In our product recommendations, we have compiled the best models for you. You’re sure to find what you’re looking for with these line finders.

Checklist Line Finder

How It Works
  • Many line finders have multiple functions and search modes, such as:
    • Finding metal by magnetic fields.
    • Finding beams by electric fields and capacitive measurements.
    • Findingpipes by generating an electric field.
    • Finding plastic pipes by radar measurements.
  • These materials are used for gas, water or electric pipes , but also for mounting irons and stand constructions.
  • If the device hits one of the pipes, the voltage field changes and the detector shows a positive measurement result ( = pipe present in this area). Some models also emit a sound.
Accuracy
  • Depending on the model, calibration is done manually or automatically. Automatic calibration is especially grateful in stressful work situations, but also costs a little more.
  • Line finders are available with different depth detections. These vary depending on the material being searched, so be sure to check the manufacturer’s specifications!
  • High-quality devices can find lines up to 60 mm deep.
  • Drywall can usually be found to a depth of 12 – 25 mm.
What Else You Should Consider
  • Size and shape of the device, so that it is as handy as possible in the hand. Also, a rubber insert on the sides of the detector increase the measuring comfort.
  • The weight of the device and intuitive operation. Line finders that are easy to hold often have a relatively low weight (about 800 grams).
  • A display increases the comfort when reading the measured values.

FAQ About Line Finders

Which line finder should I buy?

That depends on your needs and your budget. Line finders are available from different manufacturers and with different special functions. If you also want to detect other things, such as metal or beams, it is worth investing in a multifunction device. We have compiled the best models for you on this page.

How does a line finder work?

Line finders contain a receiver and a transmitter. They emit a signal on a certain frequency, which is adjusted to the material to be searched. The signal, which is then reflected back, is evaluated by the line finder. As a result, you know exactly whether or not there is a line at a particular location.

What does a line finder cost?

The price range for line finders is very wide. Most of them are priced between 18 and 40 euros. However, there are also particularly high-quality line finders, which are then also more expensive, such as the Bosch GMS 120 from our product recommendations.
