L4+ Rotating Laser Level from Laser Reference

The Laser reference L4+ is a top choice for commercial ceiling, drywall, and interior contractors. It is also an excellent choice for long range exterior work when paired with the R7 receiver. It functions in the same manner as the L4, but it sports a high power visible beam and a fixed plumb beam. Like the L4, the L4+ self levels via a wire hung compensator, and is manually plumbed and aligned in the vertical mode. The fixed plumb beam is useful for transferring points from floor to ceiling (used with the P1 Plumb Plate), or for turning 90 degree angles. For outdoor work, the L4+ must be used with the optional R7 laser receiver. The transmitter has a working radius of 1000 feet (305m) with the R7 receiver and accuracy of 1/16 inch per 100 feet (1.6mm per 30m).  If you review the market for self leveling visible beam lasers, you will conclude that the L4+ sets new standards for performance and affordability.

Note that the laser must be paired with the optional W1 mount to be used in the vertical mode. The L4 has a long working radius of 750 feet (230m), with leveling accuracy of ±1/16 inch per 100 feet (1.6mm per 30m). Run time on 4 C alkaline batteries is 70 hours, or approximately 24 hours on the optional rechargeable batteries. The new R7 receiver incorporates a 5 channel display, and a choice of 3 modes of accuracy.
