Below is pictured the Worth Data LZ200 Laser Scanner, which has a 3 year
warranty. (It reads up to 20 inches from a typical medium density bar code).
The basic laser scanners read up to 10-20" distance, depending on the brand of
the laser scanner. There are hand held triggered long range laser scanners that
can read up to 33 feet distance, (using retro-reflective low density bar codes) or
10 feet distance using paper low density bar codes. Long-range laser scanners
are naturally more expensive than the standard laser scanners.
We have tested the LZ100 and the LZ200 by aggressively throwing (not just
dropping) them to the floor. They survived every repeated throw. The scan
element has a lifetime warranty; both scanners use models of the Symbol 1200
Scan Engine, (this engine is rated to withstand 2000Gs of force on impact). We
developed this laser scanner after years of frustration with other laser
manufacturers' product reliability. Symbol lasers had superior reliability to
anything else we sold, but they were difficult to integrate with our reader's
unique feature offerings. Therefore, we were forced to manufacture our own
laser scanners using Symbol engines. Being the manufacturer, we can more
closely control function and reliability.

These devices are continuously emitting multi-directional light beams to
maximize the reading of a bar code regardless of the orientation of the bar code
