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
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
ineralization reaction

6.1 Ground balance calibration:
There are two calibration methods.
6.1. 1.Auto calibration:
The auto calibration is just to turn the unit on.
When Calibrate by this method, Fan-shaped
stripe , calibration , and star shape will
on LCD.display

10-15cm
6. Operations
The operation is same as Sapper detect
landmine, when detect, keep 10-15cm from the
floor and canning in the horizontal level to avoid
lowering the actual detect depth.
