Here are some pictures of our 2010 portable lasers! I know they look very similar to our older models, however, if you look closely, you will find differences! The coating has been updated on the casing. This special coating makes the portable laser nearly scratch proof. That is, the outer black coating will not scratch easily even by keys and knives. On top of the physical changes, the internal scructure of laser has been completely changed from the bottom up. With the re-vamp, our 2010 portable lasers are now more powerful, more stable and just fun to have around. A major upgrade from prior portable lasers and those on the market today is the auto-shutoff function. A sensor closely monitors the laser diode within the portable laser. If the laser diode over heats, your portable laser will automatically shut off protecting the portable laser from damage.
