best underground water detector

If you are a farm owner, company, or specialist in the field of water exploration and prospecting, the most important tool in your arsenal is obviously the underground water detector.

However, with so many models on the market, covering a wide range of price points, it can be difficult to decide which device to invest in.

There are also questions of depth detection range, mapping ability, and overall build quality to think about.

Professional users will undoubtedly benefit from real-time geographic mapping. For a farm owner exploring the land for water, such features may not be as important.

There’s also the issue of portability; a lightweight option will make scanning easier. However, the inevitable knocks and bumps that a detector will experience in its working life, means it needs to be robust too.

There are also accuracy levels to think about. How well can you fine-tune the detection in order to differentiate between the different types of water? Is the LCD screen clear and easy to read? How much data can be recorded? All of these are factors you will need to think about.

To help you in your search we have pulled together a selection of top-rated underground water detectors, (we’ve also included a pipe leak detector). Our choices are backed by verified customer reviews alongside in-house product research and analysis.
