The real benefit here is that you won’t have to swap out lasers between tasks which increases the chance of losing your original point of reference. Ultimately, this laser helps to improve your overall accuracy by eliminating the need for extra movements.

This laser level features three modes that alternate between vertical, horizontal, and cross line laser projection. Its high-intensity green laser has an effective range of 165 feet when used with a detector and the 3.0Ah battery gives you around 9 hours of total runtime.

Another major highlight is a fine adjustment knob. Once you get the vertical beam close to where you want it, use the adjustment knob to dial it in precisely. The really nice thing is that adjusting the vertical beam doesn’t change the plumb spot you’re lining up with, which is a huge time-saver.

  • Keyhole mounting point
  • Compatible with all Milwaukee M12 batteries
