Why does the device detect objects all over the wall?

The tool detects spots that are different from the surrounding wall. Therefore, besides objects like cables or pipes, it will also detect bigger air gaps or other differences that might appear in some walls.

What should I do if the device displays different results for the same measurement?

Follow our tips for best results and make sure to do all the measurements the same way. In particular, move the tool slightly when you put it first time on the wall (so that it recognizes the surface) and keep the outer conditions constant.

Do I need to move the tool along the surface several times in order to measure?

Due to the spot measurement you don’t have to move the tool several times. But if you put the tool on the wall and it shows yellow light you should move slightly. Then, the tool will recognize the surface and show the best results.

How can I improve my measurement result?

Apply voltage to the cable being searched for (i.e. turn on the light), remove gloves/metal jewellery, turn off interfering electronic devices, & select the correct detection setting. Hold the tool properly and avoid touching it close to the sensor.

What about the radiation of the radar sensor?

The radar sensor inside the device uses a very small radiated power to detect the objects inside the wall. The maximum power transmitted is lower by a factor of 10.000 compared to a mobile phone.
