Top 5 Best Underground Water Detectors
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.
These are the results for 2021.

2. GOLD AKS Aqua Long Range Water Detector | Professional Underground Water Finder and Detection System | 1,300 Meter Depth
For a more budget-friendly underground water detector, you might look towards the GOLD AKS Aqua Long Range Water Detector.
At less than half the price of our top pick, this will be a more interesting choice for those on a tighter budget, (having said that, make sure you read the review below too if price-point is a deciding factor for you).
The Gold AKS is still a professional level machine mind you. Suitable for commercial use, the range on this beast is impressive.
The water detector can scan all layers of the ground to a depth of 1300 meters. The front range is also useful, providing the user with up to 5000 meters in detection ability.
Furthermore, you can choose the type of water you are trying to detect in the main unit settings.
Fine-tune the system with just a few clicks of a button, to recognize water types such as Salty, Natural, and Artesian. You can also check the depths of these with the automatic depth checking function.
However, it doesn’t have the high-grade geographical map-making ability that our top pick TC-900 has, but then this shouldn’t be expected at the price point we are in with this model.
A manufacturer’s warranty is available on all products from Detector Power.
The sales provider also offer a hassle-free 15-day return policy if the machine doesn’t match your expectations upon arrival.
The GOLD AKS Aqua Long is a good groundwater detector, however, for those looking for more features, there are better options.
And if you are on a budget, the GER Detect (reviewed below) is the better buy. Still, a worthy addition to our top 5 nonetheless.

3. BEST BUDGET: GER DETECT River F High Resolution Long Range Underground Water Detector
Our best budget choice underground water detector is the GER Detect River F.
As with the GOLD AKS reviewed above, this is a 3 water search instrument that allows users to detect the location of fresh, salty and natural water deposits and sources.
The unit itself can be operated via the touch screen or the keypad, and the different search attributes can be selected with a few taps of a button.
Essentially, the Ger Detect River F can detect underground water sources as well as artesian wells. The range for such detection is good too.
While not as wide as the Gold AKS, you can still reliably scan and detect to a depth of 1300m, with a front range of 3000m.
It is also easy to pick up and use. Opting for a pistol grip style mode of operation, you can literally, begin scanning the terrain with the press of a button.
The unit features a built-in digital compass so that users can set the north and south directions before they begin to search the terrain.

4. Deep Water Detection PQWT-TC500 Accurate Instrument for Water Well Drill
The TC500 is another PQWT device to make our top 5. While not as packed in features as the TC900, (nor does it have the same high range), this is still a top-quality instrument for underground water detection.
Utilizing the same patented technology as our top choice, the TC500 can also automatically provide a visual representation of the substances detected under the ground.
The TC500 will give you an understanding of the subterranean geological structures in the most user-friendly manner. As a portable water finder, it really is a great device.
However, one negative (and this is related to the lower cost nature of the equipment), the depth range is only 500m. To obtain greater power and detection ability you will need to buy one of the more premium devices.
That being said, if the 500m range is suitable for your needs the instrument is easy to pick up and use.
From a novice perspective, the device uses a single selective menu, with the options being intuitive and simple to understand.
For the professional user, it is important to know that the manufacturers state that the data acquisition accuracy rate is up to 0.001mv.
Also, relevant for commercial use is the fact that once data is collected, just one button will initiate the mapping of geographical features, with depth measurements being traced too.
Underground water prospecting really is efficient with this tool, (as long as 500m is deep enough for you).
For the price, the PQWT TC500 packs a lot of very impressive features. The one-button geographical map-making ability is especially beneficial.
However, as we have covered throughout the review, with only 500m depth capacity at your disposal, this is a unit that you need to think carefully about buying. Is that detection range suitable for your needs?
