The Quantum Lite marks a breakthrough in underground detection technology. This detector combines a layered imaging system with 2D and 3D scanning capabilities to locate buried metals, voids, tunnels, and relics with high accuracy. At its core is the ASU V35 (Active Sensing Unit) which allows you to visualise subsurface targets in detailed images showing shape, size and depth.
Designed for versatility, the Quantum Lite supports optional coil expansions (such as V10 and V25) for extended coverage and deeper detection. The user interface features a high-resolution 5-inch full-colour screen, intuitive controls, and a rugged build that withstands field conditions. Whether you are working on archaeological terrain, mineralised soil, or remote desert areas, the Quantum Lite adapts with automatic soil calibration to maintain stable and accurate performance.
This detector is ideal for locating precious metals, gold nuggets, hidden cavities and large buried structures. With its advanced imaging system and comprehensive detection capabilities, the Quantum Lite offers a professional-grade solution at a competitive price — perfect for serious explorers seeking depth, accuracy and reliability.
