Accurate Detection of Buried Metal Objects – Even Underwater

The FUJI F-90M Metal Locator is a professional-grade metal detection device engineered to accurately locate buried metal objects beneath the ground with speed and precision. Equipped with advanced sensor technology, the F-90M is ideal for detecting valve covers, metal pipes, steel plates, and other metal components—without requiring extensive excavation.

Its waterproof search head allows detection underwater up to depths exceeding 1 meter. With an ergonomic and portable design, the F-90M is a trusted tool for utility contractors, waterworks companies, and underground network maintenance teams.

Key Features:

  • Waterproof Search Head
    Designed for operation in submerged environments, enabling detection of metal objects even underwater.

  • Adjustable Sensitivity Levels
    Five sensitivity levels allow for flexible detection depending on the object size and depth.

  • Dual Output Indicators
    Audible signals increase as the sensor nears a metal object, supported by a visual digital bar graph for added accuracy.

  • Centering Function
    Accurately identifies the center point of the buried metal object.

  • Compact and Durable Construction
    Built with lightweight yet durable aluminum housing, ideal for fieldwork.
