Spectra Precision HL450 Laser Receiver with Staff Holder. The Trimble Spectra Precision HL450 Laser Receiver is an easy-to-use tool that accurately measures elevations across the site, and is ideal for use with any rotating transmitter. The HL450 Features Digital Readout of Elevation, 10.2 cm Sensing Range and Anti-Strobe Sensor. A highly versatile receiver for basic and advanced levelling and aligning applications.
Digital Readout of Elevation allows faster readings by displaying the exact numerical distance from grade, eliminating the need to move the receiver to get to "on-grade". Anti-Strobe Sensor stops construction strobe lights from setting off the receiver and eliminates phantom strikes for easier identification of true laser beam signals.
