Description

The FUJI F-90M Metal Locator is a professional instrument for locating buried metallic objects. It is particularly suitable for water utilities and infrastructure maintenance teams looking for buried valve boxes, meter boxes, manhole covers and other metallic components.

Lightweight, collapsible and easy to operate, the F-90M is designed for practical everyday field use.

Accurate Metal Detection

The F-90M operates at 9.7 kHz and indicates the presence of a metallic object through both an audible signal and indicator meter.

According to the manufacturer's specifications, detection depth depends on the size of the target:

  • Ø100 mm steel disc – approximately 40 cm
  • Ø180 mm steel disc – approximately 60 cm

Reset Function

The integrated Reset function allows measurements to be stored and compared without the need for continuous manual sensitivity adjustment, making target location faster and easier under changing ground conditions.

Designed for Challenging Conditions

The waterproof search antenna allows metallic objects to be located even under water.

A high-soil-conductivity function helps minimize ground influence that may otherwise cause false or “ghost” signals.
