1.Introduction
Thank you for choosing Smart Sensor Metal
Detector. This unit adopt latest electronic technology
+
provide with ground balance function which can
eliminate the effect caused by Mineralization
",
reaction besides the metal type mode can identify
that the detected subject is ferrous or non-ferrous
metal, enhance the effectively detect depth &
accuracy. It is easy to operate with big probing
、
depth accuracy appointed high resolution
features. In order to take full advantage &
functions of metal detection, please
read carefully before using this manual.
1.1 Application
Except for the military purpose, This unit
also suitable for following fields:
Police quick searching
Metal object detection in material, fuel,
food stuff
Metal object detection on mail, baggage
Hunting buried pipe, cable
Relic & Mineral hunting
Cache treasure & mineral hunting
1.2 Mineralization reaction
The kinds of the minerals which consist of soil
can make unit send signal. When using old type
metal detector, the signal changed with distance
between sensor and floor, if use sensor scan the
rough floor, the signal change a lot. on the complex
soil place, the signal caused by soil is much bigger
than metal, this phenomenon named
