The Spectra Precision GL1425C is a rugged and versatile dual grade laser designed for leveling, grading, and vertical alignment. It thrives in demanding job site conditions, consistently delivering reliable and accurate performance to boost efficiency. Equipped with built-in Bluetooth, it seamlessly integrates with the Spectra Precision Laser Remote App, eliminating the need for a separate remote control and enabling control via smartphone. The GL1425C is highly durable, capable of withstanding drops of up to 1 meter and tip-overs of tripods up to 1.5 meters. Its robust construction, along with full weatherproofing and dustproofing, minimizes downtime and repair costs over its lifespan. The GL1425C offers receiver options, including the HL760 Digital Readout receiver with automatic Grade Match for measuring unknown grades between two points over uneven terrain. Features PlaneLok, which locks onto existing elevations. The laser delivers impressive accuracy, with ±3.0 mm/30 m grade accuracy and ±0.9 mm/30 m/1°C temperature drift. It offers tilt-adjusted and non-tilt adjusted grade ranges, with rotation speeds of 300, 600, and 900 rpm. When paired with the HL760 receiver, the operational diameter is around 800 meters, while GradeMatch and PlaneLok work up to approximately 80 meters each. The laser is classified as Class 2, <3.4 mW, emitting a wavelength of 630-643 nm. Its self-leveling range spans ±5°, or ±8.7%. Teamed with the HL760 receiver, the radio range reaches up to 100 meters. The GL1425C operates within a temperature range of -20°C to +50°C and boasts an IP66 rating for dust and water resistance. It draws power from a 10000 mAh NiMH battery pack (included) or 4 x 1.5V D alkaline batteries (not included), offering around 45 hours of battery life. Charging takes under 10 hours, within a temperature range of 5°C to +40°C. The laser suits tripod attachments of 5/8 x 11, both horizontally and vertically.
