The HL450 is a rugged, easy-to-use laser receiver designed for both basic and advanced leveling applications. Ideal for use with any rotating laser, it features a large front and rear LCD with a digital readout of elevation—accurately displaying how far you are from grade within ±1.5 inches (±40 mm), without having to move the clamp.

A generous 4-inch (102 mm) reception height allows quick beam acquisition, while the patented anti-strobe sensor filters out interference from jobsite lighting. Built for tough conditions, the HL450 is fully waterproof and drop-tested up to 5 feet (1.5 m) onto concrete, minimizing downtime and repair costs.

Strengths of the HL450 include:

	Reliable Accuracy	Multiple accuracy settings to match your jobsite tolerances. Displays in millimeters, centimeters, feet & inches, or fractional inches.
	Reception Length	Extended reception zone allows for faster laser beam acquisition and better control in vertical applications like tilt-up or curtain walling.
	Crazy Simple Operation	Front and back displays show grade position and directional arrows. Adjustable audio tones and single-button access to key functions simplify use.
	Long Operating Time	Runs on 2 AA batteries with long-lasting performance to keep you going on the jobsite without interruption.
	Extreme Durability	Withstands drops up to 10 ft (3 m) onto concrete. IP67 waterproof housing handles dust, water, and grime. Backed by an over-the-counter exchange warranty.
