Our M12 green ross line and plumb points laser provide all-day runtime and the best visibility in its class. Using the M12 Redlithium 3.0 CP battery， you get 15+ hours of continuous runtime for ultimate productivity. The high-intensity green laser offers you superior visibility up to 125 ft. for long-range applications. The vertical and horizontal lines make alignment and level applications easy for you， while the two plumb dots allow for quick transfers from floor to ceiling. The integrated magnetic bracket features micro-control and pivots on the plumb point for easy and fast alignment. The amplified rare earth magnets provide a strong hold and will not slide on steel studs， while an integrated hang hole makes setup easy and efficient in any environment.
