Active Hand Held Metal Detector

Active hand-held metal detector 

Introduction:
GARRETT SUPER SCANNER is an active hand-held metal detector designed to find metal (ferrous, nonferrous and stainless steel), contraband or other objects carried on a person or concealed by a nonmetal object. When used properly, it is extremely effective in detecting even the smallest objects

Components/ Function:
Power Switch- To turn the detector on, set the switch to the On position. 
Audio Alert- The speaker provides a clearly audible sound whenever metal is detected. When using the optional earphone accessory, the audio alert will only sound through the earphone.
The Audio Alert also indicates battery condition. When approximately 10% of battery life remains, the sound when metal is detected changes from a warble to a steady tone.
LED Array- When the Power Switch is turned on, the Green Light will remain illuminately as long as the unit is on. When approximately 10% of battery life remains, the Amber Alert Light will turn on, indicating the battery needs to be replaced or recharged. Approximately one hour of operational time remains when the amber LED is initially activated. Whenever metal is detected, the Red Alert Light will illuminate.
Interference Elimination Button- The detector is factory set for maximum sensitivity to detect the smallest of items. This high level of sensitivity may produce alarms when approaching a floor containing rebar. Press and hold this button to decrease sensitivity to a level that does not respond to the rebar. Release button and detector returns to normal sensitivity.
Earphone/Recharger Jack- An earphone is available for “silent” operation or for use in noisy environments. The rechargeable Ni-MH battery is also recharged through this jack.
Audio Threshold Adjust- Adjustment is used to decrease sensitivity to surrounding material. Adjustments should only be made by supervisor who is authorized to set sensitivity levels.
Safety Sling- Used to assist the operator in convenient handling of the detector.
Battery Cover- Remains securely in place at all times but can be easily opened for changing the battery with no tools required.
