Science structure: Able to fall from 1.7m drop to concrete, with no damage!
A.  Very strong laser head, just like the famous brand- Symbol's, but the weight is lighter than Symbol so it's firmly and no damage when it fall. Not like the regular machine only stick units on PCB with no construction. Our laser engine is very well.
B.  Pragmatic science manufacture processing, our plane mirror is gild directly on the plastic, just like Symbol. Not like normal manufacturers using thin mirror stick on it, the thin mirror will broke very easily, fall off very soon.
Window prevent stain scar: Using import quartz lens from Europe, using metal types needle to rub the window won't get any scar, not regular product using plastic for window.
Reading window using for long time will get dirty. While the window dirty will using cloth to clean the window, normally after cleaning the window will get unclean. Scanning window just like the laser scanner's eyes, fuzzy window will let the decode ability down, or cannot decode. But our prevent scar window, won't have this problem.

One and only orientate scan line on the stand:
Easy quickly find the scan line position, don't need to take barcodes to test the scan line position. Stand's height could be adjusted. The angle could adjust to vertical and horizontal to read the barcode. Not like the normal function for put, but more.

Confirm the scan line using rubber band to locate.  
Confirm again that the scan line is appear on the rubber band.  
After that, scan is very easy, just aim at the rubber band.  
Operate faster, easiler.

Vertical and horizontal all ok.  
Horizontal scanning.  
Vertical scanning.  
Higher the stand to read big item.
