User Manual & Help Center
Welcome to the support page. Here you can find instructions on how to get the most accurate results from the app and solutions to common questions.
Quick Start Guide
1. Prepare Your Device
Before starting, ensure your device doesn't have a thick magnetic case, as this can interfere with the sensors. Hold your phone comfortably.
2. Calibration & Mode Selection
Open the app and select your preferred scanning mode. It is recommended to wave your phone in a "figure-8" motion briefly to calibrate the internal magnetometer before placing it on the wall.
3. Scanning the Surface
Place your device flat against the wall. Move it slowly and steadily horizontally. Avoid quick or jerky movements for the best accuracy.
4. Reading the Signals
Watch the on-screen meter. The app breaks down the magnetic field into X, Y, and Z axes. When the numbers spike or the graph peaks, you are directly over a dense object like a stud or metal pipe.
5. Adjusting Sensitivity
If the meter is maxing out too easily or not picking up anything, use the slider to adjust the sensitivity threshold. Lower it for thin drywall, raise it for thicker surfaces.
Understanding the Features
Real-Time Coordinates (X, Y, Z)
The app provides raw sensor data. The Z-axis usually represents the depth/direct magnetic pull from the wall. Watching these numbers helps pinpoint the exact center of the stud.
Haptic & Audio Feedback
You don't always need to look at the screen. Enable vibration and sound in the settings to get a "beep" or "buzz" the moment metal is detected.
Troubleshooting Common Issues
"I'm not detecting anything."
- Check Case: Remove any magnetic phone cases or pop-sockets.
- Sensitivity: Your sensitivity might be too low. Increase the slider level.
- Interference: Ensure there are no other strong electronic devices (like a microwave or large speaker) nearby.
"The readings are erratic or jumping."
- Stability: Ensure the phone is flush against the wall.
- Reset: Restart the app to clear the sensor cache.
- Recalibrate: Move the phone in the air away from the wall for a few seconds to reset the magnetometer.
"No Sound or Vibration."
- Check your iPhone's silent mode switch.
- Go to your device Settings and ensure the app has permission to use Haptics/Audio.
Frequently Asked Questions (FAQ)
Q: What exactly do the X, Y, and Z numbers show?
A: These represent the 3-dimensional magnetic field around your phone. When scanning a wall, a sudden change in these values indicates a disturbance in the magnetic field—usually caused by a nail, screw, or metal stud behind the drywall.
Q: Can I scan continuously?
A: Yes. You don't need to restart the app for a new wall. Just lift the device, move to the new area, and start sliding again.
Q: How do I know where to drill?
A: Locate the spot where the signal is strongest (the peak of the meter). We recommend marking this spot and scanning slightly to the left and right to confirm you have found the center of the stud.
Q: My signal is weak. What should I do?
A: Walls with double-layer drywall or plaster can be harder to scan. Try increasing the sensitivity setting to the maximum level and move the device very slowly.
