Metal Detecting Guides & Reviews

UIG's Gold Digger is a VLF detector; the Ground Scanner and Watch Detector are 3D imaging devices. Here is how their manufacturer-stated specs compare and who each one fits.

What BR Systems says the Gold Step Pro Max does, how its 3D imaging and live-scan functions work in practice, and who this ground-scanning detector realistically suits.

Mega Detection's Mega Scan Pro and Gold Star 3D Scanner compared on manufacturer-stated sensors, systems and software, with realistic notes on what scanners can show.

Mega Detection's Infinity Max Pro packs 12 manufacturer-stated search systems into one kit. Here is how they map to the sensors in the box and who the platform suits.

The Mega Detection Phoenix is a 3D ground scanner; the Viper pairs a long-range locator with three PI coils. Here is how their systems, workflows and ideal users differ.

From prospectors and cache hunters to archaeologists, engineers and search teams, here is who uses subsurface scanning, what each group is looking for and which tools suit each job.

How ground scanner software turns raw readings into 2D and 3D images, the settings that matter, how to save and export scans, and the display pitfalls that make empty ground look like a target.

Some professional detectors advertise 5, 8 or even 12 search systems. Here is what those systems typically are, which rely on established physics, which are manufacturer claims, and how to decide what you actually need.

How cavity detectors and ground scanners find tunnels and hollows, how professional geophysicists approach voids, what limits detection and how to confirm a cavity before you dig.
