Spectra Precision Combination Laser Receiver - CR700

Spectra Precision Combination Laser Receiver - CR700

The Spectra Precision CR700 Combination Laser Receiver is a machine mounted display receiver used on small grading and excavating equipment as well as a traditional laser receiver mounted to a grade rod. With super bright directional LEDs, it is ideal for entry-level machine grade display, specifically on mini-excavators and backhoes. This provides instant grade information to the operator and eliminates the need for a rod man in the trench. It uses the patented light bar technology incorporated in the HL family of Spectra Precision laser receivers, providing more accurate and consistent readings than traditional methods and with fewer electronic components. It has a working radius of 1500 ft (460 m) (laser dependent) and a laser detection height of 5 in (12.7 cm) for quick beam acquisition. Six accuracy setting fit any jobsite requirements from Ultra Fine (1/32 in - 0.5 mm) to Machine Coarse (1.0 in - 25. 0 mm). Three Beeper Volumes include medium and low and loud to 110 dBA. Automatic shutoff after 30 minutes of non-use conserves battery life. Environmental standard of IP67 - waterproof and dustproof - and superior drop protection ensure minimum downtime.

Q&A

Q1: What is the Spectra Precision CR700 receiver used for?
A: The CR700 is a combination laser receiver that detects rotating laser beams for grading, excavating, alignment, and elevation control on construction sites. It can be machine‑mounted or used on a grade rod for versatile applications.

Q2: Can the CR700 be mounted on equipment?
A: Yes — it includes a strong magnetic mount for mounting on excavators, backhoes, skid steers, and other small machinery, eliminating the need for a rod person.

Q3: Is the CR700 durable for rugged jobsite conditions?
A: Yes. It features IP67 dustproof and waterproof protection and a 3 m (10 ft) drop guarantee, making it extremely rugged and reliable.

Q4: How does the CR700 show grade information?
A: It uses super‑bright red, green, and blue LED arrow displays and a digital numeric readout to show on‑grade, too‑high, and too‑low positions clearly.

Q5: What technology improves accuracy on the CR700?
A: The patented “light bar” reception technology delivers highly accurate and consistent readings with fewer electronic parts, increasing reliability.

Q6: Can the CR700 communicate wirelessly with lasers?
A: Yes. It features internal two‑way radio communication compatible with advanced grade lasers (e.g., GL400N/GL600N series), unlocking functions like Grade Match, Fingerprinting, PlanLok, and Axis Alignment.

Q7: What is the working range and reception angle?
A: Depending on the paired laser, the CR700 has a working radius up to ~460 m (1,500 ft) and a minimum 200° reception angle for broad beam detection.

Q8: What power and runtime can I expect?
A: The receiver runs on three AA batteries with 60+ hours battery life and has an automatic shut‑off feature to conserve power.

Maintenance Tips

• Clean the Sensor Window: Wipe the receiver window with a soft, lint-free cloth to remove dust, mud, or water for consistent laser detection.

• Avoid Harsh Chemicals: Use only mild cleaning solutions or a damp cloth to protect waterproof seals and electronics.

• Check Batteries Regularly: Replace or recharge batteries as soon as LED indicators dim to maintain strong signal reception.

• Inspect Mounting Accessories: Ensure the rod clamp and magnetic mount are clean and secure for stable operation.

• Store Properly: Keep the receiver and accessories in a protective case when not in use to prevent damage.

• Protect from Extreme Conditions: Avoid prolonged exposure to heat, cold, or direct sunlight to preserve electronics and battery life.

• Verify Performance Before Use: Test the receiver on-site to confirm accurate laser detection before starting measurements.
