The Spectra Precision CR700 Combination Laser Receiver is a machine mounted display receiver used on small grading and excavating equipment as well as a traditional laser receiver mounted to a grade rod. The CR700 includes both a magnetic mount for quick machine mounting and a grade rod clamp. With super bright directional LEDs, the CR700 is ideal for entry-level machine grade display, specifically on mini-excavators and backhoes. This provides instant grade information to the operator and eliminates the need for a rod man in the trench. The CR700 uses the patented light bar technology incorporated in the HL family of Spectra Precision laser receivers. This unique technology provides more accurate and more consistent readings than traditional methods and has fewer electronic components resulting in the most rugged and reliable laser receivers available. It is also ideally suited to work in vertical application for alignments control. The LEDs are visible at long range and a vertical drift alarm warns if the laser is disturbed.
