1. it adopts the display mode of domestic practical patent technology, adopts full transparent hollowing method, cooperates with precise multi-color overprinting, and adds automatic backlight control method to enrich the display content. it solves the problem that the lcd screen is difficult to take into account in the night and daytime sunlight. at the same time, you can choose different colors of backlight: white, blue and green. in the daytime sunlight, when you feel the receiver and receive different brightness, you can automatically control the brightness of the backlight, showing a light gray background and black lcd text pattern. at this time, the backlight is completely turned off, saving limited battery energy and achieving low consumption. in the daytime and sunlight, it is useless to turn on the backlight, but it affects the display definition and wastes batteries. at night, it is set off by white backlight, black lcd display text pattern, plus multicolor overprint. can present a very clear and good display.

2. anti-scratch enhanced hardening material panel is adopted to prevent the display window from scratching and becoming hairy after the detector is used for a period of time, affecting the clarity of the transparent window and improving durability.

3. display mode of tested metal objects: frame type, simple and practical, clear at a glance, and equipped with three different frequencies of sound to distinguish different metal objects.

4. positioning target search: the left and right arc shapes are displayed respectively. when approaching the search object, the eleven rectangular lines are respectively close to the middle, which also represents the closer to the measured metal object.

5. the single chip microcomputer adopts the high performance and large capacity 8k of american microchip, risc structure, high operating speed 200ns, industrial temperature:-40 ℃ ~ 125 ℃, low power consumption characteristics: 1.1mw, wide voltage: 2.0v ~ 5.5v, ten-digit resolution a/d converter, on-chip liquid crystal display module.

6. use waterproof speaker: prevent rain in rainy days, causing deformation of speaker basin, making sound distortion smaller and silent.

7. high foam and high density rohs are adopted. for more information, see double-color thick handle for luxury popular colors rose red and black. it feels better and has a sense of the times.

8. with arm nylon strap, it saves effort and prevents falling off during the use of the detector.

9. select the function of ad hoc mold 1 and mold 2 to meet the detection speed required by different logistics sizes (factory setting: mold 1 slow speed).
