Product overview:

Spectra Precision® is pleased to announce the new CR700 Combination Detector – a step ahead in receiver technology!

Its both Machine and Measuring Staff mountable.

It has the same “light bar” technology that is included in the popular HL series of Spectra detectors and will deliver extremely accurate and more consistent results.


The CR700 attaches to machines with the included new magnetic mount, which is 25% stronger than its predecessor (the CR600 magnetic mount), resulting in stable machine mounting and a reduction in errors. With super bright directional LEDs, the CR700 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.

The kit also includes a mounting bracket to attach it to measuring staffs.

For any application, the industry-leading 3 metre (10 ft) drop guarantee with 3-year warranty, confirm that the CR700 is the most reliable and robust laser detector available.


Machine Cab Repeater: 

If the User requires a Cab Repeater, the CR700 can be radio linked with an HL760 detector. The CR700 is magnetically mounted on the machine and the HL760 viewed in the cab.


The World’s Best Laser Detectors
Spectra Precision digital readout detectors are simply the best laser receivers – without peers in accuracy, performance, reliability and warranty. The patented “light bar” technology provides more accurate and more consistent readings than traditional methods. This unique technology has fewer electronic components resulting in the most rugged and reliable laser detectors available on the market today.



Bright LED Arrow Displays – turn your head when you first turn on the CR700 because the new red/green/blue LED arrows are super bright and visible in all lighting conditions.

Magnetic Clamp – the new C71 magnetic clamp is 25% stronger than the CR600 magnetic clamp. It will not slip on the machine, no matter how rough the work is.

Light Bar Technology – patented laser reception technology delivers the most accurate, consistent and reliable performance.

Laser Radio Communication – the CR700 is radio-compatible with the GL400N / GL600N series grade lasers and the model HV302. This enables the use of time saving functions such as Grade Match, Fingerprinting, PlanLok and Axis Alignment. Radio range is up to 200m depending on orientation, conditions and paired device.

IP67 – dustproof, waterproof, weatherproof.

3 metre (10ft) Drop Guarantee – almost destruction proof, extremely robust, eliminates downtime.

Digital Read-Out – the CR700 provides the exact distance from true level, numerically. It reads up to 70mm below true level and 30mm above.

Remote Display – pair the CR700 detector with an HL760 detector and use as a remote display — very useful for machine operators and site supervisors.

"Fingerprint" feature - this means it will only pick-up the red laser beam from your Rotary laser.

Anti-strobe protection sensor. Eliminates false readings from green and amber flashing beacons via site plant and equipment.

Backlight – to enable the User to view the laser detector in the dark.

Vertical Drift Alarm – when using lasers in vertical mode, after setting up your line, let the laser detector warn you if the laser has been disturbed.

3-Year Warranty – Competitors are not even close to covering 3 years on their laser detectors.
