Pacific Laser Systems just launched 2 new green lasers the PLS3 Green Laser ($329, Ohio Power Tool) and PLS180 Green Laser ($479, Ohio Power Tool). These higher visibility green lasers has been something contractors have been requesting for years and PLS is not the first to launch a green dot or line laser. They have however done the best job at addressing the largest complaint about green lasers which is battery life. You can expect about 6+ hours of continuous use for these new lasers which could mean a few weeks depending on usage.
Previous attempts at the green lasers from some competitors had only been able to produce 1-2 hours of continuous run time so did not see wide adoption. When compared to the red dot PLS3 ($205, Ohio Power Tool) or the red line PLS180 ($282, Ohio Power Tool) however even the new PLS green lasers 6+ hours, it is still only about 20-30% red laser run time. Certainly with rechargeable batteries this would become much less of a concern but it will just depend on usage and personal preference. They are available for pre-sales now with an expected shipping date in early December. Call the pros at Ohio Power Tool 800-242-4424 for more information or questions on any laser measuring tools.
