Spectra Precision — Dual Grade Laser Excavator Package
GL1425C-EXCAVATORMAXX-22
Spectra GL1425C-EXCAVATORMAXX-22 Excavator Laser Package with LR50 Machine Receiver/div>
The rugged GL1425C laser can withstand drops of up to 3 feet onto concrete and tripod tip overs up to 5 feet. This strength, combined with full weatherproofing and dustproofing, reduces downtime and lowers repair costs over the life of the product.
The GL1425C-EXCAVATORMAXX-22 pairs the GL1425C dual grade laser with the Spectra LR50 Machine Receiver/a> — a dedicated excavator receiver with 360° reception and a bright LED bar display built right into the unit. Grade status is visible directly on the receiver boom-mounted on the machine.

► A complete one-man excavation system — set grade, follow grade, and run your excavator without a rod man or ever leaving the seat. Everything you need to put your machine on grade from the moment you arrive on the jobsite.
The automatic self-leveling Spectra Precision® 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. 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 3 feet onto concrete and tripod tip overs up to 5 feet. This strength, combined with full weatherproofing and dustproofing, reduces downtime and lowers repair costs over the life of the product.
The GL1425C-EXCAVATORMAXX-22 pairs the GL1425C dual grade laser with the Spectra LR50 Machine Receiver/a> — a dedicated excavator receiver with 360° reception and a bright LED bar display built right into the unit. Grade status is visible directly on the receiver boom-mounted on the machine.
► How It Works — GL1425C-EXCAVATORMAXX-22
Step 1 — Set up the laser
Mount the GL1425C on the ALQR20 tripod. Dial in your grade on both axes. The laser self-levels and begins rotating, projecting a 360° grade plane across the entire jobsite.
Step 2 — Mount the LR50
Attach the LR50 machine receiver to the excavator boom using the magnetic mount. The 360° reception window catches the laser beam from any direction as the boom swings.
Step 3 — Dig to grade
Operate the excavator normally. The LR50 continuously reads the laser plane as the boom moves. The LED bar display on the receiver shows your grade status continuously.
Step 4 — Read grade from the receiver LEDs
The LR50 displays your grade status directly on the receiver with bright LED bars. You can see it on the boom from the cab. No separate display needed.
► Why This Package Wins on the Excavator
◆
LED Bar Display on Receiver
Bright LED bars show grade status right on the LR50 unit. Visible from the cab without a separate display. Fast read, no guesswork.
◆
360° Reception
The LR50 catches the laser beam from any angle as the boom swings. No dead zones, no losing the signal as the excavator rotates.
◆
Boom Plumb Indicator
Know when the boom is plumb. Helps operators stay consistent and accurate on trenching and vertical cut applications.
◆
Magnetic Mount Included
The LR50 includes a magnetic mount for fast, tool-free attachment to the boom. Stays put under vibration and movement.

The LR50 is a rugged machine receiver designed for excavator boom-mount applications. Unlike receivers that require a separate LED display, the LR50 shows grade status directly on the receiver itself via bright LED bars — visible right on the boom from the operator’s seat. 360° reception means you never lose the signal as the boom swings.
LR50 Machine Receiver KEY FEATURES
- 360° reception — catches the laser beam from any direction as the boom swings
- LED bar display on the receiver — bright LEDs show grade status directly on the unit
- Grade status visible from cab without a separate display
- Boom plumb indicator — know when the boom is vertical
- Magnetic mount included for fast, tool-free boom attachment
- Compatible with GL1425C — works directly with the laser’s rotating beam
Why LR50 (no separate display)?
- Fewer components to install, maintain, and lose
- No wiring or wireless pairing with an in-cab unit
- LED bars on the boom are readable from the cab
- Lower overall system cost vs. LR50W with separate wireless display
LR50 vs. LR50W — What’s the Difference?
LR50 (this kit): Grade status displayed via bright LED bars ON THE RECEIVER ITSELF. No separate in-cab display. Simpler, leaner, lower cost — ideal when the operator can see the boom.
LR50W: Adds a wireless in-cab LED bar display that shows grade status inside the cab. Audible tones: Fast beep = High / Slow beep = Low / Constant tone = On grade. Best when the boom is not visible from the seat or the operator prefers an in-cab readout.

■ FGC20 ELEVATOR TRIPOD — INCLUDED IN THIS KIT
SitePro FGC20ELAZ-B Heavy-Duty Fiberglass Elevator Tripod
The FGC20 is a heavy-duty fiberglass elevator tripod designed specifically for excavator grade laser applications. The crank-up elevator center column adjusts from 40" to a fully extended 90" — giving you an additional 50" of vertical reach without touching the legs. That extra height is what gets the GL1425C laser up to the level needed to align with the machine receiver mounted on your excavator boom. Without an elevator tripod, the laser sits too low to maintain a proper signal path to the boom-mounted receiver, causing unreliable grade readings or no signal at all. Quick-clamp leg locks and 5/8×11 thread mount for direct GL1425C compatibility.
