Metal Detecting Guides & Reviews

Start with the target, not the spec sheet. How to choose a metal detector for gold, coins and jewelry, relics, deep caches or groundwater surveys.

Farm and ranch wells need higher yields and face tighter rules. How to size demand, check water rights, narrow sites across large acreage and use NRCS programs.

GER Detect's three water detectors compared: River F Smart, Fresh Result 2 Systems and River G 3 Systems, by manufacturer-stated systems, probes, imaging and support.

BR 950 vs BR 950 Max: a focused groundwater locator versus a multi-mode probe-based platform. What BR Systems states, what is included and who each one suits.

An honest 2026 buying guide to groundwater detectors: River F Smart, BR 950, Fresh Result 2 Systems, BR 950 Max and River G 3 Systems compared by stated features.

Water dowsing, electronic water detectors and professional geophysical surveys compared honestly, with what the USGS and EPA say about each approach.

Groundwater detectors use resistivity probes, long-range modes or both. Here is what the science supports, what is a manufacturer claim, and how to use one responsibly.

The most reliable way to find underground water is to stack evidence: well records, geology, a survey and a licensed driller. Here is how each method compares.

Metal detectors cannot detect groundwater. Learn the physics, the methods hydrologists actually use, and where electronic groundwater detectors fit in.
