1. Hand Held Metal Detector Parts of Hand Held Metal Detector Principle of Hand Held Metal Detector Testing of Hand Held Metal Detector Use of Hand Held Metal Detector Specification of Hand Held Metal Detector Advantage of Hand Held Metal Detector Disadvantage of Hand Held Metal Detector WHAT YOU WILL LEARN...?

2. WHAT Is Hand Held Metal Detector...? A handheld metal detector is a security device useful for physical inspection of human traffic and small luggage and bags. The handy design improves its functionality and the high-end technology detects the presence of metals in any form including fragments. The detected metals can be produced for thorough inspection. It provides mobility to security personnel The handheld detector is quite convenient to use It is helpful in the manual inspection of human traffic The detector can search concealed metal, pieces and fragments It sends an alarm signal in the form of infrared light and sound It is suitable for checking small handheld bags and luggage

3. Parts Of Metal Detector Parts of HHMD Handle Switch Power Indicator(LED) Sensing Coil Battery Section The weight of HHMD should not exceed-250gm. It detect-05 gm of metal

4. Specification of HHMD Should be able to detect metals without being in direct contact with it. Operating temperature : 0 – 45 degree centigrade Weight should not exceed 250 gms Should be safe for pacemakers Should have both audio and visual alarms. Easily disposable / replaceable / rechargeable batteries. Indicator to indicate battery status.

5. Principle Of Metal Detector Hand held metal detectors work by  using electromagnetic fields to detect the presence of metallic objects . In simple words, they are used for metal detection through electromagnetic technology .

6. TESTING OF HAND HELD METAL DETECTOR Must be tested before each search Check that battery is fully charged Hold detector 2.5 cm (1”) from watch, belt buckle or metal object and test that it is detecting presence of metal Adjust audio control knob as necessary

7. Use Of Hand Held Metal Detector Ensure the HHMD is working properly. Greet passengers and ask for permission to frisk Ensure passenger is not holding or carrying any items Passengers shall empty their pockets for all metallic items, place these in a tray / divestment container and pass through X-ray or search physically. Ask the passenger to stand on the platform if provided. Demonstrate to the passenger the correct way to stand if required. Stand slightly to one side of the passenger and hold the metal detector approximately 01 inch (2.5cms) from the body. Move the detector over the entire body systematically (front & back) If the alarm sounds, ask passenger to check the area and to display any items found. Re-scan the area to confirm that all items have been removed. Frisking of a lady to be done by lady only.

8. Advantages of HHMD Advantage Helps in Identifying Metals both ferrous and non ferrous Easy to use Touch free checks for passenger Quick and user friendly

9. Disadvantages of HHMD Disadvantagage Cannot detect non metallic item Cannot detect non metallic replicas of prohibited items. Materials or components of IED may not be identified. Cannot detect plastic explosives May malfunction and give false alarm

10. REMEMBER- NO SEARCH, NO ENTRY
