Dual Grade Laser

GL1425C

New, fast, better.

The automatic self-levelling GL1425C dual grade laser is the most rugged, cost-effective laser that does three jobs – level, grade, and vertical alignment. Even in harsh jobsite conditions, the GL1425C delivers consistently reliable and accurate performance, enabling you to work faster and smarter.

Smart Laser Control

Durable Dual Grade Laser with App-Based Operation

The GL1425C has Bluetooth built in so it can work with the Spectra Precision Laser Remote App and eliminate the cost of the remote control. The laser can be controlled with your smartphone. The rugged GL1425C laser can withstand drops of up to 1 m onto concrete and tripod tip overs up to 1.5 m. This strength, combined with full weatherproofing and dustproofing, reduces downtime and lowers repair costs over the life of the product.

User Guide

The GL1425C has options for receivers. The advanced HL760 Digital Readout receiver provides automatic Grade Match which allows measurement of unknown grade values between two points over unknown ground and eliminates time consuming slope calculations.

PlaneLok automatically locks on to an existing elevation or vertical alignment point which eliminates all drift or possibility of error due to improper calibration or weather. The CR700 receiver is also an option when a machine mounted display elevation is required.

Each laser package includes the advanced HL760 Digital Readout Receiver that can be used at an operating diameter of up to 800m. The Digital Readout allows the user to get to the on-grade position faster as the distance is displayed to the on-grade position in mm, or inches, fractional inches. Wireless communication between the receiver and the laser allows advanced functionality such as Automatic Grade Matching to be achieved.

Automatic Grade Matching basically means that the laser moves to the on-grade position on the receiver and the grade is then calculated – this is generally used when a constant fall is desired but the grade may not be known (renewing existing driveways or matching existing surfaces). The HL760 can be paired with another HL760 turning the second receiver into a remote display that could allow a machine operator to see what the rodman is seeing when dipping for levels.

The GL622N is self-leveling in vertical, allowing more productivity by being able to carry out more tasks such as building axis alignment or setting 90 degrees or aligning anchor bolts. The GL622IR is not self-leveling in the vertical axis. Designed to be used on the toughest jobsites, the GL600 series can withstand a 1m drop.
