security metal detector

Several listings advertise IP68-rated or fully waterproof components—most often pinpointers and search coils—with some kits specifying submersion ratings up to 10 m. However, other listings explicitly note the control box or display is not waterproof. Verify the specific model’s specs to confirm which parts are rated for underwater use.

Many models offer multiple alert modes such as sound, vibration, or both. Several detectors use multi‑tone audio (often three tones or different volume levels) to indicate different metal types or signal strength.

Battery types vary: some units require AA batteries while others use 9V batteries. A few kits include 9V batteries in the package, but other listings state batteries are not included—check the product details for what’s supplied.

Kits often include accessories such as headphones, digging tools or foldable shovels, carry bags or backpacks, holsters or pouches, and occasionally batteries.

Listings show detection of metals such as gold, silver, brass, aluminum, iron, and steel. Many devices include discrimination or notch controls that help separate valuable targets from unwanted metals for easier hunting.
