The cloverleaf handheld detector applies the EB damping system. The search coil is part of an oscillator circuit, which transmits a weak, alternating, electromagnetic field. Metal objects coming within the range of this field will cause a drain of energy. This is due to the eddy current effect and causes a change of the oscillator amplitude. The detector electronic processes this change in amplitude and converts it into an audio and visual alarm signal. A red LED signalizes the visual alarm while the detector gives an simultaneously an audio alarm, which increases in frequency upon approach of a metal object. The detector does not affect health, heart pacemakers or magnetic recording material. The cloverleaf hand scanner has an internal adjuster to adapt the detection sensitivity. On request the hand-held detector can be supplied with a cylindrical probe. This permits the precise localization of very small metal object. The Z-version has proved itself in particular for detailed checks at prisons.
