A machine-mounted receiver reads the laser plane from a rotating laser. Here’s the workflow.
Set up your red-beam rotating laser on solid ground clear of the work area and switch it to rotate. Establish the instrument height above a known datum or RL — use a staff and handheld receiver if needed. That spinning laser plane becomes your reference grade for the entire job.
Fix the machine receiver to your excavator dipper arm, blade pole or machine frame at the height that matches your target grade. Use the magnet mounts for steel excavator surfaces, or the clamp mounts for round-pole setups on dozers, skid steers and box blades.
Watch the LED indicators on the receiver — or on the in-cab display if you have a D-series or MR825WD model. When the on-grade indicator lights up, your cutting edge or blade is at the correct level. Raise or lower until you hit on-grade, then work across the site maintaining that reading.
Mount to the dipper arm or grade pole and read your cut or fill depth in real time, pass after pass — no climbing out of the cab.
Consistent grade across long runs. Operators stay locked on datum without stopping the machine, cutting rework and keeping the program on schedule.
Laser grading for flood irrigation, dam construction and land levelling. Clamp to your blade pole and read grade directly from the seat.
Setting invert levels for drainage or sewer runs. Pair the receiver with a rotating laser for accurate depth reference on every bucket.
Anyone can sell a machine receiver. Few back them properly.
Metal chassis, IP66/67 rating, and 250–260mm sensor windows with four bands covering 360°. LED indicators sized for visibility from the cab, not a service counter. Made to work, every day, wherever you work.
Solid construction, built for the long term. RedBack provides in-house repair and calibration services for all RedBack lasers and most other laser brands.

It comes down to three things: how your receiver will mount to the machine, whether you want a display inside the cab, and how much information you need while you work. For excavators, a magnetic mount receiver like the MR706 or MR706D attaches directly to the dipper arm. For machines running a pole-mounted setup — dozer or box blade — a clamp mount like the MR708 or MR708D is the right fit. If you run multiple machine types and want one receiver that does both, the MR710 or MR710D includes both magnet and clamp mounts in the kit. The D models in each pair add a wired in-cab display. If you want wireless, blade tilt and plumb swing reading all in one unit, the MR825WD is the premium option.
All MR7 series receivers offer two accuracy settings. Fine mode gives you ±3–5mm, tight enough for finished grades and concrete prep. Coarse mode opens up to ±5–25mm, which suits bulk earthworks where you want faster indication without the receiver constantly hunting. The MR825WD has three settings: ±5mm, ±10mm, and ±20mm.
All RedBack machine receivers work with red-beam rotating lasers rated Class 2 or Class 3. They’re not compatible with green-beam lasers or line lasers. The MR825WD has a detection range of approximately 200m radius when paired with a Class 3 red-beam laser. See the Pair with a Laser section above for compatible options.
You want a magnetic laser receiver for excavator work. The magnet mount attaches directly to the dipper arm. The MR706 is the entry point; the MR706D adds a wired in-cab display. If you also want blade tilt and plumb swing indication, the MR825WD is the premium choice and includes both magnetic and clamp mounts.
For a skid steer, dozer or box blade setup, you need a clamp mount receiver that attaches to a 40–50mm pole or tube. The MR708 is the laser receiver for skid steer and blade work without a cab display. The MR708D adds the wired in-cab display. If you run a mix of machines, the MR710 and MR710D include both clamp and magnet mounts.
Not always, but most operators find them worth it. Without a display, you read height from the LEDs on the receiver itself. The wired D models bring that reading into the cab on a 10m cabled display. The MR825WD goes further with a wireless display that mounts inside the cab with a magnet, suction cup or clamp. If you spend long days grading or digging to level, an in-cab display pays for itself.
These are features exclusive to the MR825WD. Blade tilt shows whether the blade or bucket is tilted left or right. Plumb swing shows whether the arm is swinging forward or back from vertical. Together, they give the operator a live read on bucket angle and arm position without stopping work to check manually.
All RedBack machine receivers include a last-height-detected indicator. When the beam is temporarily blocked, the display holds the last known reading. The 250mm reception window on the MR7 series (260mm on the MR825WD) catches the beam across a wider range of machine movement before losing signal.
