The Spectra Precision LL300N Self-Leveling Laser is ideal for elevation controls, excavations, basic slopes, leveling forms and footers, concrete pours, and more. It features one-button operation, highly rugged design, and a single-axis slope mode that provides grade matching with a self-leveling cross axis for improved accuracy. With a working range of up to 1,650 feet, this rotary laser also includes a laser receiver for enhanced reception outdoors.
Self-leveling horizontally within ±5 degrees, the LL300N has an accuracy of ±3/32 inch per 100 feet and a 600 rpm rotation speed. It has a removable rotor cage that enables unobstructed 360-degree coverage and a 5/8-11 thread that allows you to mount it horizontally or vertically to a tripod. To avoid inaccurate readings, this laser level also features an out-of-level alert that shuts off the unit when knocked out of place.
With an IP66 protection rating, the LL300N can withstand adverse environmental conditions, such as heavy rain and dust. Its patented lighthouse seal protects the rotor head and glass and offers superior drop protection. Using four D-cell alkaline batteries, this rotary laser works up to 90 hours and approximately 45 hours with the optional rechargeable NiMH batteries.
Ideal for vertical applications and alignment jobs, the Spectra CR700 Combined Machine Control Receiver is a powerful machine-mounted laser detector that works with Spectra grade lasers and all rotating lasers. It is equipped with the patented Light Bar technology found in HL receivers which provides more accurate and consistent readings than traditional methods. With a 200-degree reception angle, this laser receiver works within a radius of up to 1,500 feet. It also boasts a fingerprinting technology which inhibits confusion from various lasers on the field.
This Spectra machine control receiver offers six accuracies to meet every demand in the job site. It features an internal radio that allows a full two-way communication, operation, and security lock. The internal radio also works within a height of up to 660 feet for better results. The CR700 comes with a vertical drift alarm, three beeper volumes, and super bright directional LEDs that perfectly work in all conditions.
