Spectra LL300N Rotating Laser

• Fully Automatic Self-Leveling: Once powered on, the unit levels itself quickly. If it is knocked out of level, the beam shuts off and a warning light flashes to prevent inaccurate readings (the "HI" or Height of Instrument alert).

• Long-Range Accuracy: It offers an operating diameter of approximately 800 meters (2,600 feet), making it suitable for large-scale commercial sites.

• Single-Axis Slope Mode: While primarily a horizontal laser, it features a manual slope mode. This allows you to match existing grades for basic drainage or driveway projects.

• The HL450 Digital Receiver: Our kits include the HL450 Laser receiver, which provides a digital readout of the elevation. This means you don’t have to "find the on-grade" by sliding the receiver up and down; it tells you exactly how far you are from level in millimeters or inches.

Built for the Jobsite

The LL330N is built to survive the realities of a construction site:

• IP66 Rating: It is dustproof and protected against powerful water jets (heavy rain).

• Drop Protection: It is rated to withstand a direct drop of 1 meter (3 feet) onto concrete or a 1.5 meter (5 feet) tripod tip-over.

• Glass Housing: The rotating beacon is protected by a metal sunshade with thick glass, ensuring the laser remains unobstructed even in windy or dusty conditions.
