1、The display method adopts domestic practical patent technology，Use the fully transparent hollowing method，In coordination with precise multi-color overprinting，Add an automatic backlight control method，Enriched the display content。解决了液晶显示屏At night和Under the daytime sunlight难以兼顾的问题。At the same time, backlights of different colors can be selected：white、blue、green。In the daytime sunlight，When a sensory receiver，When receiving different levels of light brightness，Automatically control the brightness of the backlight，It presents a light grey background，Black liquid crystal text pattern。At this point, the backlight is completely turned off，Save the limited battery energy，做到低消耗type。Under the daytime sunlight，Leaving the backlight on is of no use，Instead, it affects the display clarity，Problems such as battery waste。At night，Set off by a white backlight，Black LCD displays text patterns，Add multi-color overprinting。It can present a very clear and good display。

2、The panel is made of scratch-resistant reinforced hardening material，Prevent the detector from being used for a period of time，The display window is scratched and frayed，It affects the clarity of the transparent window，Improve durability。

3、The display mode of the metal object under test：Framed type，Simple, practical and clear at a glance，It is also equipped with three different frequencies of sounds to distinguish different metal objects。

4、Target location search：Display left and right respectively2Arc-shaped strip，When approaching the search object，The eleven rectangular lines are respectively moving closer to the middle，It also indicates that the closer it is to the metal object being tested。

5、The single-chip microcomputer adopts the United States.MICROCHIPHigh performance and large capacity8K、RISCThe structure has a high operating speed200ns，Industrial-grade temperature：-40℃~125℃，Low power consumption feature：1.1mw，Wide voltage：2.0V~5.5V，Ten-digit resolutionA/DConverter、片内液晶显示die块。

6、Adopt waterproof horn：Prevent it from getting rained on，Cause the horn paper basin to deform，Reduce sound distortion and make it silent。

7、Adopt high foam and high densityROHStype，豪华type流行色玫瑰红与黑色详见双色粗大手柄，Better hand feel，Full of a sense of The Times。

8、It comes with nylon arm straps，Save effort and prevent detachment during the use of the detector。

9、特设die1、die2"Selection function"，To meet the detection speed requirements of different logistics sizes（Factory Settings are：die1Slow speed）。
