This is just the most genuine line measuring laser alignment tool, not the same as commonly available plastic lens laser. The glass coated lens has obvious advantages for conditions of making long distance line projection. This is just the most genuine line targeting selection for people to make the best line generation precisely and accurately. It uses the best quality inner thermal control system so as to protect both inner circuit board and laser diode in the best conditions in constant line generation. The metal heat sink thermal stabilization control system has enough space to make perfect thermal emitting in work.
Once users are making long distance line generation with red line laser alignment, it just enables the best line projection result even though users are using high powered alignment laser. Meanwhile, users should be cautious enough with powerful radiation from its inner laser diode.
