Auto-Grade Tracking Lasers — 1-button match.
Set the receiver at the height you want, press a button, and the laser tracks up or down to lock onto it. The fastest way to set a grade — and one of the few methods that works solo. Available across the RedBack “GM” rotating laser range, paired with the LR720T / LR730T millimetre tracking receivers.
What is Grade Tracking?
Electronic Auto Grade Tracking is a radio link between the laser and the receiver. Set the receiver at the height you want on one of the laser’s axes, press the tracking button on the receiver, and the laser slopes up or down until the beam locks onto it. Auto-grade matches in seconds — fast, accurate, repeatable.
It’s one of the most efficient ways to set a grade available on the market — and crucially, it lets one person do the job. Compare that to manual slope-setting, which often needs two: one at the laser dialling in the slope, one at the staff calling out whether you’ve gone too far. With Grade Tracking, the laser does the dialling for you.
Not every RedBack rotating laser features Grade Match — only the models with a mm tracking receiver (LR720T / LR730T) and “GM” at the end of the product name. The four lasers below all share the feature, with three tiers of capability layered on top.
RedBack Auto Grade Tracking Lasers
Four “GM” rotating lasers, every one with auto grade tracking to the mm receiver. Pick by what you need on top of grade tracking — vertical alignment, green beam, or digital dial-a-grade.
Auto Grade Match
Automatic grade setting with tracking in the horizontal plane to the mm receiver. The entry point — same auto-track magic, simpler feature set, lower cost.
Auto Grade Match + Auto Align
Adds vertical-plane auto alignment to the grade tracking — the laser can be set on its side and tracked along a vertical line. Game-changer for fence alignment and long-range building set-out.
- Automatic grade setting in the horizontal plane
- Auto alignment in the vertical plane (fence runs, set-out, plumb references)
- Available in red beam (EGL624GM) or brighter green beam (GREEN624GM)
Digital Grade Match + Auto Align
The flagship. All the tracking and vertical alignment of Tier Two, plus a digital display that shows grade as a percentage during Auto Grade Match — read existing grades straight off the screen, dial new grades in directly without trial and error.
- Automatic grade setting in the horizontal plane
- Auto alignment in the vertical plane
- Digital display shows grade as a percentage during Auto Grade Match — easy reading of existing grades
- Dial-a-Grade direct entry on both X and Y axes for compound slopes
