This unit is a compact, lightweight, durable and easy-to-operate hand-held metal detector for use in detecting metal objects on a person’s body. It is ideally suited for use in any security situation. One simple tuning control allows adjustment for various sizes of metal objects and situations, depending upon specific needs. The SEARCHALERT ® is capable of detecting a paper clip from two inches away, or, with a quick adjustment of the control, smaller objects such as loose change or keys can be easily bypassed, and metal objects of larger size only will be detected. Physical contact is not necessary on body searches due to the pinpoint accuracy of the unique case-mounted Faraday-shielded search coil. The SEARCHALERT ® detects all metals, both ferrous and nonferrous, and produces both a visual and audible alarm with its built-in 2 1/4" speaker and case-mounted LED. For private alarm indication, the optional earphone attachment (MI45E) ensures that only the operator is aware of the alarm by disabling the speaker and LED and channeling all audio directly to the earphone. A rechargeable nickel-cadmium model (MI45RE) is available.
