Determining elevation on the jobs site is simple when you have this Laser Receiver with Rod Clamp (HL450). It provides a digital readout of elevation displayed on its large front and rear LCDs, so it's easy to see. It allows you to take accurate measurements without having to move the rod clamp, saving you time and increasing productivity.  It has a 4" reception height, which is double the typical industry standard, and its anti-strobe sensor prevents construction lights from setting off the receiver.  Plus, it makes it easier to identify laser beam signals.
