Overview
Q20 Foldable Underwater Metal Detector, Pulse Induction, 10 × 4 Inch Coil, Waterproof, Sound and Vibration, 46.5 × 10.3 cm, for Beach and Diving

The Q20 foldable underwater metal detector is a more professional variant of a metal detector designed for searching for metallic objects on land, at the beach, and underwater while diving and snorkelling. It features an enlarged coil measuring 10 × 4 inches, which covers a wider area and captures targets that smaller handheld detectors cannot. It operates on the principle of pulse induction, a technology particularly suitable for mineralised soils, salt water, and beaches with high salt content, where standard coils often fail and report false signals. The fully waterproof housing with a sealing o-ring allows for submersion and searching beneath the surface, making the device usable during snorkelling and traditional diving with full gear in both shallow and deeper areas. The foldable design with a collapsible coil facilitates transport and storage in a backpack or the supplied fabric bag. Sound signalling and vibration can be selected separately or simultaneously depending on what the environment allows.

  • Pulse induction technology for mineralised soils and salt water
  • Coil measuring 10 × 4 inches for wider coverage and greater depth
  • Foldable design with a collapsible coil for easy transport and storage
  • Waterproof housing with a sealing o-ring for underwater use
  • Optional sound signalling and vibration separately or together
  • Enhanced LED flashlight for use at night or underwater
  • Battery status indicator and illumination around the coil
  • Two-button control: power and mode switching
  • Loops for lanyard and anchoring ring for securing while diving
  • Option to extend the rods for traditional searching on the beach (rod not included)
  • Powered by a 9V battery, new alkaline or rechargeable battery with stable voltage recommended
  • Length when extended 46.5 cm, when folded 25.5 cm, coil width 10.3 cm
  • Contents: detector, bag, lanyard with anchor, mounting elements, user manual

The detector is suitable for treasure hunters who wish to explore beaches, water bodies, rivers, lakes, and wreck sites, where standard handheld models fail due to moisture or salinity of the environment and frequent contact with water. Pulse induction significantly reduces interference from minerals and salt, thus primarily responding to metallic targets and limiting the number of false finds in challenging conditions with high mineralisation. The foldable coil makes travelling for expeditions, diving trips, or to remote beaches easier, where a compact luggage solution is beneficial without the need for a special case or transport pouch. The lanyard with anchoring ring prevents the loss of the device when submerged in water and allows for searching without the need for constant firm grip, which eases prolonged stays at depth. A separate purchase of a 9V battery is required for operation; a new battery or rechargeable type with stable voltage is recommended to ensure reliable operation throughout the treasure hunting event or diving session.
