The new PLS 6 and PLS 180 red and green laser levels offer the durability and precision you expect from PLS, a Fluke Company. We’ve replaced the PLS 4 red with the PLS 6 and created both a red and green version. The fast settling, self-leveling pendulum gives you accurate point and reference lines almost instantly. Additionally, these products feature a pendulum lock to secure the laser during transport or if dropped.
