2 gives you x-
ray-like vision without tearing anything open. We put it through its paces in a see-through
test wall packed with wood and metal studs, copper and plastic pipes, and electrical lines, to see what this “visual stud finder” can really do.
What It Detects
- Wood and Metal Studs
- Pipes (Copper & PVC)
- Electrical Wires (live or non-live)
- Pest behind walls (live or dead) – detects motion or solid reflections from animal bodies
hidden inside walls - Depth Detection: up to 4 inches (10 cm) behind the surface
Setup & Design
The Walabot DIY 2 is a wireless wall scanner that connects to your iOS or Android phone
via Wi-Fi Direct. It creates its own private network, so your phone doesn’t need to be on
any external Wi-Fi network or even connected to the internet. Just download the free
Walabot DIY App, charge the unit, and it’s ready in seconds. Calibration takes under 15
seconds on a clean wall surface.
The device is palm-sized—about 5.6 × 3.2 × 0.8 inches (142.2 × 81.3 × 20.3 mm)—and weighs
around 4 oz (115 g). It uses a built-in rechargeable Li-ion battery that lasts a working day or
several weeks of occasional home use before recharging through USB-C.
Scanning Modes
Walabot DIY 2 has two core modes, just as described in Walabot.com
- Image Mode (default) – Displays graphical representations of wood studs, metal studs,
and pipes/wires. - Expert Mode – Displays the raw radar data from inside drywall revealing complex
overlaid, and intersecting objects and even pest infestations. It is heat-map-style that shows
object contours and motion.
In Our Real-World Test
- On standard drywall, Walabot DIY 2 accurately mapped both stud edges and wire runs.
- It quickly differentiated metal studs from wood, showing both shape and center.
- Pipes (both PVC and copper) showed up clearly

Connectivity & Compatibility
- Works with iPhone 8 and later / iOS 14 +
- Works with most Android 9 + devices
- Connects via Wi-Fi Direct—no router needed
Price & Value
At roughly $200 USD, it costs more than a beeping stud finder—but offers much more. You
literally see what’s behind the wall, not just where something might be. For serious DIYers,
electricians, and remodelers, that’s worth the premium.
Pros & Cons
Pros:
- Detects studs, pipes, and both live & non-live wires
- Visual interface—no guessing
- Fast setup & calibration
- Works on drywall, plywood, and OSB
- Rechargeable battery + wireless connection
- Gift-worthy tech tool
Cons:
- Not suitable for exterior stucco, lath-and-plaster, or drywall over one inch thick
- Requires a smartphone
- Battery life ≈ Full working day (remember to recharge before long jobs)
Final Thoughts
The Walabot DIY 2 isn’t your average stud finder – it’s a wall imager. For drywall and other
non-metallic interiors, it performed exactly as promised in our transparent-wall test. Add in
the companion app, rechargeable battery, and the ability to spot wires and pipes before you
drill, and you’ve got one of the most capable wall scanners available.
If you’re looking for a serious upgrade from a traditional stud finder—or a gift for a tool-
lover who already has everything—this is it.
