Product Description
Spectra Precision HR320 Laser Sensor – Durable, Versatile, and Jobsite Ready
The Spectra Precision HR320 is a high-quality laser receiver designed to work with all rotating red beam lasers. Featuring large front and rear LCDs with clear grade information, this sensor ensures accurate readings even in bright sunlight. It offers two on-grade sensitivity settings (fine and medium), allowing faster setups or higher precision as needed. An ultra-loud 100 dB speaker provides clear audible signals on noisy job sites, while the included C59 rod clampallows quick switching between handheld and rod-mounted use.
Its rugged design includes waterproof housing and shock resistance to withstand drops up to 5 feet (1.5 m), making it ideal for tough environments. Whether you're grading, leveling, or site-prepping, the HR320 gets the job done reliably.
PRISM GeoSystems, a trusted Spectra Precision dealer, has the HR320 in stock and available for pickup or delivery throughout Southern California, including San Diego, Los Angeles, San Bernardino, Colton, San Marcos, Imperial, Riverside, and Orange County.
