 The Topcon LS-80A Laser Receiver works with Red beam lasers to allow maximum efficiency in construction and surveying. When paired with the Topcon RL-H4C Laser, it offers an extended working range of up to 2,230 feet. It has a detective range of up to two inches and provides two accuracy modes—High (±0.04-inch) and Normal (±0.08-inch)—to ensure precise leveling and alignment.

It is equipped with a nine-channel grade indicator and height alert to position the rotating laser accurately and detect alignment discrepancy easily. Audio alerts are also available to enable use when not visible to the operator. With an auto shut-off function, it automatically turns off after 30 minutes of idleness.
