High Performance Hand Held Scanner – MD-3003B1


  • The MD-3003B1 is a high performance Hand Held Metal Detector designed to meet the exact requirements of the security industry.
  • Typical uses will include body search for offensive weapons in crowd control, airport and border security, checking parcels and letters for metal objects and anywhere that hidden metal needs to be detected.


  • The MD-3003B1 operates on one 9Volt standard or rechargeable battery.
  • To install the battery, slide off the battery cover and place the battery into its compartment while matching the +/- symbols.
  • Turn the unit on by pushing the on/off switch until it clicks on and the green LED is lit.
  • The detector is now operational although an increase in sensitivity and depth range can be achieved by turning the sensitivity adjuster until the red LED is lit and a constant audio tuned is heard.
  • Turn the sensitivity adjuster (anti-clockwise) until the red LED just goes out and the tone fades.
  • The detector is now tuned for optimum sensitivity and depth range.
  • Holding the unit with the detection face towards the surface, sweep backwards and forwards continuously at a height of 10-30 mm above the area to be scanned.
  • The presence of metal will be indicated by the audio warning tone and the red light coming on.
  • If the detector is held still over a metal object the detection signal will automatically reduce, therefore it is important that the unit is continually scanning the surface when in use. 


  • Press the low sensitivity switch during detection, scanner will then only respond to bigger metal objects such as a hand gun, knife, etc and will not respond to small metals such as a coin, key, hatpin etc.
  • Do no release the low sensitivity switch until you complete low sensitivity detection.


  • The detector is equipped with a vibrator button also located at the side of the detector.
  • Vibration function should be used in noisy work situations or in places where the operator does not wish for the audio tune to be heard in his surrounding area.
  • Press this button, vibrator works, release it, audio tune works.
  • If the green light goes out completely or fails to come on or if the unit is making unfamiliar audio tunes, the unit is unstable and should not be used until the battery is recharged or replaced.
  • If the unit is not to be used for a certain length of time, it is advisable to remove the battery to avoid battery leakage which could cause serious damage to the detector.
  • When not in use, the detector should be stored in a dry warm environment.
