- Remote grade change capability: Enables grade adjustments to be made directly from the remote without interrupting work at the laser head, reducing overall setup time.
- Remote automatic alignment initiation: Allows the operator to start automatic alignment sequences from up to 330 ft away, speeding up repositioning and leveling operations.
- Included as standard with GL412N and GL422N: Confirms out-of-the-box compatibility with these grade laser models with no additional purchase required.
Applications
- Grade setting and verification on construction and grading job sites where the operator is positioned away from the laser instrument.
- Remote alignment of rotary and grade lasers during site setup to reduce repeated trips to the instrument.
- Operation in low-light or dawn/dusk conditions where a backlit display is necessary for accurate remote control use.
- Compatible use with the HV302 (select packages) and as an optional accessory for the LL400HV, providing flexibility across multiple Spectra Precision instrument platforms.
